Introgression from tetraploid durum wheat to diploid Aegilops longissima and Aegilops speltoides

Abstract

SummaryTetraploid to diploid introgression by means of interspecific triploid hybrids was followed in two species combinations:T. durum × Ae. longissima ABSl combination.T. durum × Ae. speltoides ABS combination.Triploids set rare seeds when exposed to massive back pollination by their diploid parents.Third-hybrid generation progenies of both combinations… (More)
