Abstract

Estimates of variability, heritability, genetic advance as percentage of mean and correlation were studied for 13 green pod yield and yield contributing traits in 43 indigenous and exotic strains of bush type French bean in randomized block design with three replications at Horticultural Research Centre, Patharchatta, Pantnagar, U.P. The range of various phenotypic and genotypic coefficient of variation, heritability in broad sense, expected genetic advance and genetic advance in percentage of mean were highest for green pod yield per plant. Green pod yield per plant was positively correlated with its maximum components except days to 50 % flowering, days to first green pod picking and number of nodes per plant, expressing higher phenotypic correlation than genotypic correlation as a result of environmental effects.
