The main advantages of haploid breeding are

Haploid plants were obtained by anther culture in vitro, and then the chromosome number was doubled by artificial induction, and then the chromosome number of normal plants was restored. The plants obtained by this method can not only reproduce normally, but also the paired genes on each pair of chromosomes are homozygous, and there will be no character separation in self-bred offspring. Therefore, it only takes two years to cultivate new varieties with haploid plants, and stable pure varieties can be obtained. Compared with conventional cross breeding methods, the breeding cycle is obviously shortened.
