Genetic Characterization for Quantitative and Qualitative Traits and its Relationship in French Bean (Phaseolus vulgaris L.)
An experiment comprising of thirty six diverse French bean genotypes were evaluated for genetic variability, correlation and path analysis for pod yield and its contributing traits. The analysis of variance was significant (p=0.01) for all characters indicated higher magnitude of variability. High heritability coupled with high genetic advance was recorded for the pod width, number of pods/plant, weight of ten pods, yield /plant and protein content. Total yield per plant was found to be positively and significantly associated with plant height, pod length, pod flesh thickness, number of seeds per pod, number of clusters per plant, number of pods per cluster, number of pods per plant, weight of ten pods. Positive association at genotypic level among the traits viz., number of clusters per plant, number of pods per cluster, weight of ten pods and pod length had exhibited true association with direct effect on yield per plant. The inter cluster D2 value was maximum (395.94) between cluster II and Cluster V indicating that these genotypes could be used in hybridization programme to obtain transgressive segregants.
