Plasmons and male sterility types in Solanum verrucosum and its interspecific hybrid derivatives

摘要: Solanum verrucosum (2n=24) is easily crossable with many diploid species and haploids, but usually as a female partner only. All interspecific hybrids studied appeared male sterile due to interaction of S. plasmons genes from parents. Seven sterility types have been discovered in the investigations made on 21 introductions their hybrid derivatives. These are briefly discussed. proves possess at least four denoted [Trs], [Pss], [Svs] [nss]. Each produces diagnostic type presence specific plasmon-sensitive which widely spread. The role barrier gene exchange between populations
