| Abstract: | In order to explicit the genome structure in Northeast China japonica,the changes in genetic diversity and genome structure during breeding were studied on the 79 northeast China Japonica in different periods using 52 genome-wide SSR loci.The results showed that genetic diversity of japonica cultivars from large to small sequenced for Liaoning,Heilongjiang,Jilin and 2001~2008,1981~1990,1991~2000,1963~1980.The proportion of indica ingredient from small to large was Liaoning,Heilongjiang,Jilin and varieties i... |
