The objectives of our study were to (i) investigate changes in allele frequencies from progenitors of BSSS and BSCB1 to derived elite lines and examine especially the contribution of individual progenitors; (ii) compare the genetic diversity within and between the groups of progenitors and derived lines; and (iii) evaluate trends in genetic diversity among elite lines derived from early and advanced selection cycles.
