Open publisher page 7 citations

Abstract

Eighteen parents and forty-five crosses were evaluated for relative heterosis, heterobeltiosis and standard heterosis for yield and its components in a line x tester design. The hybrids viz BR-9 x Cavery, BR-10 x IR-8, Janki x Archana, Birsa Dhan-202 x Cavery and IR-36 x IR-8 were found as the best for exploitation of heterosis based on standard heterosis pertaining to grain yield per plant while the cross combination BR-10 x IR-36 and IR-36 x IR-8 showed highly significant standard heterosis for earliness, number of grains per panicle and panicle length apart from grain yield.
