    Five chili genotypes were evaluated for two years at three locations to evaluate the performance and yield stability. Stability differences were assessed based on linear regression of the genotype on environmental index. Subsequently, the genotype by environment interaction (GEI) was analyzed using the AMMI statistical model. The combined analysis showed that fruit yield over six environments ranged from 21 to 33 q/ha with overall mean yield of 26.8 q/ha and genotype PBC-586, PBC-142A and PBC-401 gave the highest mean yield above the grand mean. The combined analysis of variance showed significant (p<0.05) genotype and genotype by environment effects on total fruit yield. The regression coefficient for fruit yield ranged from 0.77 to 1.2. The regression coefficient of the two high yielding genotypes (PBC-586 and PBC-142A) was above 1, and their performance was high in high yielding.. View More»
