COLLECTION FORMATION AND USE

Abstract

The aim of the study was to investigate the collection of potato varieties in the southern part of Forest-steppe Ukraine and selection of samples resistant to viral diseases for further nd use in breeding work. The starting material was a collection of potato collection Ustimovka Experimental Station of Plant in the amount of 625 samples from 32 countries and abroad. For the biological status of the collection is represented by varieties. During research, it was found that the visual assessment of disease may be complicated due to some nonspecific symptoms that are similar to the symptoms of fungal and bacterial diseases of plants. Therefore, as a significant addition to the visual diagnosis of varieties has been used a wide range of virological methods for identification of viruses, which was carried out in the Laboratory of Ecology of viruses and viral diseases diagnosis "Institute of BioIogy" of the Taras Shevchenko Kyiv National University. Results virusologiche-ray studies confirmed the presence of viruses in infected plants. In the results, the study highlighted Tate samples that are recommended for further inclusion in the selection process: resistance to Potato leaf roll virus L – Кристал (Russia); Ada, Bzura (Poland); Sprint, Aguila, Roxy, Shwalbe, Tempora, Turbella, Apta, Kardula (Germany); Iskra, Galina (Czech Republic); Jaerla, Sante, Grata, Kardinal, Bintij, Ostara, Debora, Resy (Niderlany); resistant to mosaic virus wrinkly Potato virus Y + Potato virus X, Potato virus S, Potato virus A, Potato virus M – Kardula, Pamir (Germa-tion); Iskra, Galina (Czech Republic); Magura (Romania); Igor (Yugoslavia); Marijke, Desiree, Ostara, Debora, Radosa, Resy (Netherlands) and banded mosaic Potato virus Y – Perspective (Ukraine); Ada (Paul-sha); Sprint, Apta, Agwila, Augusta, Carla, Eros, Grata, Lori, Luna, Oda, Ponta, Shwalbe, Feldeslohn (Germany); Desiree, Ostara, Radoza, Saturna (Netherlands); Electre (Belgium); Maritta (France). These varieties are recommended for future inclusion in the selection process.
