Wandao79, which is the two-line medium indica hybrid derived from X07S/zihui100, was developed by Rice Research Institute, Anhui Academy of Agricultural Sciences. It exhibited characteristics of high and stable yield. In medium-indica-group regional test during 1998-1999 and medium-indica-group productivity test in 2000 in Anhui, the average yield of Wandao79 was 8.45 t/hm 2, 7.83 t/ hm 2 , respectively. At Baihu farm in 1999, 9.16 t/hm 2 gained from 120 hm 2 increased by 19.44% than that of Shanyou63.It was registered and released in Anhui Province in 2000.
