Research Progress on Plant 2n Gamete and Its Application
The 2n gametes play an important role in plant evolutionary process. At present, spontaneous and induced In gametes have been applied in crop breeding practice of potatoes, alfalfa, tradescantia virginiea,red clover, blueberries, chili, Lilium brownie, and separately obtained good effect. This paper present the induction of plant 2n gamete and its formation mechanism, breeding significance and application conditions in plant genetics and breeding at home and abroad, illustrating the problems of 2n gametes application and future development.
