ABSTRACT

Commercial exploitation of heterosis is feasible in maize due to floral morphology and high rate of cross pollination. Heterosis was estimated in 21 top cross derivates .The hybrid CML-269 X NM and CML-251 X NM exhibited significant and positive heterosis for grain yield over mid parent, better parent and checks, whereas, GWL-7 X NM, CML-286 X NM and CML-292 X NM showed significant heterosis for grain yield over mid parent, better parent and economic heterosis over check Narmada Moti. The desirable heterosis was also observed in the cross combinations of CML-269 X NM for days to 50 % tasselling, days to 50 % silking, ear height, days to 75 % maturity , ear length, ear girth, number of grain row per ear, number of grains per row, shelling percentage, 100-kernel weight and protein content.
