Genomic prediction of synthetic hexaploid wheat upon tetraploid durum and diploid Aegilops parental pools
Bread wheat (Triticum aestivum L.) is a globally important food crop, which was domesticated about 8–10,000 years ago. Bread wheat is an allopolyploid, and it evolved from two hybridization events of three species. To widen the genetic base in breeding, bread wheat has been re-synthesized by crossin...
