摘要: 在新疆伊犁地区1993年和1994年分别观察了195个和36个麦类品种对麦双尾蚜Diuraphis noxia(Mordvilko)的自然感虫性。36个品种两年的结果进行比较表明,感虫率级别相同的品种有18个,占50%;其中“一粒小麦”稳定地表现为不感虫性;感虫率稳定地表现在20%以下的品种有13个,即“86-2-4-2-3-3”、“京772”、“M85189”、“T579”、“永良13”、“T494”、“浮纳尔”、 “Mg4521”、 “广引74”、“Mg5824”、“Mg8586”、“T1008”和“短芒黑边红”; 感虫率稳定在20%~40%的品种2个,即“额敏黑芒”和“白长穗”; 感虫率稳定在40%~60%的品种2个,即“黑芒红”和“勾毛白”。其余品种,有14个两年的感虫率相差一个级别(20%);“黑芒长穗”、“高原602”、“伊宁黄库尔班”和“82-10-42-1-1”等4个品种感虫率相差二个或三个级别。另外,1996年塔城引种试验的2个品种“春麦雄性不育系901”和“啤酒大麦(石引1号)”均遭受麦双尾蚜的严重为害。

Abstract: During the investigation period in Ili Prefecture, Xinjiang Uygur Autonomous Region, 195 and 36 wheat varieties were accessed for their susceptibility to Russian wheat aphid (RWA), (Diuraphis noxia (Mordvilko)) in 1993 and 1994 respectively. Comparison of infestation grades among 36 wheat varieties by RWA in the two years showed that half of them were within the same grade. The aphid hardly attacked the “Onekernel wheat”, Triticum monococcum. 13, 2 and 2 of these varieties consistently showed low (<20%), middle (between 20% and 40%) and high (>60%) infestation rates by RWA respectively. However, there are 18 other varieties displayed obvious change in their infestation grades. In addition, the varieties “Spring Wheat 901” and “Shiyin1 of Beer Barley” being introduced into Tacheng were seriously infested by RWA in 1996.
