The G × E interaction makes it difficult to select the best performing as well as the most stable genotypes and so its efficient interpretation is important issue in plant improvement. The present study was carried out with objectives of to estimate the effect of genotype × environment interaction on the fruit yield and stability and estimate magnitude of genotype × environment interaction in bottle gourd. Forty five bottle gourd genotypes comprising 36 hybrids and 9 parents were evaluated in four different environments for stability parameters for days to opening first female flower, days to opening first male flower, number of node bearing first female flower, number of node bearing first male flower, vine length (cm), days to first picking, fruit length (cm), fruit equatorial diameter (cm), number of fruits per plant, average fruit weight per plant (kg), days to last picking and fruit yield per plant (kg). The analysis of mean squares due to genotypes and environments were found
Bottle gourd, G x E interactions, Stability
None of the parent was stable for fruit yield per plant, however, parents NDBG 132 and Arka Bahar were found to be highly responsive to better environments, while ABG 1 was found to be highly responsive to poor environments. Amongst the hybrids, ABG 1 × Arka Bahar, Punjab Long × NDBG 132 and Pusa Naveen × Samrat possessed more fruit yield per plant and had non-significant bi and S2di and thus, were considered as stable hybrids, needs to be evaluated at more locations before released as a hybrids for commercial cultivation.
