Abstract
Becausing of deficient of genetic background,It brings the great effects to breeding in maize.Introgression and application of exotic germplasm is a key way to solve the straitness of genetic background in corn breeding in China.and the study of heterotic group and pattern of maize is importand about enhancing breeding efficiency.the paper expounds the evaluation、the way of germplasm enhancement and creating new germplasm,and the change of heterotic group and pattern of maize.
