| 摘 要： | 2014年-2017年度先后对331份四川省小麦生产品种(系)在温室进行苗期人工接种条锈菌混合菌鉴定和甘谷试验站大田成株期分别接种CYR32、CYR33、CYR34、G22-14、中4-1和混合菌鉴定,同时在甘谷试验站和汪川良种场两地进行自然诱发鉴定。结果发现:在人工接种条件下,苗期、成株期表现抗病的分别有‘XK201465’等36份和‘XK20132’等72份材料,分别占10.88%和21.75%;有‘XK62483’等11份材料全生育期表现抗病,占3.32%;两地三年自然诱发鉴定发现,仅有‘XK20132’等5份材料在两地均表现抗病,有‘川农17’等30份材料具有慢条锈性。对供鉴材料在甘肃陇南的利用前景进行了分析。

| Abstract: | The resistance of 331 wheat cultivars (lines) from Sichuan Province to stripe rust was evaluated by manual inoculation of mixed isolates of Pst in seedling stage at Lanzhou Greenhouse, single race/isolate of CYR32, CYR33, CYR34, G22-14, Zhong 4-1 and mixed isolates of Pst in adult stage at Gangu station, IPP GAAS during 2014-2017. The resistance to natural Pst was also identified at Gangu station, IPP GAAS and Wangchuan farm. The results showed that 36 wheat varieties were resistance to mixed isolates of Pst in seedling stage, accounting for 10.88%. 72 wheat cultivars (lines) were resistant to tested single and mixed races/isolates of Pst in adult stage, accounting for 21.75%. 11 wheat cultivars (lines) were resistant in all-stage, accounting for 3.32%. Only 5 wheat cultivars (lines) were resistant to natural Pst in field at Gangu station and Wangchuan farm. 30 wheat cultivars (lines) had slow rusting characters. Their utilization prospect in southern Gansu Province in future was also analyzed in this paper. |
