Among the many sweet waxy corn seeds, there are ten excellent varieties such as Wannuo 20000, Nongkenuo 336, Ruitiannuo 2 15 and Huafengnuo. These waxy corn, also known as sticky corn or waxy corn, are highly favored by corn industry because of their unique cultivation advantages and multifunctional uses. Their origins can be traced back to the southwest of China. Hard corn gradually developed waxy characteristics through natural mutation and artificial breeding, which embodies the genetic inheritance of "China species".

Waxy corn kernels are characterized by their rich waxy endosperm, which is more shiny than the transparent kernels of hard corn and horsetooth corn. Its unique chemical and physical properties are mainly controlled by the recessive gene wx located on chromosome 9, which makes its 100% starch Amylopectin. The waxy nature makes them attractive in diet, which can not only be directly used as fresh food for people to enjoy, but also be used as livestock feed to improve the digestion efficiency of feed. In addition, waxy corn has also been applied in the industrial field, showing its extensive use value.
