Abstract

Twenty-eight non-reciprocal F1brinjalhybrids (Solanum melongena L.) obtained from eight

diverse genotypes were evaluated to estimate heterosis over better parent, mid parent and standard checks for eighteen commercial traits. Four hybrids (Pusa Purple Long × Black Beauty, Gulabi Long ×Surati Ravaiya, Pusa Purple Long ×Gulabi Long and Pusa Purple Long × Green Long) in long fruited segment and one hybrid each in round fruited (Black Beauty ×Surati Ravaiya) and small fruited segment (BB-44 × Black Beauty)were excelled in economic heterosis and showed 7.82 to 112.87 % heterosis over various standard checks.These six hybrids could be evaluated in multi-location and may be released for commercial cultivation as per adaptability to various agroclimatic regions. The pink fruit colour is dominant over purple colour, nevertheless recessive with dark purple and black colour.
