Abstract:

The key link of breeding and coalition of the new hybrid combination are realize the connection of genetic background of core germplasm between the new breeding inbred lines and the known. and identified heterotic groups which they belong, this study analyzed 46 the genetic diversity of maize inbred lines using the SSR markers, the results showed that: 12 pairs of stable SSR primers detected 45 alleles, the polymorphism information content of each SSR (PIC) ranged from 0.31 to 0.76 with an average of 0.57, the high polymorphism was been indicated. By clustering analysis, five groups were divided the 46 inbred lines, the result were as much as the pedigree, but a little difference. The result of this research had some function to the practice in breeding.
