Abstract

Abstract: One Wx 7D (null) variety “Baimangbai” and six Wx 4A (null) varieties were successfully selected by 1 D SDS PAGE from 900 landraces in Hebei. The frequency of normal type>Wx 4A (null) >Wx 7D (null) >Wx 7A (null) . Wx 7D (null) is a very important gene. It again shows that the materials in China are a special group. These materials discovered here made a solid foundation of the research on noodle quality breeding in China. This variety will be valuable in the theory study and application in wheat starch genetics and quality breeding. It also has a very good future in the development and utilization of amylopectin.

Key words: Wheat, Landraces, Wx genes, Constitution
