Taub.) mutant lines for yield and yield attributing traits JF - <i>Electronic Journal of Plant Breeding</i> JA - EJPB VL - 12 IS - 3 SE - Research Article DO - UR - https://ejplantbreeding.org/index.php/EJPB/article/view/3971 AB - Fifteen cluster bean genotypes including the parent MDU 1 and fourteen determinate M5 generation cluster bean mutants were evaluated to determine the correlation and path analysis among yield and yield attributing characters. The genotypic correlation coefficient was observed to be higher in magnitude than the phenotypic correlation coefficient for most of the characters studied. The correlation analysis indicated the positive association of pod yield per plant with plant height, number of clusters per plant, total number of pods per plant, pod length, pod girth, pod weight, days to last harvest and number of seeds per plant. The path coefficient analysis indicated that the number of clusters per plant exhibited a very high positive direct effect on pod yield per plant at the genotypic level. ACMC-020-10 was identified as the best determinate mutant of MDU 1.Key words: Cluster bean, Correlation coefficient, Non-lodging, Path analysis ER -
