在26个小麦品种和20个大麦品种上,对采自陕西、青海和河南的10份大麦条锈病菌标样进行了致病性测定。除陕西的2份标样被鉴定为小麦专化型条中29号小种外,其余来自3省的8份标样均属大麦专化型。首次发现并证实了条形柄锈菌大麦专化型(Pucciniastriiformis West.f.sp.hordei)在中国西藏以外地区的分布,并确认大麦上发生的条形柄锈菌可以是大麦专化型,也可以是小麦专化型。
On 26 wheat cultivars and 20 barley cultivars, pathogenicity tests were carried out on 10 stripe rust barley samples collected from Shaanxi, Qinghai and Henan. Except Shaanxi 2 samples were identified as wheat specialization of the 29th species, the remaining eight samples from 3 provinces belong to barley specialization type. The distribution of Pucciniastriiformis West.f.sp.hordei in the areas outside Tibet of China was first discovered and confirmed. It was confirmed that the occurrence of P. tabaci in barley could be that of barley specialization, Wheat can also be specialized type.
