Eight BSSS and BSCB1 inbred lines of different cycles of selection were studied with the aim to evaluate which inbreds had the highest relative values of favourable alleles for the improvement of the grain yield trait in an elite single cross maize hybrid. Based on the estimated parameters microG, UBND, PTC and NI it was determined that the inbreds B73 (C5) and B84 (C7) originating from the synthetic population BSSS had the highest number of favourable alleles for the improvement of grain yield. The highest grain yield was recorded in the hybrid ZPL2 x B73, which also had the highest value of heterosis (174.9%) in the trial for estimation of loci relative values.
