The use of codominant microsatellite molecular markers allows one to study the inheritance and distribution of alleles linked to important agronomic characters. A microsatellite locus WMS261 tightly linked to a dwarfing gene Rht8 was analyzed in wheat cultivars and selection material of the Institute of Plant Breeding and Genetics. PCR screening of common wheat cultivars produced in the southern Ukraine showed the prevalence of a 192-bp allele at locus WMS261 that indicates adaptive significance of a corresponding allele of the Rht8 gene in the southern regions.
共显性微卫星分子标记的应用使人们能够研究与重要农艺性状相关的等位基因的遗传和分布。在植物育种与遗传学研究所的小麦品种和选育材料中,对与矮化基因Rht8紧密连锁的微卫星位点WMS261进行了分析。对乌克兰南部生产的普通小麦品种进行PCR筛选,结果表明在WMS261位点192-bp等位基因占优势,这表明Rht8基因相应等位基因在南部地区具有适应性意义。
