Genetic variability, heritability and genetic advance studies in french bean (Phaseolus vulgaris L.) genotypes

Abstract

An experiment on evaluation in 36 genotypes of french bean was conducted at department of vegetable science, college of Horticulture, Bagalkot during rabi season of the year 2015-2016. The analysis of variance was significant (p=0.01) for all characters indicated higher magnitude of variability. Moderate GCV and PCV were observed for the traits plant height, number of primary branches, pod length, pod width, pod flesh thickness, number of pods / cluster, number of pods/ plant, weight of ten pods, number of root nodules/ plant, drymatter content of pods and roots. High heritability coupled with high genetic advance was recorded for the plant height, pod width, number of pods/plant, weight of ten pods, yield /plant, number of root nodules /plant, drymatter content of pods, roots and protein content. It indicated the presence of additive gene effects. Thus, there is an ample scope for improving yield and quality characters in french bean through direct selection.
