Abstract:
Enhancement of inbred parental lines in single cross hybrid is crucial for commercial success. Line recycling is a common procedure currently used in improvement of inbred lines in maize. The identification of favourable alleles in donor inbreds for improvement of single cross was given by Dudley. The objective of the present investigation was to evaluate four maize inbred lines to determine, which ones have the greatest relative values of favourable alleles for the improvement of ear length, number of kernels per rows and grain yield per plant (g) in the single cross hybrid (BML 6 × BML 7). The estimates of µG’ values revealed that out of the four donors, RSK 14 is superior in showing significant frequency of favourable alleles for the characters studied and it could be considered as the best donor for recycling of the BML 6 as it has great genetic affinity with the donor.
