Analysis of Genetic Difference Between Species in Lupins by AFLP

The genetic difference between species in 18 lupins (Lupinus L. ) varieties including L. angustifolius L., L. albus L., L. pilosus Murr. was analyzed using AFLP. A total of 462 bands were observed, among of which, 442 (95.7%) were polymorphic, with an average of 110.5 polymorphic bands for each AFLP primer combination. The average genetic diversity index was 0. 781 in this study. The genetic difference between species was higher than that of between varieties, the average identification percentage of four AFLP primer combinations was 100% and 84.7% between species and between varieties, respectively. The cluster analysis indicated that 3 species were distinctly distinguished on the dendrogram using UPGMA method.
