Genetic Variability and Heritability Studies in French Bean (Phaseolus vulgaris L.) under Tarai Conditions of Uttarakhand

Genotypic and phenotypic coefficient of variation, heritability in broad sense, genetic advance, genotypic correlation for 11 characters in 55 germplasms of French bean (Phaseolus vulgaris L.) were estimated during 2009 at Vegetable Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. Analysis of variation revealed significant differences among the genotypes for all the characters, high genotypic and phenotypic coefficient variation were observed for plant height (32.61 and 33.16) and lowest for days to 50 percent maturity (0.18 and 1.15). Heritability was found low in days to 50 percent flowering (12.72%) and high in plant height (96.66%) while genetic advance also varied from low to high for all the characters. High genetic advance was observed for pod length (15.46), pod yield per plant (45.69) and days to 50 percent maturity (50.26) and low for number of pod per plant (24.06). Correlation coefficient studies indicated that pod yield per hectare was positively and significantly correlated with seed yield per plant and 100-seed weight.
