Abstract:
Sixty sesame genotypes including three checks, AKT-64, AKT-101 and PKV-NT-11 for eleven characters evaluated at three locations during summer 2018-19 to assess the seasonal genetic diversity present in the sesame germplasm based on the Mahalanobis D² statistics for the identification of genetically diverse and agronomically superior genotypes which may be further used in the hybridization programme. The pooled analysis of variance showed highly significant differences for all characters showing the presence of genetic variability. Clustering pattern indicated that grouping was not according to their origin. The Maximum intra cluster distance was found in cluster I (35.76) followed by cluster XII (35.64). The extreme inter-cluster distance was recorded between cluster XV and cluster XVI (243.36) indicating the maximum divergence between the clusters. Cluster XVI exhibited high mean value for number of branches per plant, 1000-seed weight, oil content and seed yield per plant. Oil content (25.14%) showed maximum contribution.
