Abstract: Huihan S is a thermo-sensitive genetic male sterile rice line with fine drought-tolerance, bred by Rice Research Institute, Anhui Academy of Agricultural Sciences through hybridization of Lv 102S, female parent and drought-tolerance restoring line Lvhan 1, passed technical appraisal of Anhui Province in August 2016. Huihan S has the characteristics of good sterility, higher ratio of stigma exsertion and outcrossing rate, fine resistance and quality, and strong heterosis. The characteristics and propagation techniques were introduced in this paper.
