Male fertility and freezing tolerance of hybrids involving Solanum tuberosum haploids and diploid Solanum species

Potato Research 39(3): 345-353

Male fertility and freezing tolerance of hybrids involving Solanum tuberosum haploids and diploid Solanum species

Male sterility of (haploid x species) hybrids often hampers the exploitation of wild Solanum species in breeding for cold tolerance. In a study aimed at finding ways round these problems, it was noted that one accession of the cold tolerant wild species S. sanctae-rosae gave progenies segregating for male fertility in crosses with S. tuberosum haploids.
