dc.description.abstractThe present investigation entitled “Genetic variability and correlation studies in fababean (Vicia faba L.)”, was carried out at the, Research area of MAP (Medicinal, Aromatic and Potential Crops) Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (Haryana, India) during Rabi 2015-16. The observations were recorded for different morphological characteristics and quantitative to assess the genetic diversity in 80 fababean genotypes. The observations were also recorded on 10 seed yield and its component traits for these genotypes to assess the genetic diversity. The GCV and PCV were observed highest for 100 seed weight, number of pods per plant, seed yield per plant, number of branches per plant and number of clusters per plant but lowest for days to maturity. High heritability coupled with high genetic advance for traits viz., days to 50% flowering, plant height, number of branches per plant, number of clusters per plant, pod length, number of pods per plant, 100 seed weight and seed yield per plant, indicated additive gene effects. Seed yield per plant had a positive and highly significant correlation with days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, number of seeds per pod and 100 seed weight. Path cofficient analysis indicated that 100 seed weight had the highest direct and positive effect on seed yield per plant followed by number of pods per plant, number of seeds per pod, days to 50% flowering, number of branches per plant, plant height. The direct negative effects were observed for pod length, clusters per plant and days to maturity. The hierarchical Euclidean cluster analysis grouped 80 fababean genotypes into seven clusters. The highest intra-cluster distance which was observed in cluster VI followed by cluster VII, cluster II, cluster V, cluster I, cluster III and cluster IV. A maximum inter cluster distance showed between cluster VI and cluster I which means that maximum genetic diversity is present between the genotypes of these two clusters. On the basis of mean values and divergence 14 genotypes viz. EC-591828, EC-628922, EC-628929, EC-628940, EC-628955, EC-628957, ET-3104, ET-3128, ET-3131, ET-3160, ET-4105, ET-4107, HB-82 and HB-85 were identified as promising for various characters showed sufficient amount of genetic diversity for seed yield and its component traits which may be used in fababean breeding programmes for further improvement.en_US
