Genetic Analysis of some Crosses for Yield and its Components and Earliness in Pea (Pisum sativum L.).
Crosses among six pea cultivars viz., Master, Entesar 1, Little Marvel, Entesar 2, Palmoral and Jaguar were achieved. The investigation was carried out at the Sids Horticultural Research Station of the Agricultural Research Center, Beni-Suef Governorate, during the three winter seasons of 2015/2016, 2016/2017 and 2017/2018. Fifteen crosses were made between the parents. The recorded measurements were plant height, number of days to flowering, pod length, pod width, number of seeds/pod, weight of 100-seeds, number of pods/plant and weight of pods/plant. The parents of Entesar2 and Entesar1 showed the best mean performance followed by Jaguar for the most studied traits. The cross combinations of Entesar1 x Entesar2, Entesar1 x Master and Entesar1 x Little Marvel showed the best mean performance for the most studied traits. The F1 hybrids of Master × Little Marvel, Little Marvel × Master, Entesar1 x Entesar2, Entesar1 × Little Marvel, Little Marvel × Entesar1 and Master × Palmoral exhibited a heterosis for the most traits. The obtained results of mean performance, heterosis and potance ratio demonstrated that the hybrids of Master × Little Marvel, Little Marvel × Master, Entesar1 x Entesar2 and Entesar1 × Little Marvel are the best hybrids. Plant height, number of days to flowering, pod width, pod weight and number of pods/plant were positively and significantly correlated with pod yield per plant, which are of great importance as selection criteria for yield improvement of pea.These findings can be utilized further in selection programs to enhance the yield potential of pea genotypes.

Enhanced indirect organogenesis and efficient shoot multiplication of Petunia hybrida
A study was initiated through various experiments aiming to optimize different stages including callus induction, shoot regeneration, shoot multiplication, rooting and acclimatization of Petunia hybrida. Callogenesis from leaves of in vitro-grown seedling was observed on MS medium supplemented with 0.1 mg/l NAA combined with BAP at various concentrations (0.0, 0.25, 0.5 and 1.0 mg/l). The results indicated that the medium with BAP at 0.5 mg/l in combination with NAA at 0.1 mg/l resulted in the highest percentage for explants producing callus (40%). Callus was transferred to regeneration medium to study the effect of three types of cytokinins including BAP, TDZ and Kin at different concentrations (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mg/l). The results showed that BAP at 0.2 mg/l or TDZ at 0.2 or 0.4 mg/l induced the highest multiplication capacity (90%). Another experiment employed four MS basal salt strengths (full, ¾, ½ and ¼ MS) in combination with three concentrations of sucrose (20, 30 and 40 g/l). Full strength MS basal salt medium with sucrose (40 g/l) boosted multiplication performance. Multiplied shoots were studied for rooting ability. Applying sucrose at the lowest concentration (15 g/l) with full or ½ MS produced the highest rooting percent (100%), the highest number of roots (8.33) per shoot and the longest roots (12.03 cm). The well rooted plantlets were successfully acclimatized on different potting media including peat moss, vermiculite, clay and perlite where clay surpassed other growing medium mixtures with a 89% survival rate.

Effect of Rice Straw Mulching on Water Use Efficiency, Growth, Yield and Quality of King Ruby Grape under Surface Irrigation
New agriculture practices are required for developing water use efficiency. Mulching as a target for that goalhas not been adequately quantified. The aim of this work was to clarify the role of rice straw mulchingin reserving water under surface irrigation and quantify its application benefits on yield and quality of king ruby grape vineyard grown in Delta Nile of Egypt during 2017 and 2018 seasons. The experimental layout included six treatments T1, T3 and T5 for three irrigation regimes which introduced control or zero, 25% and 50% of restriction irrigation water. T2, T4 and T6 introduced the mulching application within the previous irrigation regimes. The irrigation regime started at veraison phase (pre maturity stage) from May 2017 till end of July (time of harvest) and straw mulches were applied at rate 5 kg/m2, and it was renewed in 2018 season. Soilbulk density (BD), infiltration rate (IR) and NPK uptake were looked up. Growth and qualities attributes were figured out as a reflection affect by treatments under investigations. Results highlighted the role of mulching in keeping soil moisture under severe drought stress, 50% of restriction irrigation water (T6) similar to unstressed, control (T1) subsequently the most measured parameter of soil, growth and quality were similar in both treatments. These findings suggest the application of T6 (50% of restriction irrigation water) treatment as a target recommendation for saving 50 % of irrigation water without yield reduction and with good qualities.

Correlation and Path Coefficient Analysis for Seed Yield and some of its Traits in Common Bean (Phaseolus vulgaris L.)
Common bean (Phaseolus vulgaris L.) is one of the most important vegetable crops grown in Egypt. This study was conducted to determine the phenotypic, genotypic, and environmental correlations between seed yield and some of its traits, and to perform path analysis to assessthe direct and indirect effects between seed yield per plant as dependent variable and the other traits as explanatory variables.Twenty-seven accessions of common bean were evaluated at El-Dalgamon village, El-Gharbia Governorate, Egypt during the two successive summer seasons of 2016 and 2017 using a randomized complete block designwith three replications.The results revealed the importance of genotypic correlations coefficients compared to the corresponding values of phenotypic ones. The genotypic correlations were positive ranging from 0.60 to 0.99 for the correlation between seed yield per plant and each of plant height, number of leaves per plant, number of days to flowering, number of racemes per plant, number of days to maturity, number of pods per plant,and number of seeds per pod. Genotypic path analysis indicated the importance of positive direct effects of plant height, number of pods per plant,number of days to maturity, andnumber of seeds per pod,suggesting thedirect selection of these traits to improve seed yield. Whereas, number of leaves per plant,number of days to flowering,ornumber of racemes per plant should be selected simultaneously with plant height ornumber of pods per plant since they had high positive indirect effects on seed yield through these two traits.

Effect of Calcium and Boron on Growth, Fruit Setting and Yield of Hot Pepper (Capsicum annuum L.)
Two successive seasons of 2017 and 2018 were conducted at the Experimental Station of the Faculty of Agriculture, Ain Shams University, Cairo, Egypt to study the response of hot pepper plant (Capsicum annuum L.) cv. Hot Chili growth, fruit setting, yield and some biochemical constituents linked with the yield and quality characteristics to foliar spraying with calcium chloride at 0, 1000 and 2000 ppm, boric acid at 0, 200 and 400 ppm and their combinations. Results indicated that all foliar applications of calcium chloride and boric acid treatments individual or in combination markedly increased the vegetative growth characteristics, fruit setting percentage and fruits yield of hot pepper plants. Foliar spraying with 2000 ppm of calcium chloride plus 200 or 400 ppm of boric acid treatments obviously gave the higher values of plant height, number of branches per plant, shoot fresh and dry weights, fruit setting, fruits yield/ plant and fruits yield/ feddan as well as total carotenoids, vitamin C and N, P and K concentrations compared to the check treatment in both tested seasons.

Quality Maintaining of Stored Cucumbers Under Cold Stress and Shelf Life at Room Conditions by Integrating Calcium Chloride and Short Hot Water
Cucumber fruits were impregnated inhot water at 55 oC for 5 min containing 0, 1 or 2% calcium chloride to study the effectiveness of the integration of calcium chloride and short hot water in prompting cold stress tolerance and quality maintenance of cucumbers during cold storage and room conditions. The quality attributes like weight loss, appearance, color, taste, chilling injury, firmness, soluble solids content, sugars and total phenolics, electrolyte leakage and antioxidant enzymes (peroxidase and catalase) were analyzed during cold storage for 7, 14 and 21 days at 4 oC and shelf life at room conditions for 2 and 4 days.The combined treatment of 1% calcium chloride andshort hot water (1%Ca+SHW) exhibited a significant synergistic enhancement in inducing chilling tolerance, degrading peroxidase activity, maximizing catalase activity and reducing electrolyte leakage. Likewise, a good appearance, better taste and color,less weight loss and highest firmness and total phenolicswere documented in 1% Ca+SHW treated cucumbers. SSC and sugars were preserved by inhibiting ripening and senescence processes in 1% Ca+SHW. In the light of this study, 1% calcium chloride in combination with short hot water as a commercial applicationcan be used to maintain quality,increase storability and extend cold storage of cucumbers at 4 °C and shelf life at room conditions or at the market and home.

Effect of Gypsum and Compost on Growth and Yield of Washington Navel Orange under Saline-Sodic Soils
INCREASING saline-sodic soils area as a result of climatic change, wrong agriculture practices and unsuitable of nutrition sources were lead to malnutrition and caused low productivity and quality of citrus. The study focused on gypsum and compost application in the proper rates for coping with such variable parameters. The trial carried out during 2017 and 2018 seasons on Washington navel orange trees (Citrus sinensis L., Osbek) grafted on sour orange (Citrus aurantium L.). Six application treatments were examined for the purpose of the study, i.e., T1: control, T2: compost at 10 tons / fed, T3: compost at 15 tons/ fed, T4: gypsum at 10 tons/ fed, T5: T4+T2 and T6: T4+T3. Field capacity (FC), Permanent wilting point (PWP), available water (AW), soil moisture and soil total content of NPK as indicators of soil parameter for application treatments were looked up. Growth parameters such shoot length, number of shoots/branch, number of leaves/shoot and leaf area, yield attributes such fruit set, fruit cracking, peel thickness, total tree yield (Kg), fruit juice volume, TSS, acidity, total sugars and vitamin C and leaf nutritional content of N, P, K, Ca and Mg were also determined. Results showed that T6 gave the highest results followed by T5, T4, T3 and T2 whereas T1 was the lowest ones for all parameters under investigations. The study aimed and recommends gypsum at 10 tons/ fed + compost at 15 tons/ fed for ameliorating saline-sodic soil and improving growth, yield and quality of Washington navel orange under such conditions.

Effect of Chitosan and Gibberellic Acid Applications on Yield, Quality and Yield Pattern of Globe Artichoke (Cynara scolymus L.)
A two-year study was carried out in Alexandria, Egypt to investigate the potential compensation of thermal requirement for artichoke flowering by gibberellic acid (GA3) treatment and to evaluate the effect of combined treatment of GA3 and chitosan. The experiment comprised twelve treatments, four treatments of GA3 at 0 (control), and 25 ppm, sprayed once, twice or three times at one month interval between treatment and three levels of chitosan at 0, 150 or 300 ppm. The effect of these treatments was evaluated on plant growth, earliness, productivity, quality and yield pattern of globe artichoke of the improved local El-Baladycultivar. The results showed that plants sprayed once or twice with GA3 gave the highest values of vegetative growth, early yield and edible part fresh weight. However, spraying artichoke plants three times with GA3 resulted in the highest number of heads / plant, total yield, average head weight, head diameter and edible part diameter. Moreover, spraying chitosan at 300 ppm significantly increased plant growth characters, head yield and its components. In addition, the interaction treatments between spraying artichoke plants two times with GA3 and chitosan at 150 ppm gave the highest values for early yield. However, total yield favored spraying plants three times with GA3 and 300 ppm of chitosan. The results showed that the percentage of yield pattern distribution for the plants treated three times with GA3 as average of both seasons, were 27.9 and 29.4 % compared to 25.6 and 27.4 % for the non-treated plants in both seasons, respectively. On the other hand, applying chitosan at 300 ppm gave 27.4 and 36.3 % compared to 24.2 and 26.7% for the control plants in both seasons.

Assessment of Variability and Response to Selection for Earliness and Curd Size in Cauliflower cv. soultani under Assiut Environmental Conditions
The present study was conducted during three consecutive winter seasons (2015 to 2017). Assessment of the variability and genetic associations within a population of the local cauliflower cv. Soultani along with the response to phenotypic positive mass-selection for days to visible curd (DVC) and curd diameter (CD) were studied. Further, field performance of concurrently evaluated base (C0) and both first (C1) and second (C2) cycle populations was conducted. Data analysis showed a wide range of variation in the primary (DVC and CD) and secondary (plant length PL, number of leaves NL, curd weight CW and total plant weight TPW). All traits had low negative correlation coefficients (rg) with DVC while they showed high positive values with CD. The response (R) of DVC to selection, as percent of mean, was low due to the existence of a predominant non-additive gene action. However, CD exhibited a moderate R to selection in C1 that declined in C2. The highest correlated response (CR) was for the CW in C1 but no appreciable R occurred in C2. Estimated indirect selection efficiency for all secondary traits was less than one. Concurrent field evaluation showed significant differences among the three populations (C0, C1 and C2). Relative to C0, the C2 population had 57% higher total yield and 114% early yield. The DVC showed a reduction of 11.7% and CD elevated 47.6%. We concluded that directive positive mass-selection can practically be efficient in improving our cauliflower landraces.

Alleviation of Cold Stress on Tomato During Winter Season by Application of Yeast Extract and Glycinebetaine
The main aim of the current study was to investigate the effect of yeast extract (YE) and glycinebetaine (GB) on mitigation of the low temperature stress in tomato plants cv. Basha 1077 F1 during the winter season. Sixteen treatments, four YE (0, 3, 6 and 9 g/L), four GB concentrations (0, 5, 10 and 15 mM) and their interaction, were applied and arranged in a randomized complete block design with a split plot arrangement with three replicates. The study results indicated that tomato plants positively responded to the foliar applications of YE and GB. It showed that increasing of foliar application of YE concentrations up to 9 g/l increased the vegetative traits (shoot fresh and dry weights, and root fresh and dry weights), yield traits (fruit weight, fruit weight per plant, total yield and marketable yield) and fruit quality traits (total sugars, TSS, vitamin C, carotenoids and lycopene content). Also, foliar application of GB at 5 mM significantly increased the vegetative growth, yield and fruit quality traits compared to the control and other GB treatments. Furthermore, foliar application of YE at 9 g/L along with foliar application of GB at 5 mM resulted in the highest values of the above mentioned traits. Moreover, this combination of treatments significantly increased the total chlorophyll content as well as peroxidase and catalase activity. The results of this study suggest use of YE and GB in commercial production of tomato where low temperature is likely.

Improvement the Productivity and Quality of Pelargonium× hortorum L. Plants by Using Potassium Iodide Applications
Iiodine has considered as a trace beneficial element for higher plants and it has long been recognized as an important element environmentally. In order to study the effects of different application methods (foliar spray, soil application or foliar combined with soil application) of potassium iodide (KI) at 2, 4, 6 or 8 mg L-1 on vegetative growth and some physiological characteristics of Zonal pelargonium (Pelargonium × hortorumL.) plants, a pot experiment was carried out during 2017 and 2018 at AL Mansoura Horticulture Research Station, Horticulture Research Institute, Agriculture Research Center, Egypt. The study showed thatgenerally all different applications had positive effects on the vegetative growth and inflorescence parameters except foliar application at 2 mg L-1 concentration. Soil application at 2, 4 or 6 mg L-1 showed the highest values of shoot length, number of branches and fresh and dry weight. Soil combined with foliar applications at 6mg L-1gave the highest number and neck length of inflorescences per plant. Additionally, the same application method at 4mg L-1 resulted in the highest diameter of inflorescences.All used iodine treatments increased significantly nitrogen, phosphorus and total sugars in pelargonium plants over control while, the total polyphenols content of pelargonium plants was decreased in comparison to control plants.The results refer to the possibility of using KI as soil application for improved the productivity and quality of pelargonium plants.

Flowering, Fruiting of Two Table Olive Cultivars “Olea europaea L.” Grown in Southern Egypt
Olive is an evergreen tree that is well adapted to hot and dry climate, but requiresspecific chilling units for flowering. Olive is grown for table usage and oil production that is known for its organoleptic properties and health benefits. The area of olive production is increased in the new cultivated land such as in south Egypt. The present study is conducted to evaluate the flowering behavior and fruit characteristics of two table olive cultivars (cvs.)’ Toffahi ‘and ‘Aggizi’ that firstly grown in southern Egypt (Qena) during seasons 2016 and 2017. The growth season began early in February as the flowering bud appeared. There was variation in floral behavior between the studied cultivars. ‘Toffahi’ cv. had significantly longer flowering shoot with higher number of inflorescence (IFC) compared to ‘Aggizi’ cv. The IFC in the top and middle of the shoots were longer than that in the base in both cultivars, however, the flower number per IFC located in the shoot top and middle was higher in ‘Toffahi’ than ‘Aggizi’ cv. Despite that there were significant differences in flower number/ IFC and perfect flower percentage between ‘Toffahi’ and ‘Aggizi’, the fruit set percentage was not significant. Although the initial fruit number per shoot was higher in’Toffahi’ than ‘Aggizi’, the dropped fruits number was higher that making the final fruit number per shoot not significantly higher. The fruit characteristics such as: weight, size, length, width, flesh/stone ratio, moisture and oil contents were similar to the typical known for both cultivars.
Our results showedthatbothtableolive cultivars ‘Toffahi’ and ‘Aggizi’were able to adapt the new condition andmaintained the regular floral behavior and good fruit characteristics, suggesting that these cultivars can successfully be grown under southern Egypt conditions.

Floral Behavior, Fruit Characteristics and Oil Quality of Some Olive Cultivars "Olea europaea L."
Olive consumption is increased around the world due to the organoleptic characteristics and medicinal values of its fruit and oil. To meet this demand, increasing the cultivated area of olive becomes essential in areas rather than the Mediterranean basin. In this respect, some olive cultivars (cvs.) ’Koroneiki’, ‘Dolci’, ‘Carotina’ and ‘Maraki’ were cultivatedat the Research Center of South Valley University, Qena. The objective of this study was to monitorand evaluate these cultivars’ adaptation under Qena environmental conditions. The flowering behavior, fruit set, fruit growth, and the oil qualityof these four cultivars were assessed for two seasons (2016-2017). The results showed that the growth season began two weeks earlier than usual for all cultivars. ‘Koroneiki’ cv. had highest number of panicles per shoot but lowest number of flowers per panicle compared to the other cultivars.Despite that, the initial fruit set was high in all cultivars, fruit retention was varied. ‘Koroneiki’ had higher number of fruit per shoot followed by ‘Dolci’, ‘Maraki’ and ‘Carotina’. The fruit weight and size were slightly lower than the typical known for all cultivars grown in other regions. ‘Maraki’ cv. had the highest percentage of oil followed by ‘Carotina’, ‘Koroneiki’ and then ‘Dolci’. The quality indexes of the oil were within the limits of the stander extra version olive oil for all studied cultivars. Our results revealedthat, each olive cultivar had regular morphological characteristics, fruit propertiesandoilquality, suggesting that these cultivars were able to adaptQena’senvironmental conditions and gave high quality virgin oil.
