| dc.description.abstract | The present investigation entitled “Genetic divergence and stability analysis in Sesame (Sesamum indicum L.)” was carried out to estimate variability, broad sense heritability, genetic advance, correlation coefficient, path coefficient, genetic divergence and stability analysis with the objective of exploring possibilities of their commercial utilization. The material for the present study comprised of one hundred sesame genotypes selected from the available germplasms in Oilseeds Section. Sesame genotypes were evaluated in four environments i.e., Environment E1 (First fortnight of June, 2016), Environment E2 ( First fortnight of July, 2016), Environment E3 (First fortnight of June, 2017), Environment E4 ( First fortnight of July, 2017) during Kharif 2016-17 at the research area, Oilseeds Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. Data on five randomly selected plants from each genotype in each replication were recorded on different quantitative traits viz. days to flowering, days to maturity, plant height (cm), number of branches per plant, number of capsules per plant, number of seeds per capsule, capsule length (mm), capsule width (mm), 1000 seed weight (g), oil content (%) and seed yield per plant (g) in all environments. Base on Euclidean minimum distance, all the genotypes were grouped into eight clusters which showed the presence of enough amount of genetic diversity in the present material. The cluster II had the highest number of genotypes follow by cluster I, V, III and IV and other clusters having only solitary genotype. The intra-cluster distances were less than inter-cluster distances which showed that there was narrow genetic variation within clusters while there was maximum genetic variation between the clusters. Based on the comparative studies of the Eberhart and Russell (1966) stability parameters, each genotype only showed stability in some particular traits, none of the genotypes were found stable for all characters. The study resulted in eleven promising sesame genotypes. The genotypes KMR-41, NIC-7897, NIC-17921, IS-280, SI-982, TC-90, TC-169, EC-334952, S-0430, T-13-3-1 and HT-1 were found better and superior in stability for seed yield & its component traits and also oil content. | en_US |
