| 摘 要： | 2006年和2007年人工接种鉴定云南省区域试验42份新品种对灰斑病、大斑病(northern leaf blight.NLB)、小斑病southem leaf blight,SLB)、弯孢霉叶斑病(Curvtdaria/leaf spot,CLS)、纹枯病(sheath blight,SB)、茎腐病(stem rot,SR)、穗腐病(ear rot,ER)、丝黑穗病(head smut,HS)、锈病(rust)等9种玉米病害的抗性,仅 海97-4能兼抗7种病害,占2.38%.7个品种兼抗6种病害,占16.67%.13份品种兼抗5种病害,占30.96%.能兼抗5种以上病害的品种共20份,占总数的47.62%.采用抗病基因类似序列(resistance stance gene analogue.RGA)分析,可把这42份品种划分为6个类群.第1类群,对弯孢霉叶斑病、丝黑穗病表现出抗性;第2类群.对灰斑病、丝黑穗病表现抗性;第3类群对弯孢霉叶斑病、茎腐病、丝黑穗病表现抗性;第4类群,对丝黑穗病、大斑病、小斑病表现抗性;第5类群对弯孢霉叶斑病、大斑病、小斑病病表现抗性;第6类群对大斑病、小斑病表现抗性. |

| Abstract: | In 2006 and 2007,42 new cultivars in the regional test in Yunnan were identified for their resistances to gray leaf spot(GLS),northern leaf blight(NLB),southern leaf blight(SLB),Curvularia leaf spot(CLS),sheath blight(SB),stem rot(SR),ear rot(ER),head smut(HS) and rust by artificial inoculation.Hai 97-4(2.38%) was resistant to 7 diseases,7 cultivars(16.67%) to 6 diseases,13 cultivars(30.96%) to 5 diseases,20 cultivars(47.62%) to more than 5 diseases.By using RGA data,the 42 cultivars were clustered into 6 g... |
