Abstract:
The field experiment was carried out by using twenty-six field bean genotypes to study the genetic variability, heritability and genetic advance. The characters studied were days to fifty percent flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, grain yield per plant (g), grain pod yield per plant (g). On the basis of mean performance, the genotypes, PYR 15-01, Nagavalli local 1 and Nallur local were found to be superior for yield and yield contributing traits. The genotype HA 3 was an early maturing type but which possess an optimal grain pod yield of 327 g/ plant. With respect to variability studies all the seven characters viz., days to fifty percent flowering, days to maturity, plant height, number of branches per plant, number of pod per plant, grain yield per plant (g) and grain pod yield per plant (g) recorded high value of PCV, GCV, heritability and genetic advance indicated the involvement of additive genes for the control of these characters and favours selection.
