Abstract:

Sorghum A3 cytoplasmic male sterility (CMS) anther was hypertrophy and yellow. It strewed some infertile pollens, so it had no fruit by self-pollination, and it had stable sterility. Most sorghum varieties can not maintain A3 CMS, but many high yield and stable sterility varieties can be transformed to A3 CMS. It restricted A3 CMS study that A3 CMS restorer lines were little, and restoration rate was 40%-95%. In order to utilize A3 CMS, restorer lines breeding must be solved. Breeding and application of A3 CMS line, restorer line and hybrid, and A3 CMS genetic expression were reviewed in the paper.
