This investigation was carried out to identify eleven sesame lines during two successive seasons, 2011 and 2012. Results revealed that line 117-7 surpassed the other genotypes in plant height, length of fruiting zone, number of capsules/pl., seed yield/pl., oil yield /fed., accelerated ageing germination and crude protein, while, line 112-5 gave the maximum estimates for number of branches/pl. and crude oil. Line 111-6 recorded high seed yield/fed. and seedling dry weight. Line 117-1 has the highest germination percentage, seed vigor index, shoot length and seedling vigor index. The total unsaturated fatty acids ranged from 85.02% to 87.31%. Meanwhile, total saturated fatty acids ranged from 13.41% to 15.46%. High estimates of (PCV) and (GCV) were exhibited for number of branches pl-1, number of capsules pl-1 and seed yield pl-1. The high heritability was exhibited for number of capsules pl-1, weight of 1000 seeds, seed vigor index, accelerated ageing germination, electrical conductivity µScm-1g-1, Seedling fresh weight and Seedling dry weight, so, selection could be effective for these characters. Heritability h2b was 70% at crude oil, 75% in crude protein and 87.51 % in total carbohydrate so; selection would be relatively effective for these traits. Randomly amplified polymorphic DNA (RAPD) analysis used to test the genetic diversity which generated a total of 52 DNA fragments, out of them 43 bands (82.7%) were polymorphic and high level of polymorphism was detected among sesame genotypes. RAPD-PCR was found to be useful as genotypes unique markers. The highest similarity was 88% between line108-6 and line111-4, While, line111-6 was genetically distant from line117-1 (similarity index 56%).
