Abstract: To illustrate the discovery, identification of Taigu male sterile wheat were illustrated, and the gene was located in 4DS. It was found that it is a dominant gene and named Ms2. Looking for restorer line for Ms2 was made, but it is difficult. The dwarf gene of wheat was reported in 4DS of wheat, are the dwarf gene and Ms2 linkage? After test, the results indicated that they are closely linked, so, Liu (1986) created a dwarf male sterile wheat. It provided a platform for wheat breeding. According to the platform in recent decades, new varieties were bred. These varieties were grown in large scale (more than ten million hectare), but all the varieties are pure inbreed lines. Can the platform be used in hybrid breeding? The answer is definite. We should find a mark gene which would be closely linked to dwarf gene in the future study.

Key words: Taigu male sterile wheat, dwarf male sterile wheat, recurrent selection, heterosis
