摘要

Combining ability studies using 10 x 10 diallel set (excluding reciprocals) were carried out at two locations (Hyderabad and Allahabad) and in two seasons (kharif 2003 and 2004) for grain yield and three quality parameters viz, protein content, oil content and tryptophan content. From this study, it was inferred that out of 45 hybrids studied, the cross combinations viz, P-4 x P-7, P-5 x P-10, P-2 x P-6, P-3 x P-5, P-3 x P-9 and P-1 x P-5 were found as good specific combiners for grain yield alongwith protein, oil and tryptophan content. Among the 10 parents, the parents P-3 and P(1)d were found to be the best parents for grain yield, while the parents P-4, P-7, and P-2 for protein, oil and tryptophan content.
