| Abstract: |
| 【Objective】 The objective of this work was to identify the wheat cultivars containing the Lr37-Yr17-Sr38 using molecular makers,providing materials and theory for new cultivars breeding.【Method】 The Lr37-Yr17-Sr38 cluster was detected by PCR marker specific for the N genome,CAPS marker and pedigree and 126 wheat cultivars were analyzed.【Result】 Out of 126 cultivars，12 cultivars(Lankao 906，Zheng 2062，Xinong 739，Shan 872，Xiaoyan 216，Shan 538，Shan 515，Datang 991，0020-332，2871 and 378) were identified to contain the Lr37-Yr17-Sr38．【Conclusion】 To some extent,Yr17-Lr37-Sr38 cluster exists in Huanghuai wheat region.It’s presumed Lankao 906 is one of the most important mainly diffuse cultivars of Lr37-Yr17-Sr38 in China. |
