The experiment was undertaken on Line x Tester analysis for, juice yield and its component traits in crosses of A and R lines of sweet 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 CMS lines (females), ten testers (males) and their thirty F1’s hybrids were studied by using L x T design. Observations were recorded on fourteen characters viz., Days to 50% flowering, Days to physiological maturity, Internode / Plant, Plant height (cm), Stem girth (cm), Total biomass yield (t/ha), Cane weight (t/ha), Cane harvest index (%), Juice yield (lit/ha), Brix (%), Reducing sugar (%), Non-reducing sugar (%), Total sugar (%), Computed ethanol yield (lit/ha). Among the fourteen 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.
