【摘要】 用抗病亲本BJ399和感病亲本铭贤169配制组合,获得各世代材料。采用3个条锈菌生理小种(菌系)在温室条件下对BJ399进行苗期抗条锈性遗传分析。结果表明,BJ399对条锈菌生理小种(菌系)中4-1、CYR32和CYR34的抗病性均由1对显性抗性基因控制。BJ399可作抗源材料在甘肃陇南小麦抗锈育种中利用。更多还原

【Abstract】 The combination of disease-resistant parent BJ399 and susceptible parent mingxian 169 was used to obtain the materials of each generation. Three physiological strains(strains) of stripe rust races(or single spore strain) Zhong 4-1,CYR32 and CYR34 were used to analyze the resistance of BJ399 to stripe rust in greenhouse. The results showed that the resistance of BJ399 was controlled by one dominant gene to Zhong 4-1,CYR32 and CYR34,respectively. The wheat germplasm BJ399 could be used in wheat breeding in Longnan of Gansu Province.更多还原
