For most quantitative traits in crop plants, genotype × environment interaction (GEI) is the rule rather than the exception. The best approach to cope with GEI is to exploit it by identifying genotypes best suited to specific environments so that the productivity in given environment is maximized. Fruit yield stability of 14 single cross hybrids of chilli across two seasons (summer and rainy seasons) over two years (2016 and 2017) was determined using AMMI and GGE bi-plots models at the Department of Genetics and Plant Breeding (GPB), Gandhi Krushi Vignana Kendra (GKVK), Bengaluru in randomized block design with two replications. Data were recorded on randomly chosen ten plants for fruits plant-1 and fresh fruit yield plant-1 and used to estimate AMMI stability value (ASV) and stability index (SI). GGE bi-plots were used as visual criteria for assessment of stability of hybrids. The results indicated that influence environments on the performance of hybrids for fresh fruit yield plant-1 and fruits plant-1 was greater than main effects of hybrids and hybrid × environment interaction. The hybrids, PC1 × CMS 6B and JL × PC1 were found to stable across seasons and expressed high mean performance for fresh fruit yield plant-1 and fruits plant-1, respectively. It is also evident that hybrids bearing single and pendant fruits were more often widely adapted than those bearing other types of fruiting habit.
