Abstract:

Five maize inbred lines and their 10 direct crosses produced through half-diallel scheme were evaluated with two checks during kharif-2014 for grain yield and its component traits. The crosses namely JP25 W95 × CM-138 and CML-439 × CM-138 recorded higher level of economic heterosis for grain yield. Combining ability analysis suggested the preponderance of non-additive gene action for majority of the traits viz., grain yield, 100-kernel weight, ear length, ear girth and number of grain rows per cob. Out of the five parents, namely CM-138, CML-439 and JP25 W95 recorded significant general combining ability effects in desirable direction for grain yield and its component traits. The crosses JP25 W95 × CM-138 and CML-439 × CM-138 recorded significant SCA effects for grain yield and 100-kernel weight. The parents CM-138, CML-439 and JP25 W95 can be used for development of superior transgressive hybrids.
