Abstract:
Thirty-five advanced mutant lines of French bean (Phaseolus vulgaris L.) along with one commercial check were evaluated in Randomized Complete Block Design (RCBD) with two replications during Kharif 2017-18 at College of Horticulture Bengaluru. Genetic variability, heritability and genetic advance as percent of mean for 20 characters were assessed by field evaluation for all the characters were considered for the study. The analysis of variance indicated presence of significant variability among the genotypes for all the characters. Phenotypic and genotypic coefficients of variation for most of the traits were found moderate to high except for protein content per cent. High heritability along with high genetic advance over mean (GAM) was observed for pod width (cm), followed by pod yield plot (kg) and number of pods per cluster indicating that these traits could be exploited for further improvement through selection procedures. Most of the vegetable traits recorded higher variability among the mutants.
