Abstract

The genetic diversity among 20 wheat lines,which had been taken part in Guizhou province field trial in 2007-2009,was investigated by using SSR markers.The results showed that a total of 46 allelic loci were detected by a set of 12 primers.The number of alleles per primer pair ranged from 2 to 7,with average 3.83.Cluster analysis showed the average GD of the wheat varieties breeding was 0.321,ranging from 0.116 to 0.526.The GD among 20 wheat lines was calculated to 5 types based on SSR markers.The results indicated that it was an effective method of specific detection and variety protection using different wheat new variety of genetic diversity with core-primers.
