张镝 %A 丁毅 %J 遗传 %D 2007 %I %X Seven primer combinations were used for AFLP analysis. The fingerprints of 36 wild close relatives of bar-ley in Tibet of China and 4 cultivated varieties of barley had been obtained,bringing about 227 discernable bands. Among the bands 194 were polymorphic with the percentage of 85.46%,indicating that the materials in the test have abundant ge-netic diversity. The genetic distance(Euclidean Distance) of samples computed by SPSS is between 2.646 and 10.488. Ap-plying Ward's method to cluster the AFLP data results,an AFLP dendrogram of 40 barley materials was then established. All samples were clustered into 5 groups,further revealing the similarity,complicacy of the genetic background and the relationship of phylogenesis of the barley materials tested. Consulting the genetic identity it was shown that six-rowed wild close barley is closer to cultivated barley than two-rowed wild close barley. This result supported the viewpoint that the six-rowed wild close barley was the intermediate type in the evolutionary route from the tow-rowed wild close barley to the cultivated barley. %K AFLP
