Genotype x environment interaction and stability analysis for grain yield in blackgram (Vigna mungo L.)

Eleven genotypes of blackgram were tested at three locations viz. Dharwad, Bidar and Gulbarga that represented different agro-climatic conditions of North-Karnataka during kharif 2009 to study their yield stability. Pooled analysis of variance and stability analysis were performed. The genotype (G)...

Summary:Eleven genotypes of blackgram were tested at three locations viz. Dharwad, Bidar and Gulbarga that represented different agro-climatic conditions of North-Karnataka during kharif 2009 to study their yield stability. Pooled analysis of variance and stability analysis were performed. The genotype (G) x environment (E) interaction and both variance due to genotypes and environments were significant. The partitioning of G x E interaction into linear and non-linear components indicated that both predictable and unpredictable components shared the interaction. On the basis of stability parameters, the top yielding genotypes, K-7-7 (1050 kg/ha) and DU-1 (1024 kg/ha) exhibited the stable performance over the locations. Results also revealed that the genotypes; BDU-3-3, T-9 and DU-3 also gave higher yield. But their performance was unpredictable due to high deviation from regression.
