On the basis of rice haploid breeding work in many years,the related techniques are improved to simplify culture protocol on the principle of cost-saving,to establish new haploid breeding system on the principle of high speed,and to broaden green plantlet population and re-use pollen plants on the principle of enriching genetic background.

The haploid breeding of maize is a technology that using anther culture or gynogenesis to produce haploid,and then obtain stable new varieties through natural or artificial doubling.

The current advance in the haploid breeding reviewed in recently teen year,and the path that using hap- loid technology was applied to breeding and molecular biology of medicinal plant was showed,which offered the reference for the haploid breeding and basi.
