Abstract

The experiment was conducted at three locations viz., Fedis, Babile and Gursum with the objective to identify chili pepper genotypes with high fresh pod yield and the most stable genotypes to different environments. To this end, 14 chili pepper genotypes, including the standard check were evaluated in a field experiment laid out in Randomized Complete Block Design with three replications, based on the GGE Biplot and mean, the genotypes FB-25, KW-14 and FB-26 had significantly higher fresh pod yield but higher regression coefficients indicated their suitability for favorable environmental conditions. The GGE Biplot also depicted the same result indicating genotypes FB-25 and KW-14 to be stable genotypes with lower IPCA 1 axis score, thus it had the lowest contribution towards the G×E interaction for fresh pod yield. The genotypes FB-25 and KW-14 were found to be generally adaptable for all the three different growing environments as compared to other genotypes. Therefore, the genotypes FB-25 and KW-14 were selected for their highest red pod yield and highest stability to the different environments under which the study was conducted. Therefore, these two genotypes were promoted to variety verification stage for possible release in the subsequent growing season.
