Abstract:
The present investigation was carried out with 24 French bean genotype during rabi 2009-10 in RBD having three replication at field experiment Centre of Department of Genetics and Plant Breeding, Allahabad School of Agriculture, SHIATS, Allahabad. The data were recorded on 13 quantitative characters to study the variability, heritability, genetic advance and correlation. Analysis of variance revealed considerable variability among the genotypes for all characters. All the 24 genotypes of French bean showed significant genetic divergence. Based on per se performance for seed yield per plant and other characters taken in consideration genotypes ET 8490 was found promising followed by IPR 96-4 and ET 8430.The characters like plant height, number of seeds per plant, harvest index and seed yield per plant exhibited high GCV, PCV, heritability and genetic advance should be given top priority during selection. The genetically more divergent genotypes present in cluster III and V may be utilized as parents in future hybridization programme to produce high yielding transgressive segregants. The grain yield exhibited positive and significant correlation with biological yield per plant, harvest index and test weight both at genotypic and phenotypic level. The large spectrum genetic variability in segregating populations depends on the level of genetic diversity among genotypes offer better scope for selection.
