| 摘 要： | 研究比较分析了“青华矮6号”等水稻抗病新品种对我省稻白叶枯病〔Xan-thomonas campestris pv.orvzae(Gshiyama 1923)Dye,1978〕Ⅰ—Ⅳ菌群的抵抗性,它们的抗感性按照品种×菌株的互作反应,可划分为6个类型,以中抗品种“华竹40”为亲本杂交育成的新品种均表现不同程度抗病。其中尤以“青华矮6号”的抗病性最好。“青华矮6号”是采用多系杂交育成的一个纯晚型中迟熟、丰产抗病、米质好的品种,测试证明对广东Ⅰ、Ⅱ、Ⅲ及Ⅳ菌群表现高抗,对优势菌群的抗病等级为1.3～1.4,CK_1(IR_(26)抗病)为0.84～1.2,CK_2(二白矮感病)为6.0,抗性差异达到显著水平,L.S.D=0.77(P=0.05),主要抗性基因为Xa_4。该品种经3年多点大面积验证试验结果,它的丰产抗病性表现一致。

| Abstract: | 6026 cultivars of barley of both domestic and foreign origin were tested for resistance to barley yellow mosaic virus (BYMV) through three consecutive years in the heavily infested fields of Zhou-Shan region,Zhejiang Province.Some of the more important cultivars have been subjected to more than ten trials at multipoint tests.This work resulted in selection of 36 cultivars showing complete freedom from yellow mosaic disease,and 24 cultivars highly resistant.These cultivars may be valuable as sources of resistance to barley yellow mosaic virus in barley breeding work. |
