Abstract

Genotypic variability, heritability and genetic advance expressed as percentage of mean for yield and its component were studies in twenty five genotypes of french bean collected from different sources and maintained in the Department of Applied Plant Science (Horticulture) under the School for Bio-sciences and Biotechnology, Babasaheb Bhimrao Ambedkar University Vidya-Vihar, Rae Bareli, Road, Lucknow (U.P.) India, were evaluated for various quantitative and quality traits. The material showed wide range of variability for green pod yield per plant (91.50-248.09q/ha), green pod yield per plant (54.91-148.87g), plant height (34.47-128.21cm), germination percent (68.87-100) and protein (17.09-30.38). The genotypic and phenotypic variances were high for 100-seed weight (43.11-43.22g) and plant height (40.92-41.71g). Heritability was high for 100-seed weight (99.50%) and plant height (96.50%) whereas it was lowest for green pod breath (26.80cm), high heritability combined with high genetic advance expressed as percentage of mean for 100-seed weight (88.59%), plant height (82.72%) and green pod yield q/ha (54.01%). The characters like 100-seed weight, plant height, green pod yield/plot, green pod yield/plant and green pod yield (q/ha), showed high genotypic coefficient variation and phenotypic coefficient variation with genetic advance, indicating there by that selections based on phenotypic performance could be effective for improvement of these characters.
