Методы маркер-опосредствованной селекции позволяют ускорить создание сортов картофеля, устойчивых к Y вирусу картофеля (YВК), путем интрогрессии генов устойчивости к YВК (Ry) из дикорастущих сородичей картофеля. Распространение Ry генов среди клубнеобразующих видов Solanum изучено недостаточно. Два маркера, фланкирующих гены экстремальной устойчивости к YВК, Rysto и Ryadg, были валидированы путем анализа сортов картофеля, исследованных создателями этих маркеров, а затем использованы для скрининга девяти дикорастущих видов Solanum. Помимо S. stoloniferum, маркер гена Rysto найден у S. papita, S. polytrichon, S. hjertingii, S. bulbocastanum, S. brachycarpum и S. cardiophyllum. Помимо S. andigenum, маркер гена Ryadg был обнаружен у S. demissum и S. stoloniferum. Однако только в случае S. stoloniferum и близкородственного вида S. papita присутствие маркера гена Rysto согласовалось с экстремальной устойчивостью к YВК.

The methods of marker-assisted selection accelerate breeding potato varieties resistant to potato virus Y (PVY) by introgressing genes for PVY resistance (Ry) from wild potato relatives. The distribution of the Ry genes among the tuber-bearing Solanum species has been scarcely studied. Two markers flanking the genes for extreme resistance to YBK, Rysto and Ryadg, are validated by analyzing potato varieties investigated by the originators of these markers, and then are used to screen nine wild Solanum species. In addition to S. stoloniferum, the Rysto gene marker is found in S. papita, S. polytrichon, S. hjertingii, S. bulbocastanum, S. brachycarpum, and S. cardiophyllum. In addition to S. andigenum, the Ryadg marker is detected in S. demissum and S. stoloniferum. However, only in the case of S. stoloniferum and related species S. papita, the presence of the marker for Rysto gene correlated with extreme YBK resistance.
