The utilization of molecular markers at selected interspecific hybrids of Solanum species and for the assessment of wild Solanum species subcollection

Popis výsledku v původním jazyce

The selected wild Solanum species were chosen for crossing by means of traditional breeding methods. These wild species, maintained in genebank of Potato Research Institute in Havlíčkův Brod, are a good source of resistance to various biotic and abiotic factors. Hundreds of hybrids from many combinations, which were arisen by reciprocal crossing procedures (wild species x variety or dihaploid) and parental genotypes were tested by means of PCR methods. We obtained the crossing materials with wild species (S. acaule, S. berthaultii and S. demissum) with potato varieties. Hybridity of progeny after interspecific hybridization was visually checked by morphological traits and RAPD method. The hybridity was found at some hybrids from crossing combinations only. By means of PCR genotypes from seven wild species (S. acaule, S. berthaultii, S. bulbocastanum, S. brevidens, S. demissum, S. pinnatisectum and S. verrucosum) were tested. The plant material was transferred from in vitro conditions to the greenhouse and grown there. The DNA was isolated from these plants by means of GenElute Plant Genomic DNA Miniprep Kit (Sigma). DNA markers were chosen and tested. The selected markers were used for subsequent testing of diploid and tetraploid potato collections. The wild species bearing resistance markers are used for crossing experiments.
