Inbred lines derived through different cycles of recurrent selection of the synthetic populations
BSSS and BSCB1 were studied. The aim of the study was to evaluate which of observed inbreds
had the highest relative values of favourable alleles for the improvement of the elite hybrid.
The maximum G* allele values were detected in the inbreds B97(C9) and B99(C10)
originating from the populations BSCB1 and B14(C0) and B37(C0) originating from the
population BSSS. The observed inbreds derived from the synthetic BSCB1 were more related
to the parental inbred ZPL1, while those originated from BSSS were more related to the
parental inbred ZPL2. The significant differences between G* and D* were not established
in the inbred lines B97(C9) and B99(C10), hence the initial population for selection was derived
by direct self-pollination of F1 generation developed from the crosses of B99 × ZPL1 and B97
× ZPL1. The inbred B37(C0) was more related to the parental inbred ZPL2 and in that ...case
direct self-pollination could be performed from the cross B37 × ZPL2. Not only the G* values
were high in inbred lines B14(C0), B37(C5), B84(C7) and B91(C8), but also differences between
numbers of favourable dominant and unfavourable recessive alleles were significant. In this
case, in order to develop the initial population, backcross of the F1 generation (ZPL1 × Donor)
× ZPL1 is recommended for inbreds B84(C7) and B91(C8), while backcross (ZPL2 × Donor)
× ZPL2 is recommended for inbreds B14(C0) and B73(C5).
