Advantages and disadvantages of male sterility breeding methods

Using male sterile lines to prepare hybrids can save manual emasculation, reduce production costs and improve seed production quality. More importantly, it opens up a new way for the utilization of heterosis of some crops that are not easy to be emasculated manually, such as rice, sorghum and wheat. Using male sterility to prepare hybrid rice in China has not only significantly increased production in China, but also entered the international market, which has aroused strong repercussions and its development prospects are encouraging.
