Opis:
New sources of Phytophthora infestans (late blight) resistance are studied in two groups of diploids: complex Solanum hybrids and clones of pure wild  Solanum species. In more advanced studies complex hybrids of Solanum verrucosum, S. phureja and S. microdontum were involved, which were intercrossed in various combinations. In this group, clones with resistance both in leaflets and tubers have been selected. In addition, highly resistant to late blight hybrids are outstanding in chosen quality traits. Resistance to P. infestans identified in the advanced hybrids has been successfully transferred into 4x level with various extent. The second group of sources recently included in research covers about 110 clones of five wild Solanum species (S. berthaultii, S. kurtzianum, S. michoacanum, S. ruiz-ceballozii and S. pinnatisectum). In 1999-2003 preselection of leaflets and tuber resistant clones was performed. Selected clones have been simultaneously characterized for male fertility and big pollen grains (2n) formation.

Opis:
A study on the expression of resistance to Phytophthora infestans of wild potato plants grown in a climatic chamber, in a screenhouse and in the field was performed in two experiments. In the first experiment 12 populations of Solanum acaule were tested. Detached leaves from field-grown plants appeared to be less resistant than detached leaves from chamber-grown plants. In the second experiment resistance responses to inoculation with P. infestans of 24 Solanum species, grown in the field and in the screenhouse were compared. In 18 populations belonging to 11 species the predominance of resistant plants was found either when plants were grown in the field or when plants were grown in the screenhouse. Within 12 tested populations no difference in resistance was observed because of high susceptibility of plants, irrespective of grown conditions. Two populations showed the same level of resistance under both grown conditions.
