Abstract:

Tetraploid to diploid introgression by means of interspecific triploid hybrids was followed in two species combinations: (i) T. durum × Ac. longissima ABS1 combination. (ii) T. durum × Ac. speltoides ABS combination. Triploids set rare seeds when exposed to massive back pollination by their diploid parents. Third-hybrid generation progenies of both combinations were diploid 2n = 14 or almost diploid 2n 15 or 16, with high fertility, and bore a close morphological resemblance to their respective diploid parent. © 1974, The Genetical Society of Great Britain.
