Abstract
Sesame (Sesamum indicum L.) was renowned in the ancient ages for the stability of its healthy oil, accessibility of extraction, and drought resilience. Consequently, to produce novel varieties, the present work entails the utilization of basic metrics of variability and genetic variation. The investigation included 60 sesame genotypes and 13 quantitative characteristics. The analysis of variance revealed that genotypes were significant for all of the parameters assessed (P>0.05 and P>0.01). The average seed yield per plant was 6.93g, ranging from 4.84 to 9.17g. In all of the traits studied, the phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variance (GCV). The tense relationship between PCV and GCV values indicated that the environment had minimal impact on the expression of the traits under investigation. The no. of branches, no. of capsules/axil, capsules per plant, no. of seeds per capsule, and oil content suggested higher estimations of PCV and GCV. The heritability varied from 75.13% for seed width to 99.03% for no. of capsules/axil. The genetic advance (GA) percent means varied from 7.71 (seed length) to 110.93 (no. of capsules/axil) at 5% selection intensity. plant height, no. of branches, 1000 seed weight, capsule length, capsules per plant, no. of seeds per capsule, seed thickness, oil content, and seed yield per plant all showed substantial heredity and a high GA% mean. Because of this, the traits of additive genetic control and direct selection in sesame have a high potential for increasing its yield.
