The experiment was undertaken on Line x Tester analysis for, grain yield and its component traits in crosses of A and R lines of rabi sorghum at All India Co-ordinated Sorghum Improvement Project, M.P.K.V., Rahuri, during the year 2017-18 with objectives to study the heterosis of parents and hybrids. The four CMS lines (females), ten testers (males) and their forty F1’s hybrids were studied by using L x T design. Observations were recorded on eleven characters viz., Days to 50% flowering, Days to physiological maturity, seedling height at 14 DAE (cm), Plant height (cm), Grains per panicle (no.), Panicle weight (g), 1000 grain weight (g), Dry fodder weight (g), Dry matter content (g), Grain yield per plant (g) and Harvest index (%). Among the eleven characters studied, majority of the characters exhibited mid-parents as well as better parent heterosis along with standard heterosis in desirable direction in most of the hybrids, indicating the predominant role of non-fixable inter-allelic interactions and over dominance in the expression of heterosis in respect of all these traits. Among the hybrids RMS-2010-16A x RSV-2124, RMS-2010-24A x RSV-2124 and CMS-185A x RSV-2124, are identified as promising crosses.
