Abstract: The standard operation procedure of producing parental seeds was established with the purpose of providing high quality parental seeds for producing the two-line hybrid rice Liangyou 289. A total area of 15.3 hm2 was used to produce the CMS line 1892S in 2013. On average, there produced 2.265 million panicles per hm2, with 165.5 total grains per panicle, the seed setting rate is 83.9%, the 1000-grain weight is 23.0 g, the yield is 5788.5 kg/hm2 and the purity of the produced seeds is over 99.98%.

Key words: two-line hybrid rice, Liangyou 289, parent, seed production
