RAPD analysis of the interspecific somatic hybrids: Solanum bulbocastanum (+) S. tuberosum.

The diploid Mexican species S. bulbocastanum (blb) was used as a source of late blight resistance in somatic hybridization with the potato (S. tuberosum, tbr) dihaploid H-8105.

Resistance to Phytophthora infestans in somatic hybrids of Solanum nigrum L. and diploid potato.

In breeding for resistance to late blight, ( Phytophthora infestans Mont. de Bary), an economically important disease affecting potatoes, the search for new sources of durable resistance includes the non-host wild Solanum species. The aim of this work was to evaluate the resistance to P.

Somatic hybrids Solanum nigrum (+) S. tuberosum: morphological assessment and verification of hybridity.

Somatic hybrids between the cultivated potato diploid hybrid clone, ZEL-1136, and hexaploid non-tuber-bearing wild species Solanum nigrum L. exhibiting resistance to Phytophthora infestans were regenerated after PEG-mediated fusion of mesophyll protoplasts. The objective was to transfer the late-blight resistance genes from the wild species into plants of the cultivated potato clone.
