摘要:

叶锈病和白粉病是世界范围内小麦上的主要病害,培育和种植抗病品种是防治这两种病害最经济有效的方法。为了明确1 200份小麦主栽品种(系)中抗叶锈病基因Lr21的分布情况,利用小麦抗叶锈病基因Lr21紧密连锁的分子标记对1 200份小麦主栽品种(系)进行检测,发现23个小麦主栽品种(系)中含有抗叶锈病基因Lr21。利用其他已报道的小麦抗叶锈病基因分子标记对23份小麦材料进行检测,发现藁优2018含有Lr20基因,矮丰8号、京冬22、中麦175、鲁原205和唐Y958含有Lr37基因,济南17含有Lr46基因,未检测到含Lr9Lr10Lr19Lr24Lr34的小麦品种(系)。分别利用小麦叶锈菌和小麦白粉菌流行小种对23份含有Lr21的小麦主栽品种(系)进行抗病性鉴定,7个小麦主栽品种(系)对叶锈菌和白粉菌同时表现抗性,出现频率为30.43%;6个小麦主栽品种(系)对叶锈菌和白粉菌同时表现感病,出现频率为26.09%。总之,筛选了含有抗叶锈病基因Lr21的小麦主栽品种(系),进一步明确了这些含Lr21的主栽品种(系)中其他抗叶锈病基因的存在情况,评价了它们对叶锈和白粉菌的抗性。

Abstract:

Wheat leaf rust and wheat powdery mildew are two important diseases in the world.Cultivating and planting disease resistant varieties is the most economical and effective method to control these two diseases.In order to test the distribution of wheat leaf rust resistance gene Lr21,the molecular marker closely linked to Lr21 was used to detect 1 200 wheat varieties(lines),and 23 wheat varieties(lines)were detected to contain Lr21.The molecular markers related to other leaf rust resistance genes were used to detect 23 wheat materials,Lr20 gene was detected in Gaoyou 2018,Lr37 gene was detected in Aifeng 8,Jingdong 22,Zhongmai 175,Luyuan 205 and Tang Y958,and Lr46 gene was detected in Jinan 17.No wheat varietie(line)was detected to contain Lr9,Lr10,Lr19,Lr24 or Lr34.Resistance evaluation of 23 wheat varieties(lines)containing Lr21 was identified using the epidemic races of Puccinia triticina(Pt)and Blumeria graminis f.sp.tritici(Bgt),respectively.The results showed that seven wheat varieties(lines)were resistant to both Pt and Bgt,with a frequency of 30.43%,and six wheat varieties(lines)were susceptible to Pt and Bgt mildew at the same time,and the frequency was 26.09%.Taken together,Lr21 was detected in 1 200 wheat cultivars(lines),as well as the presence of other rust resistance genes,and further evaluated their resistance to Pt and Bgt,which will provide a theoretical basis for the selection of multi-resistant wheat.
