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


, : Male fertility and freezing tolerance of hybrids involving Solanum tuberosum haploids and diploid Solanum species. Potato Research 39(3): 345-353

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.

The hybrid S. phureja 'WRF359.9' (diploid) x S. tuberosum 'US-W4' (haploid), designated US-W1109, was self fertile. Segregation ratios indicated that genes in US-W4 contributed self fertility to the hybrid by interaction with g...
