Ушбу тадқиқотда буғдой навларининг сариқ занг касаллигига чидамлилигини аниқлаш мақсадида молекуляр маркерлар қўлланилди. Чидамли Avocet изоген линиялари ҳосилдор навлар билан чатиштирилиб, ҳосил қилинган беккросс авлодлар фенотипик ва генотипик жиҳатдан баҳоланди. Тадқиқот натижаларига кўра, Xpsp3000 ва Barc008 SSR маркерлари мос равишда Yr10 ва Yr15 чидамлилик генлари билан яқин боғлиқликка эга экани тасдиқланди. Ушбу натижалар селекция жараёнида маркерга асосланган танлов (МАС) технологиясини қўллаш орқали сариқ зангга чидамли янги навларни яратишда самарали ёндашув эканлигини кўрсатди.
