The present study was conducted on bottle gourd [Lagenaria siceraria (Mol.)Standl] genotypes for growth and yield parameters under open and protected conditions during 2017-2018.The experiment was laid out in randomized block design with three replications.Eight different genotypes Punjab Komal, Punjab Round, PSPL, Chutki, Vardan, Ankur Amit and Gopika were evaluated under open and protected conditions for growth and yield characters. Results revealed that in open field condition genotype Punjab Round found superior in respect of average fruit weight (933.33 g) and fruit yield per ha (60.62 t).PSPL takes minimum days to male flower (56.22) and minimum days to female flower (59.11) among all the genotypes.Genotype Nandani exhibit maximum plant height (7.51 m) and no. of fruits per plant (13.00).Whereas under Protected Conditions genotype Punjab Round was found superior in plant height (6.43 m), average fruit weight (926.13 g) and fruit yield per ha (359.80 t).PSPL exhibits maximum no. of fruits per plant (18.20).Minimum days to first male (49.40) and days to first female flower (58.41) was recorded in genotype Vardan.Among all the genotypes PSPL and Punjab Round showed superiority under both the conditions for most of the traits.So, they can be used for further research programmes as well as to develop the new hybrids and also recommended to farmers for off-season cultivation as well.
