陕甘小麦品种及抗源的高温抗条锈性研究

High-temperature resistance of wheat cultivars to wheat stripe rust

小麦苗期接种条锈菌(PucciniastriiformisWest.)后,分别采用高温(21±1)℃和常温(14±1)℃处理,测定了陕西、甘肃两省主栽品种及抗源的高温抗条锈性。结果表明,陕927、陕897、兰天1号、豫麦21和钱保德等品种具有高温抗条锈性,陕农757、西植9420、M8003-06、绵阳11、繁6、天选36和里勃留拉等品种可能具有高温抗条锈性。

The high temperature resistance of wheat cultivars from Shaanxi and Gansu provinces to wheat stripe rust is investigated in wheat seedlings inoculated with Puccinia striiformis West.by high temperature treatment (21±1)℃ and normal temperature treatment (14±1)℃,respectively.The result shows that wheat varieties,such as Shaan 927,Shaan 897,Lantian 1,Yumai 21 and Chambord,are of high temperature resistance to stripe rust;Shaannong 757,Xizhi 9420,M8003 06,Mianyang 11,Fan 6,Tianxuan 36 and Libellula are probably of high temperature resistance to stripe rust.
