摘　　要：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。Xiangliangyou 875,i.e.,360S/Qianxianghui 875,is a new aromatic hybrid rice combination.The female parent 360S is an aromatic PTGMS line and the male parent Qianxianghui 875 is also an aromatic restorer line which is derived from multiple crosses of Ce 64-7（an indica restorer line）,Jasmine-85（an aromatic American rice）,Minghui 86（an indica restorer line）and a Guizhou native japonica variety.The hybrid combination had a good performance in the regional trials and production trials of Guizhou Provice during 2004 and 2006.It yielded 8 647.5 kg/hm2 in the regional trials and 8 346.2 kg/hm2 in the production trials on average,similar to the check hybrids Jinyou 77 and Jinyou 207.It has a high grain quality meeting to the 3rd class of national standards for fine quality rice.In the Hybrid Rice Taste Identification Meetings of Guizhou Province in 2007 and 2008,it was ranked No.1 in both years.In 2008,it was certified and released to commercial production in Guizhou Province.It could achieve a yield of 3 750 kg/hm2 under the condition of a good synchronization of flowering between both parents in its hybrid seed production.It would also have a high economic value in the application of aromatic rice production.
