Abstract: The starch of wheat is consist of two kinds of starch: amylase and amylopectin, in the synthesize of the amylase, there is an important synthase named waxy protein, which is coded by wx-a1,wx-b1 and wx-d1 located on chromosome of 7a,4a and 7d. When all of them are missed, the wheat becomes waxy wheat, and the content of amylase is none or very low, which has a great influence on the quality of the dough. As the big use of the waxy wheat, a research upsurge appeared, the waxy wheat was breeded. While deep we go in the research, now mutantions on the wx locations. On this paper, we reviewed the problems metioned above, also problems and prospect were analysed.
