Line x tester analysis for combining ability on yield and yield traits in elite breeding lines of brinjal (Solanum melongena L.)

Abstract

Thirty-six hybrids along with 15 parents (12 lines and three testers) were evaluated for combining ability in brinjal. On the basis of gca effects across eight characters, Punjab Neelam, DBSR-31, Ramnagar Giant, BR-SPS-14, ABSR-2 and Pant Rituraj were identified as most promising parents for inclusion in hybridization programme with the aim to improving fruit yield as well as other important yield and yield contributing characters. The most promising crosses showing high per se performance and significantly positive sca effects for fruit yield and some other important characters were Punjab Neelam x Dudhiya, Punjab Sanyog x Black Beauty, Arka Nidhi x Dudhiya, DBSR-31 x Pant Rituraj, Ramnagar Giant x Dudhiya, BR-SPS-14 x Pant Ritura, Azad Kranti x Dudhiya, Pusa Uttam x Dudhiya, ABSR-2 x Dudhiya, ABSR-2 x Black Beauty and Pant Samrat x Black Beauty. These crosses may exploit in the breeding programme for obtaining transgressive segregants towards developing hybrid varieties.
