The Pm genes contained in wheat cultivars (lines) developed by Cytogenetics Institute of Nanjing Agricultural University in corporation with Lixiahe Agricultural Research Institute of Jiangsu Province and those from other sources were identified using RFLP markers tightly linked to Pm2 and Pm4a genes.
借助与 Pm2及 Pm4紧密连锁的 RFL P标记 ,对南京农业大学细胞遗传所与江苏省里下河地区农科所合作育成的抗白粉病小麦新品系及其它单位育成或引自国外但所含具体 Pm基因尚有异议的抗病品种进行了分析。
Since neither the seedling reaction of Pm3, nor that of Pm17, both lo cated on chromosome 1A, were as resistant as that of Little White Winter;and since none of the known Pm genes were loc.
由于1A染色体上的两个已知Pm基因Pm3和Pm17的苗期抗性均不如小白冬麦的强，也由于已知Pm基因中没有位于4D染色体上者，故认为小白冬麦和复壮30所含隐性抗白粉基因可能是新的Pm基因。
