Abstract:

Seven lines, four testers and twenty eight F1 crosses derived through line x tester mating were evaluated to study the magnitude of heterosis for yield, water use efficiency and its attributing traits in order to assess the worth of a cross. The study on extent of heterosis revealed that sixteen hybrids out of twenty eight hybrids recorded high status with maximum score. The hybrid BL 862 × KKM 3 exhibited highest significant negative mid parent heterosis in desirable direction for days to 50 % flowering followed by BL 862 × VGG 4, Hg 19/A × NP 36 and LM 567 × KKM 3. The hybrid BL 866 x KKM 3 exhibited significant MP and BP heterosis for primary branches per plant, where as BL 862 × NP 36 showed significant mid parent heterosis for clusters per plant. BL 862 × GM 8413 (-7.31 %), BL 866 × VGG 4 (-6.21 %) and BL 862 × GM 8413 (-7.35 %), BL 866 × NP 36 (-6.69 %) showed significant negative heterosis over MP and BP for Δ 13C value, cross SML 134 × VGG 4 (51.75 %) revealed positive significant heterosis over better parent for SCMR, these may be useful in future breeding programs.
