In the first stage of the research as a result of hybridization domestic lines with genes Pi-l, Pi-2, Pi-33 were obtained. At the second stage – hybrids with all 3 genes were developed.

Существенно оптимизирует селекционный процесс применение молекулярных ДНК-маркеров, сцепленных с локусами резистентности. Цель исследований — получение линий риса с 2–6 генами резистентности к пирикуляриозу: Pi-1, Pi-2, Pi-33, Pi-ta, Pi-b, Pi-40 с помощью метода молекулярного маркирования. Донорами были иностранные сорта, реципиентами — российские. В исследованиях применяли микросателлитные маркеры и ПЦР-анализ. На первом этапе исследований в результате гибридизации получены линии с генами Pi-1, Pi-2, Pi-33. На втором этапе созданы гибриды, обладающие всеми тремя генами. На третьем этапе перенесены гены Pi-b и Pi-ta, на четвертом — Pi-40. В результате внутривидовой гибридизации получены и отобраны растения с шестью генами устойчивости к пирикуляриозу.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rice</kwd><kwd>donor</kwd><kwd>blast disease</kwd><kwd>resistance</kwd><kwd>hybrid</kwd><kwd>breeding</kwd><kwd>marker</kwd><kwd>PCR analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рис</kwd><kwd>донор</kwd><kwd>гибрид</kwd><kwd>пирикуляриоз</kwd><kwd>резистентность</kwd><kwd>селекция</kwd><kwd>ПЦР-анализ</kwd><kwd>SSR-маркер</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
