已知方穗山羊草的抗叶锈菌基因Lr21和Lr22以及抗秆锈菌基因Sr33都已转移到六倍体小麦中.作者研究了1970年加拿大在伊朗收集的一个方穗山羊草的新样本RL549-1后,认为该新样本有一个基因对广谱的锈菌培养物具有抗性.它在二倍体中的抗性为部分显性,而在六倍体中,则因环境或呈部分显性或呈部分隐性.它的苗期抗性程度(按反应型说),在六倍体中较在二倍体
It has been known that both the leaf rust genes Lr21 and Lr22 and the anti-stomatal disease gene Sr33 have been transferred to hexaploid wheat.The authors studied a new sample of a Chinese goatgrass collected in Canada in 1970 After RL549-1, one new gene was considered to be resistant to a broad spectrum of rust cultivars, and its resistance in diploid was partially dominant, whereas in hexaploid it was due to environmental or Partially dominant or partially recessive.Its seedling resistance (according to the reaction type), in the hexaploid than diploid
