Wheat stamen pistillody refers to the phenomenon of homologous transformation of wheat stamens into pistils or pistil-like structures. The stamens can be normally seeded after complete pistillody, which increases the number of grains per spike and yield of wheat. Incomplete pistillody of stamens leads to male sterility. In this paper, the flower development process of wheat, wheat floral organ development model and homeotic mutantion, as well as the four kinds of wheat stamen pistillody materials obtained at present were briefly introduced, the regulatory mechanism leading to stamen pistillody of wheat and the effect of ethylene on stamen pistillody of wheat were analyzed, which provides a reference for the study of wheat flower development, and also provides a theoretical basis for genetic improvement and molecular design breeding of wheat.
