Determination of Genetic Diversity in Sesame

Abstract

The present investigation was carried out to identify eleven sesame lines during two successive seasons (2016 and 2017). The phenotypic variance (σ 2 ᵖ) was greater than the corresponding variance for all studied traits except capsule thickness. The genotypic variance and phenotypic variance values for number of capsules/plant and oil yield/fad., were high over the two years. High broad-sense heritability accompanied with high genetic advance was recorded for No. of branches/ plant, seed yield/plant and seed yield/fad. Five SSR primers were used for fingerprinting of the eleven sesame genotypes generated 19 bands, 10 of them were polymorphic with 53% polymorphism, N.A 554 produced one band negative marker in primer SSR1. Line 59-3-1 produced two band markers, one of them negative marker in primer SSR1 and the other positive marker in primer SSR5, while Line 82-7 produced one band positive marker in primer SSR5.

Genetic variability and selection criteria of some sesame genotypes for their agronomic traits and seed quality

“…This indicated that an increased influence of environment on these traits and thus the selection procedures involving progeny testing are recommended for these traits. Similar results were found by Mourad et al (2019), who recorded that the expected genetic advance ranged from 2.28% for standard germination to 22.31% for seedling dry weight. PCV: Phenotypic coefficient of variability, GCV: Genotypic coefficient of variability, h 2 b : Broadsense heritability, GA 5%: Genetic advance, GAM% of means: Genetic advance as percent of the mean.…”
