2015年采用田间人工接种法,对25份小黑麦品种(系)进行了由大麦黄矮病毒(Barley yellow dwarf virus,BYDV)引起的小黑麦黄矮病的田间抗性鉴定和评价。结果表明,在供试的25份小黑麦品种(系)中未检测出免疫、高抗和抗病材料。有4份材料(农41、1519、1529和41)表现为中抗(MR),占供试材料的16.00%;12份材料表现为感病(S),占供试材料的48.00%;9份材料表现高感(HS),占供试材料的36.00%。将25份小黑麦品种(系)进行聚类分析,可划分为3类,从谱系图上可以看出,抗病性相同的品种(系)大致划分在同一个类中。

[Abstract]
In 2015, field artificial inoculation was used to identify and evaluate the resistance of 25 triticale cultivars (lines) to barley yellow dwarf virus (BYDV). The results showed that no immune, high resistant and disease resistant materials were detected in 25 triticale cultivars. Four materials (Nong 41, 1519, 1529 and 41) were moderate resistant (MR), which accounting for 16.00% of 25 triticale cultivars (lines); 12 materials were susceptible (S), which accounting for 48.00% of the tested materials; and 9 materials were high susceptible(HS), accounting for 36.00% of the tested materials. The clustering analysis result showed that 25 triticale cultivars (lines) can be classified into three groups. The cultivars (lines) with the same disease resistance were roughly classified into the same group.
