 ABSTRACT

Identification of new sources of favourable alleles for improvement of elite single cross hybrid (P1 × P2) is one of the major goals in maize breeding programmes. The present investigation was carried out to identify the donor inbreds which have the greatest relative values of favourable alleles (μG') for the improvement the elite single cross maize hybrid DHM 117 (BML 6 × BML 7). The estimates of μG' values revealed that the donor inbreds BML 15 and BML 2 could be used as source of favourable alleles for improving elite hybrid with respect to yield and yield components. This improvement might be possible by transferring favourable alleles from BML 15 and BML 2 to BML 6 through back crossing as they had high genetic affinity with BML 6.

Key words: Maize, Favourable Alleles, Single cross hybrid.
