Abstract:

A 5x5 diallel analysis in F1 generation including reciprocals in Quality Protein Maize (Zea mays L.) inbreds revealed that GCA and SCA effects were significant for all the traits except plant height, ear girth and number of rows per ear. Reciprocal differences were highly significant for all the characters except plant height and ear length. The ratio of GCA to SCA showed the additive and non-additive types of gene action. For most of the characters, non-additive type of gene action was predominant. In the present study, among the parents, QPM 2-18, was found to be the best general combiner having highest GCA values for most of the traits followed by QPM 8-5 and QPM 3-7 and these might be used in the hybridization programmes for combining with poor general combiner like QPM 10-1 to generate superior segregants.
