为选育新的杂交水稻新品种应用于贵州水稻生产，采用杂交和复交途径，聚合多个材料的优异性状，育成新的三系恢复系 G569，再用 G569与不育系川香29A 配组育成杂交水稻新组合川香优569，经贵州省2010-2011年区域试验，川香优569平均单产9．22 t/hm2，比对照（Ⅱ优838）增产7．29％；2012年生产试验平均单产为8．38 t/hm2，比对照平均增产6．70％。川香优569的稻瘟病抗性、稻米理化指标和食味鉴评结果均优于对照，于2014年6月通过贵州省农作物品种审定委员会审定，适合贵州一季中籼迟熟稻区种植。

To breed new hybrid rice combinations and apply in Guizhou rice production, Chuanxiangyou569,a new three-line hybrid rice combination was developed from the cross between male sterile line Chuanxiang 29A and restoring line G569 bred by the way of cross and multiple-cross with good characters.The average yield of Chuanxiangyou 569 was 9.22 t/hm2 ,7.29% higher than that of CK in multiple-location regional experiment during 2010-2011;and the average yield was 8.38 t/hm2 ,6.70%higher than that of CK productive experiment in Guizhou province in 2012.Rice resistance to rice blast, rice physico-chemcal indexes and tastes of Chuanxiangyou 569 were better than CK,and Chuanxiangyou 569 was registered as a commercial variety in Guizhou province in June 2014.The new combination is suitable for the region of single cropping of rice in Guizhou.
