The improvement of wheat cultivar cannot be done without resistant germplasms. Distant hybridization has been a useful way in the creation of new. disease-resistant wheat germplasms. Using distant hybridization, the disease-resistant genes of the near genera of wheat can be transferred to the common wheat. However, the separation generation of distant hybrids is relatively long, and no effective approach has been developed to shorten this generation. It is very difficult to obtain stable wheat lines which have improved The improvement of wheat cultivar can not be done without resistant germplasms.
