Abstract

The current study was carried out in the summers of 2021 and 2022 at the Main Experiment Station, Department of Vegetable Science, College of Horticulture and Forestry, ANDUA&T, Kumarganj, Ayodhya (U.P.), India, to evaluate the heritability and genetic advancement. Days to first staminate flower anthesis, node number to first staminate flower appearance, node number to first pistillate flower appearance, vine length, number of primary branches plant-1, fruit length, fruit circumference, average fruit weight, ascorbic acid, reducing sugars, total sugars, and fruit yield plant-1 were all noted to have high estimates of narrow-sense heritability in both the years and pooled data while, days to first pistillate flower anthesis, days to first fruit harvest in Y1 and pooled whereas, number of fruits plant-1 in Y2 and Pooled respectively. For the node number to first staminate flower appearance, node number to first pistillate flower appearance, vine length, number of primary branches plant-1, fruit length, ascorbic acid, reducing sugars, non-reducing sugar, total sugars, dry matter content in fruit, and fruit yield plant-1, high heritability as well as high genetic advance in percent of mean were recorded in Y1 and Y2, whereas in Y2 only number of fruits plant-1. In pooled dry matter content and reducing sugars showed high heritability as well as high genetic advance in percent of mean, indicating that simple selection based on phenotypic performance of these traits would be more effective as these traits were strongly influenced by additive gene action.

Conclusion

Days to first staminate flower anthesis, node number to first staminate flower appearance, node number to first pistillate flower appearance, vine length, number of primary branches plant-1, fruit length, fruit circumference, average fruit weight, ascorbic acid, reducing sugars, total sugars, and fruit yield plant-1 in both the years and pooled recorded high heritability estimates in narrow sense. In pooled high heritability along with high genetic advance in percent of mean were recorded for reducing sugars and dry matter content in fruit indicated simple selection based on phenotypic performance of these traits would be more efficient as these traits were strongly influenced by additive gene action.
