The results of interspecific potato hybrids evaluation using marker-assisted, laboratory and field methods

Abstract

Abstract The evaluation of interspecific potato hybrids was carried out in 2018–2019 in Moscow region and Krasnoyarsk region. Using the methods of traditional and marker-assisted selection the interspecific hybrids created at the Scientific and Practical Center for Potato and Horticulture in Belarus were screened. According to the results of molecular genetic analysis, forms with complex resistance to a potato cyst nematode, Y, X viruses were identified: 110xy 0911-19, 89y 06-2a, 38dy-39d, 71-10-10, 212-216-9, KC 211xy 04 -10, 18-06-2, 54-10-3. As sources of economic characteristics, interest in practical selection is represented by samples with a high starch content in different ecological zones: 201.161-11, 213.24-31, 60-10-6, 53-10-5, 2011 14-8; pollen fertility: 201.206-48, 201.13-11, 001125-43; resistance to Phytophthora infestans : 89y 06-2a, 18-06-2, 106y 07-22, 209.3-1, 201.13-11, 60-10-6, 54-10-3 etc.; high marketable yield, mass ofgrocery-ware tuber: 106y07-22, 201.13-11, 110xy 0911-19, 89y 06-2a, 38dy-39d; favorable chemical composition for processing on potato products, chips, fries: 213.24-31, 213.11-32, 201.13-11, 89y 06-2a, 18ay 10-2.
