Abstract:
An experiment was conducted to investigate yield and quality traits in germplasms of sesamum, in order to generate information regarding the extent of genetic diversity present in those germplasms. The experiment was laid out during kharif 2015 in 10×10 simple lattice design with two replications. The genetic diversity analysis revealed the formation of 10 clusters indicated the existence of sufficient genetic diversity among the germplasms. The cluster I contained 63, cluster II contained 15 germplasms, cluster V contained 10 germplasms and cluster VII contained 6 germplasms. While cluster III, IV, VI, VIII, IX and X possessed only one germplasm. The clustering pattern indicated that geographic diversity was not associated with genetic diversity. The analysis of per cent contribution of various characters towards the expression of total genetic divergence indicated that oil content followed by seed yield per plant, capsule per plant and seeds per capsule contributed maximum towards total genetic divergence. Based on the maximum genetic distance, it is advisable to attempt crossing of the genotypes from cluster VI with the genotypes of cluster X and cluster VII, which may lead to the generation of broad spectrum of favourable genetic variability for yield improvement in sesame.
