Abstract: On the basis of the study results, unreduced gametes(2n gametes) which are less and very important forplant breeding can be found throughout plant evolution. The present paper reviewed the general researches, the classification,the formational mechanism and the influencing factors about 2n gametes, and these could give possible for our work on breeding, utilization and innovation. Concluding a lots of fruit researches, the main kinds of ways on breeding aboutinducing and artificial purity of 2n pollen were summarized. So different methods could be selected for various fruit po-llens. In addition, the 2n gametes hybrid off springs have many advantages such as the sexual polyploidization and thetransfering of heteroz ygosity stably, it aslo could avoid the phenomenons on sel-f incompat ibility and Endosperm balanc enumber (EBN) which other ways of breeding can bring. So, in the future, the breeding way through 2n gametes is we-lcome.

Key words: Unreduced gametes (2n gametes) , Classification, Formation mechanisms, Art ificial inducement , Purificat ion, Utilization
