The basic aim of maize breeding programs is the development of new hybrids that will
exceed the existing commercial hybrids. The purpose of this study was to estimate which
inbreds derived from the BSSS and BSCB1 populations had the highest relative values of
favourable alleles for the improvement of the number of kernels per row in an elite
maize hybrid. Inbreds B73 (C5), B97 (C9) and B99 (C10) had the highest values of
favourable alleles µG* for the improvement of the number of kernels per row. The inbred
line B73 (C5) originating from the synthetic population BSSS had a significant and positive
difference µG*-(µD* or µF*), hence in the breeding process, the F1 generation should be
crossed to an inbred donor and then self-pollinated to develop an improved inbred line.
Inbred lines B97 (C9), B99 (C10) and B84 (C7) had high values of µG* but did not have high
differences µG*-(µD* or µF*), not significantly higher than null. Ranking of inbreds as donors
of favourab...le alleles over four applied parameters (µG*, UBND, PTC and NI) shows
congruence. The best ranked inbred line B73 (C5) was the best over all four parameters,
while remaining inbreds expressed identical ranking confirming high and significant rank
correlations.
