摘　　要：抗条锈病小麦新种质９２Ｒ１４９ 系南京农业大学细胞遗传研究所利用簇毛麦创造的普通小麦６ＶＳ／６ＡＬ易位系。经绵阳市农科所５ 年的观察和利用研究，发现它具有对条锈病和白粉病高抗～免疫、抗性遗传力强、配合力好、综合农艺性状较好等突出特点，是四川省小麦抗病育种可资利用的难得的优良抗条锈病和白粉病新抗源。但其植株偏高，分蘖力强，有效穗数偏少，籽粒偏小且为红粒，在利用中应注意予以改善。The new stripe rust resistant wheat germplasm 92R149, Triticum astivum Haynaldia villosa translocation line (6VS/6AL), was created by the Cytogenetics Institute of Nanjing Agricultural University. It has the characteristics of immunity or high resistance to stripe rust and powdery mildew, strong heritabilty of the disease risistance, good combining ability, excellent comprehensive agronomic traits. 92R149 will be a new excellent source of resistance to stripe rust and powdery mildew for wheat breeding in Sichuan province.
