| 摘 要： | 研究用ＲＦＬＰ方法，对我国主要小麦产区，陕西省４０年代以来广为种植的小麦品种的遗传多样性进行了研究，结果表明，占总带数２６．２％的ＨＩＮＤＩＩＩ酶的ＲＦＬＰ带具有遗传多态性。２４个小麦品种平均遗传相似系数为０．９４８。５３．８％的探针显示了多态性。平均多态性信息含量指数为０．２５２。陕西省小麦品种遗传多样性以７０年代为最高，之后开始降低。 |

| Abstract: | Genetic diversity in a set of 24 wheat lines which was widely planted from 1940s to 1990s,in Shaanxi Province,one of the main wheat production areas,was measured by using RFLP assay.On average,26.2% of all bands revealed by HindIII enzymes with 26 RFLP clones were polymorphic.The average pairwise genetic similarity (GS) was 0.948.Probe polymorphism information content index (PIC) was 0.252.53.8% of the 26 probes revealed any polymorphism.The genetic diversity of wheat lines in Shaanxi Province decreased from 1970s. |
