Abstract

Twenty six genotypes as lines and two varities SVPR 1 and CO 1 of sesame (Sesamum indicum L.) were crossed in line x tester fashion and 52 Fts and parents were evaluated. Four characters were observed namely plant height, number of branches per plant, number of capsules per plant and seed yield per plant. The magnitude of SCA variances were more than GCA variances for all characters. It showed the preponderance of non-additive gene action including additive x additive. Fourteen lines namely SI 861, SI 1770, SI 2257, SO 573, IS 200, IS 207, IS 305, IS 534, RJS 2, BS 6-1-1, TSS 11, Paiyur 1, Gene 9101 and Thiruvellore local showed significant gca effect for seed yield per plant and also for yield components. Hence, these genotypes may be utilized for heterosis and pedigree breeding programme
