Abstract:
The present investigation was conducted at Raipur KVK Farms IGKV Raipur during the rabi season of (2021-22). The experiment was planned with the view to find out efficient time of pollination and fruit retention on seed yield and quality Parental Lines of cv Arka Vikram hybrid ridge gourd. The experiment was laid out in randomized block design with six treatments, repeated four times. Treatment T₃ (Pollination done 12 hours after anthesis + retained 6 fruits) reported significantly higher seed yield per plant (g), fruit yield per vine, fruit length and highest number of seeds per plant, higher percentage of seed germination, maximum seedling length and higher value of seed vigor index. The efficient time for pollinating the stigma for hybrid seed production of ridge gourd was found 12 hours after anthesis. For pre-harvest traits, number of days recorded for earliest flowering for both staminate and pistillate flower ranged from 38.9-45.8 days and 37.8- 42.8 days after transplanting. Treatment T₃(Pollination done 12 hours after anthesis + retained 6 fruits) and T₄ (Pollination done 12 hours after anthesis + retained 10 fruits) recorded early setting of fruits and highest fruit set percentage as compared to other treatments. The pollination done 12 hour after anthesis + retained 6 fruits recorded good quality hybrid seed of ridge gourd.
