In order to meet the needs of the market, China Seed Group Co., Ltd. cooperated with Rice Research Institute of Anhui Academy of Agricultural Sciences to carry out the breeding of high quality, high yield, multi-resistance and two-line mid-season indica hybrid rice. Currently, rapid progress has been made to obtain a number of high yield, high quality rice, strong resistance, wide adaptability of materials and varieties, of which the Anhui Provincial Academy of Agricultural Sciences Institute of Rice breeding thermo-sensitive genic male sterile line New Second S, Xin Liangyou 998, which was crossed with the conventional mid-season indica rice variety h0998 bred by Rice Research Institute of Anhui Academy of Agricultural Sciences, showed high yield, good quality and multi-resistance with wide adaptability after many years of experiment. 1 Breeding After 1.1 Maternal New Second S The Rice Research Institute of Anhui Academy of Agricultural Sciences was bred with Xin’an S // Xin’an S / 2301S and arranged in Hainan in the spring of 2004. In the autumn of the year, Xinhui S was backcrossed and the BCF1 population was planted in winter 22 plants were planted in 2005 BCF2 from
