Twenty-seven winter wheat cultivars registered in the Czech Republic were tested by molecular markers for the presence of Lr26 and Lr37, and twenty-eight cultivars for the presence of Lr10. Gene Lr37 ...
摘要利用1套从小麦纯系和黑麦自交培育出的1R附加系、代换系和易位系，研究了1RS上的 抗叶锈基因Lr26在小麦中的表达。结果发现，1R二体附加系和纯合1RS/1BL易位系高抗小麦 叶锈病；而其小麦亲本、1R(1B)代换系和1BS/1RL易位系重感叶锈病。这一结果指出了黑麦 染色体臂1RS上的抗小麦叶锈病基因Lr26在小麦中的表达受小麦染色体臂1BL上的基因的强烈 影响，指出了外源基因在小麦中的表达...
