用恢复系测64-7、美国香稻Jasmine-85、贵州地方粳稻选系和明恢86杂交育成香稻恢复系黔香恢875,再与香稻两系不育系360S配组育成杂交香稻新组合香两优875。该组合在贵州省杂交稻区试和生产试验中表现良好,每公顷产量分别为8.65和8.35t与对照相当;稻米品质达到国家优质稻谷3级标准,在2007和2008年贵州省杂交稻食味品质鉴定中均获第1名,2008年通过贵州省品种审定。该组合制种技术简便,在父母本花期相遇较好时每公顷制种产量可达3.75t左右。在香米生产中应用,有较高的经济价值。
Using restorer line 64-7, American fragrant rice Jasmine-85, Guizhou local rice selection line and Minghui86 hybridization restorer line Aixianghui 875, and then with the two lines of male sterile line 360S with aromatic hybrid rice New combination of rice Honglou 875. The combination performed well in the trial and production of hybrid rice in Guizhou Province with yield of 8.65 and 8.35t per hectare, respectively. The yield of rice reached the level 3 of national high quality rice. In 2007 and 2008, Identification of the first were the first, in 2008 through the Guizhou province species validation. The combined seed production technology is simple and convenient, and the yield per hectare can be up to about 3.75t when the parents meet with this flowering season. In the production of rice, there is a high economic value.
