title: Genetic diversity analysis of  barley landraces and cultivars in the Shanghai region of China.
abstract: We  analyzed the genetic diversity of 115 barley germplasms, including 112  landraces and three new barley cultivars grown in the Shanghai region, using a  set of 11 SSR markers. Sixty-six alleles were observed at the 11 SSR loci,  ranged from three to ten, with a mean of six alleles per locus. The  polymorphism information content ranged from 0.568 to 0.853, with a mean of  0.732, indicating considerable genetic variation in barley in the Shanghai  area. Clustering analysis indicated that these barley accessions could be  divided into two categories (A and B). Ninety-seven six-rowed barley cultivars  were classified in the A category; sixteen two-rowed and two six-rowed barley  cultivars were classified in the B category. This demonstrated genetic  differences between two-rowed and six-rowed barley varieties. In addition, we  found that the three new barley cultivars are closely related.
