Genetic variability, correlation and path analysis for seed yield and yield related traits in french bean (Phaseolus vulgaris L.) under Lucknow conditions.

Abstract

Twenty five genotypes of French bean were evaluated to ascertain genetic parameters of variability, heritability and genetic advance in French bean was studied during rabi season involving 25 genotypes showing wider variation for all traits result revealed that highest range of variation was reported with green pod yield (q/ha) followed by green pod yield/plant (g). The coefficient of variation was minimum days to 50% flowering followed by days to first flowering whereas under pooled data analysis, it was found minimum for 100-seed weight followed by days to 50% flowering. In all the three studies, coefficient variation was maximum for leaf width (cm) and green pod yield/plot (kg). In the first year, heritability estimates were high for all the characters except 100-seed weight (g), plant height (cm) and number of pods/plant, whereas in the second year 100-seed weight (g), plant height (cm), moisture (%), number of pods/plant, green pod yield (q/ha) and number of leaves/plant attained lower heritability values. Under pooled data analysis, 100-seed weight (g), plant height (cm), moisture (%), number of pods/plant, green pod yield (q/ha) and green pod yield/plant (g) were found with lower heritability estimates. High heritability with high genetic advance were found with 100-seed weight (g), plant height (cm), green pod yield/plant (g) and green pod yield (q/ha).
