The study aimed to find out a high yielding genotypes adapted to local environments and to study the genetic variability and relationships among yield, yield components and seed quality characters of 20 lentil genotypes. Giowing season significantly affected all characters except seed yield/fed. Seed yield averaged 494.31 kg/fed (3.09 ardab/fed). The genotype FLIP 95-67L had the maximum seed yield of 678.99 kg/fed (4.24 ardab/fed) and exceeded the yield of Giza 9 by about 29%. The genotypes FLIP 96-98L and XG 98/2/3 had the highest content of seed protein being 23.8% followed by Giza 9, Sinai 1 and FLIP 89-34L, with insignificant differences among them. Seed yield/fed was correlated positively and significantly with plant height, seed yield/plant, and number of pods and seeds/plant and hydration coefficient after cooking. Seed protein content was positively and significantly correlated with each of total soluble solids (r = 0.339), hydration coefficients before cooking (r = 0.301) and after cooking (r = 0.357). Despite no significant relationship occurred between seed protein content and seed yield, selection for high seed yield will indirectly increase seed protein yield. The highest magnitude of phenotypic coefficient of variation was observed for number of seeds/plant (30.23), seed yield /plant (26.69), seed yield/fed (24.04) and number of pods /plant (24.00) and 100-seed weight (20.18) indicating the possibility for effective selection for these traits.
