Abstract
The research results estimate the backcrossing of multispecies hybrids developed in the genetic resources laboratory at the Institute of Potato Growing of the National Academy of Agrarian Sciences of Ukraine, as well as at the Transcarpathian State Agricultural Research Station of the NAASU on the issue of resistance to potato blight. Artificial infection has been done by fungus inoculum Phytophthora infestans (Mont.) de Bary to multispecies hybrids of the intensively studied seedbed of 127 samples. A significant phenotype polymorphism of the samples’ resistance to the pathogenic agent has been determined. Furthermore, forms with high resistance to potato blight and economically valuable characteristics were singled out. Keywords potato, backcrossing of interspecific hybrids, resistance, blight, economically valuable characteristics.
研究结果估计了乌克兰国家农业科学院马铃薯种植研究所遗传资源实验室以及NAASU跨喀尔巴阡州农业研究站在马铃薯疫病抗性问题上开发的多种杂交品种的回交。用真菌接种疫霉菌(Phytophthora infestans (Mont.) de Bary)对127个样品的多种杂交种进行了人工侵染。已经确定了样品对病原菌抗性的显着表型多态性。此外，还筛选出抗马铃薯枯萎病能力强、经济价值高的品种。关键词马铃薯种间杂交回交抗性枯萎病经济价值特性
