摘　　要：为了解甘肃陇南小麦育成品种和后备品种对当前条锈菌流行小种的抗性水平,利用条锈菌流行小种CYR32、CYR33和CYR34对60份供试小麦品种分别进行苗期、成株期抗病性鉴定。结果表明,在所有供试品种中,对CYR32、CYR33和CYR34表现苗期抗病的品种分别有9、22和10份,表现成株期抗病的品种分别有35、38和30份。结合苗期和成株期鉴定结果,对CYR32、CYR33和CYR34表现苗期感病而成株期抗病的品种分别有28、22和24份,占46.7%、36.7%和40.0%;中梁14号和兰天37号对CYR32、CYR33和CYR34均表现全生育期抗性,占3.3%。甘肃陇南麦区小麦品种对当前条锈菌流行小种多表现为成株期抗性,筛选出部分具有全生育期或成株期抗性的品种,可作小麦育种的亲本资源加以利用。To understand the resistance level of wheat varieties(lines)bred in Longnan of Gansu,60 wheat varieties(lines)were identified at seedling stage and adult stage with three current predominant stripe rust races CYR32,CYR33 and CYR34.The results showed that 9,22 and 10 of the tested materials were resistant to CYR32,CYR33 and CYR34 at seedling stage,respectively;And 35,38 and 30 of the tested materials were resistant to CYR32,CYR33 and CYR34 at adult stage,respectively.Base on the seedling and adult stage reactions,28,22 and 24 materials were resistant at seedling stage but susceptible at adult stage to CYR32,CYR33 and CYR34,accounting for 46.7%,36.7%and 40.0%,respectively.Zhongliang 14 and Lantian 37 were resistant at the all stage to CYR32,CYR33 and CYR34,accounting for 3.3%of the tested materials.The resistance of wheat varieties(lines)from the Longnan of Gansu to current predominant stripe rust races was mostly in the adult stage,and some varieties(lines)with at the all stage or adult stage,which can be used as parent resources for wheat breeding.
