Combining ability studies through line X tester analysis in sesame (Sesamum indicum L.)

Abstract

An attempt was made to study the general and specific combining ability in sesame (Sesamum indicum L.) through L X T analysis with seven lines and three testers. Seven characters viz., plant height, number of branches per plant, number of capsules per plant, capsule length, number of seeds per capsule, 1000 seed weight and seed yield per plant were studied. Based on the general combining ability effects of parents and per se performance, the genotypes FFAT0841, SVPR1 and FFAT0820 have considerable potential and can be utilized for developing cultivars, with high yield by using appropriate breeding strategy. Based on sca effects, the hybrids FFAT0818 X TMV6, FFAT0845 X SVPR1 and FFAT0831 X CO1 were adjudged as better hybrids for yield and yield component traits and hence recommended for yield improvement.
