Abstract:

In order to improve the seed yield of bottle gourd varieties (Zhepu 6 and Zhepu 9), the effects of different parent sowing dates, planting density and fruiting node position on seed yield were explored. The results showed that the female parent should not be sown later than the male parent during seed production of Zhepu 6, and the female parent should be planted close together, and the best distance between plants was 40 cm. The female parent of Zhepu 9 gourd should be sowed 10 days earlier than the male parent, and the planting density should be 40 cm, the fruiting node position should be a low node (7-8 nodes of the subvine). After implementing these cultural practices, the yield of seed production can be significantly improved.

Key words: bottle gourd, seed production, parental sowing date, density, fruiting node position
