Genetic variability studies in bottle gourd [Lagenaria siceraria]

Abstract

The study titled "Genetic Variability Studies in Bottle Gourd [Lagenaria siceraria] was conducted at the Experimental Department of Horticulture, Naini agricultural Institute (NAI), Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during kharif-2024-2025. The experiment was conducted in a Randomized Block Design (RBD) with three blocks and plant spacing of 2.5×0.50 m for 11 varieties. According to the experimental result from current study, bottle gourd varieties 2021/BOGVAR was found to be most suitable for Germination% 2021/BOGVAR-1(99.33). Day to first appearance of male flower in 2021/BOGVAR-5 (40.46), Days to first appearance of female flower in 2021/ BOGVAR-5 (46.67), Total no of male flower/ Plant 2021/BOGVAR-1 (48.67).Total no of female flower/ plant 2021/BOGVAR-1 (31.12) Days to first fruit harvest 2021/BOGVAR-9(15.67), Fruit diameter (mm) 2021/BOGVAR-4 (250.280) fruit length (cm) 2021/BOGVAR-2 (34.36).Vin length at last harvest2021/BOGVAR-1(4.80),Weight of individual fruit (g) 2021/BOGVAR-1(557.87).No. of fruits/plants 2021/BOGVAR-1 (8.00).
