The investigation was carried out to study the stability parameters for fruit yield and associated characters in bottle gourd. The material comprised d of nine parents, 36 F1 hybrids and one standard check. The environments were created by sowing the crop on the different dates at two different locations. The study revealed the presence of genotypes x environment interactions. The variation due to G x E (linear) was significant for all the traits indicating that major portion of G x E interaction were linear in nature an prediction of these traits was still possible. Based on the individual genotypes of adaptability, it is evident that three parental line and twelve hybrids recorded high mean performance along with non-significant deviation from regression. The hybrid Banswara Local x PSPL recorded below average regression coefficient (bi=1) while hybrid Long C-92374 and Udaipur Local-I x IC-92374 recorded above average coefficient indicating their better performance in poor and better environments, respectively. While, the parental line Banswara Local-I, Pusa Naveen and PSPL and nine regression coefficient around unity (bi=1) indicating their stability in varying environments.
