Studies on Genetic Variability in Different Genotypes of French Bean (Phaseolus vulgaris L.)

Abstract

ABSTRACT-Genetic variability studied for eleven characters viz., number of leaves, branches, clusters, pods, pod length (cm), seed per plant, plant height (cm), 100 seed weight (g), days to flower, maturity and yield per plant (g) in group of forty two genotypes of French bean (Phaseolus vulgaris L.) revealed highly significant difference for all the characters. High heritability not only guideline for breeding improvement must to associated with genetic advance expressed a wide range of variability for all the traits. Heritability estimated and expected genetic advance were high for number of leaves (95.46< 97.00), branches (45.85 > 14.00), clusters (89.45< 92.00), pods (92.84< 99.00), pod length (88.94< 99.00), seeds per plant (92.20> 32.00), plant height (96.41< 106.00), 100 seed weight (99.22> 72.00), days to flower (94.82 > 32.00), maturity (56.26> 13.00) and yield per plant (80.13 < 140.00) suggesting that these are more useful traits for varietal improvement programme.

Character Association in French Bean (Phaseolus vulgaris L.) and Pea (Pisum sativum L.) A Review

“…of seeds /plant (70.93% & 73.83%), plant height (52.16% and 59.13%) and no. of pods (50.09% & 51.99%) highest GCV and PCV were recorded in forty-two genotypes (Topwal et al, 2016). Highly significant & positive association with germination percentage, plant height, no.…”
