Abstract

Harvesting time for seed as planting material plays a remarkable role in successful crop production, like in pumpkins. The study investigated the relationship between fruit weight and pulp firmness on seed attributes of two pumpkins (Thong Lanna 4 (TL4) and TL5) and determined which pumpkin is for flesh and seed production. Based on the Pearson correlation analysis, a pumpkin with a high fruit weight and pulp firmness contained a greater mature seed yield and mature seed count per fruit, observed 45 days after flowering (DAF). Late harvesting of pumpkins displayed heavier fruits with a higher mature seed count and mature seed yield per fruit, which was observed in TL4 and TL5. But TL5 showed these characteristics than TL4. However, earlier harvesting (35 DAF) of pumpkin fruit could be done in TL4 due to its higher mature seed count and mature seed yield per fruit than TL5. Late harvesting as 45 DAF displayed a more intense orange pulp color, heavier fruits, and higher total soluble solids in TL4 and TL5. The latter pumpkin could be harvested at 45 DAF, while 35 DAF for TL4 if the fruit weight and pulp firmness are considered. Thus, TL4 and TL5 can be harvested depending on their purpose, such as seed and flesh production.
