RESULTS AND DISCUSSIONThe parents and inbred hybrids studied are rich in protein (8.08 to 11.34%), starch (59.78 to 71, 88%) and in oil (3.30 to 4.59%) and expansion by bursting was also observed very good up to 28.4 cc/g. Among the parents, I-07-63-36-1 showed good popping expansion of 25.4 cc/g also containing good amount of protein (10.02%), starch (64.91%) and oil (3.97%). In the case of the hybrid, I-07-63-1-2 x I-07-63-36-1 showed a high expansion of 28.2 cc/g with an increased amount of protein (10.54% ), starch (64.89%) and oil. (4.03%). The cross I-07-43-7-3 x I-07-35-7-3 had the highest oil content of 4.59%. The per se performance of the selected parents and hybrids is presented in Table 1. The analysis of variance for all traits studied was highly significant, indicating the existence of sufficient variation in the material studied. The dialle mating ANOVA showed highly significant estimates of GCA and SCA for all traits. The quadratic components associated with the SCA effect were greater than those of the GCA for all traits evaluated, revealing the preponderance of non-additive gene action for inheritance (Table 2). Similar results regarding the predominant role of nonadditive genetic action of traits have been matched for grain yield per plant, protein, starch, and oil content in normal corn (3); for days to flowering and maturity, plant height, grain yield, and burst expansion (22); for grain yield and shatter expansion (18); for plant height, grain yield per plant, and shatter expansion (9, 10). To exploit the vigor of hybrids, their performance per se, the extent of heterosis and the SCA effects of hybrids are important tools. The heterosis value with their magnitude and significance of the selected hybrids is shown in Table 3. The selection of hybrids...... middle of paper...... International (P) Limited, Publishers.17.
