Genotype × environment interaction studies in monoecious and gynoecious bitter gourd (Momordica charantia L.) genotypes for stability using multi-model based approach.

ABSTRACT: Bitter gourd is an important cucurbitaceous crop grown in the summer and rainy seasons. However, its improvement requires genotypes with high yield and stability across the seasons. We evaluated 22 (gynoecious and monoecious) lines across four environments (spring-summer and rainy seasons over 2 years) for number of fruits per plant (NFP), fruit length (FL), fruit circumference (FC), fruit weight (FW), and yield per plant (YP), with the goal of determining the genotype-by-environment interaction (GEI) for yield and yield-contributing traits. Analysis of variance indicated a highly significant variation among the genotypes, environments, and GEI for all the traits under study. The environmental influence on yield accounted for 70.38% of the total variation. The presence of a strong environm
