Abstract

A field experiment was carried out with 42 genotypes of sesame (Sesamum indicum L.) at the Niger Research Station, Navsari Agricultural University, Vanarasi, Ta. Vansda. The study was performed to evaluate the genetic variability, characters association, path analysis and genetic diversity based on yield and yield related traits. The highest genotypic coefficient of variation was observed for seed yield per plant followed by capsules per cluster and harvest index. High estimates of heritability coupled with high genetic advance expressed as percentage of mean were observed for the traits viz., capsule width, capsules per cluster, leaf area, harvest index and seed yield per plant indicating that these characters are under the control of additive gene effect. The seed yield per plant was found to be significant and positively correlated with days to maturity, capsule length, capsule width, capsules per cluster, 1000 seed weight and harvest index at genotypic and phenotypic levels. The maximum direct effects as well as appreciable indirect influences were exerted by harvest index, capsule width, capsule length and 1000 seed weight. D2 analysis indicated wider genetic diversity among the forty-two genotypes which were grouped in ten clusters indicating there is no formed relationship between geographical diversity and genetic diversity. Cluster III and X showed the maximum inter cluster distance of 16.51. Hence, the genotypes belonging to the X, IX and VIII cluster could be used in hybridization program for obtaining a wide spectrum of variability among the segregants. Among different eleven traits studied, leaf area followed by capsules per cluster, harvest index, capsule width, seed yield per plant and capsule length contributed maximum towards the total genetic divergence. Results of mean cluster analysis showed that cluster X recorded highest cluster mean for four important yield attributing characters and cluster IX for two important characters. Genotypes from these cluster may produce progenies with high genetic variation.
