| 摘要: |
| 用小麦条锈菌集中29号的7个突变菌株测定了我国42个重要抗源品种和52个衍生品种及47个区(预)试品种。结果表明,8个抗源品种对野生菌系和突变菌株仍保持免疫到中抗反应,以长穗偃麦草和6828-0-6-1-1为抗源的品种抗锈稳定性较好,4个区试和3个预试品种抗锈稳定性也较好。并对这些抗源的利用和后备品种的推广应用前景提出了建议。 |

| Abstract: |
| The resistant stalility of 42 major accessions for sources of rust-resistance,52 derivative cultivars of certain resistance sources and 47 regionaI test cultivarsand pre-regional test cultivars in Northwest China was tested by inoculating 7 mutantsfrom wheat stripe rust.The results showed that 8 accessions were resistance to all mutants and Cy29-1,which should be valuable in current whaeat breeding ,and derivativecultivars from Agropyron elongatum and 6828-0-6-1-1 were highly resistant to all mutants,Also,4 regional test cultivars and 3 pre-regional test cultivars have resistant stability. Some suggesions for cultivars release and application were recomanded. |
