In the present investigation thirty sesame genotypes were evaluated for agro-morphological characters to study genetic diversity among newly developed genotypes. First six principal components with eigen value more than one contributed 81.02 % of cumulative variance. The thirty genotypes were categorized into four clusters using agglomerative hierarchical cluster analysis. Among the clusters, cluster I had the most genotypes (13 genotypes) followed by cluster III (11 genotypes) and cluster IV was monogenotypic. Charcoal rot leads to 5 to 60 % yield loss and is distributed in all sesame growing areas of India. The newly developed genotypes were screened for charcoal rot disease. Breeding lines viz., SES-S-19-2102, SES-S-20-3003, SES-S-20-2001 and 2 varieties CUMS-17, Swetha til recorded less than 10 % root rot infection and three moderately resistant lines viz., GT-10, SES-S-20-1038, SES-S-20-1039 recorded 10 - 20 % root rot infection. These resistant sources may serve as donor parents in hybridization programme for the development of disease resistant high yielding varieties in future crop improvement programmes. ICAR |
