Abstract
Thirteen genotypes of bottle gourd were assessed for stability parameters (Mean,
regression, coefficient and deviation from regression) for twenty two characters under three
environments during 2018-2019 at Haveli farm, College of Horticulture, Bagalkot.
The genotype × environment interactions were significant for vine length at 60 Days
after sowing (DAS), number of primary branches at 60 DAS, number of leaves at 45 DAS,
number of leaves at 60 DAS, days to first female flowers, node bearing first female flowers,
days to first harvest, fruit length, fruit girth and fruit shape index, average fruit weight, fruit
yield per vine, yield per plot and yield per hectare.
The genotypes Bot G-7 and Bot G-2 with higher mean values found stable for fruit
yield per vine, yield per plot and yield per hectare. For average fruit weight the genotypes Bot
G-7 and Bot G-2 were found stable. For fruit length the genotypes Bot G-7 and Bot G-6-1
were found stable. For fruit girth the genotypes Bot G-4 and Bot G-7 were found stable. The
genotypes Bot G-6 and Bot G-7 were found stable for fruit shape index. For vine length at 60
DAS the genotypes Bot G-7 and Bot G-2 were found stable. For number of primary branches
at 60 DAS the genotypes Bot G-7 and Arka Bahar were found stable. For number of leaves at
60 DAS the genotypes Bot G-7 and Bot G-2 were found stable. The genotypes Bot G-7 and
Arka Bahar were found stable for days to first female flower. For node bearing first female
flower the genotypes Bot G-7 and Arka Bahar were found stable. For days to first harvest the
genotypes Arka Bahar and Bot G-7 were found stable. The outstanding genotypes identified
for yield stability were Bot G-7 and Bot G-2 which can be exploited commercially.
