三系杂交水稻新组合湘菲优785的选育

Breeding of Three-line Hybrid Rice Xiangfeiyou 785

利用自育三系恢复系黔恢785与从湖南省科裕隆公司引进的不育系湘菲A配组,育成了杂交水稻新组合湘菲优785。经贵州省2009—2010两年杂交水稻区试鉴定,湘菲优785平均单产8.85t/hm2,比对照II优838增产5.23%;经2011年生产试验鉴定,平均单产9.87t/hm2,比对照平均增产6.52%。湘菲优785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2012年6月通过贵州省农作物品种审定委员会审定(审定证书号:黔审稻2012001号)。湘菲优785是适合贵州省一季迟熟中籼稻区种植的杂交水稻新组合。

Xiangfeiyou 785 was a new three-line hybrid rice combination developed from the cross between male sterile line Xiangfei A（introduced from Keyulong company in Hunan） and male restorer line Qianhui 785（bred by Guizhou Rice Institute）. The average yield of Xiangfeiyou 785 was 8.85 t/ha, 5.23% higher than that of CK in multiple-location regional experiment test for two years（2009--2010）. The average yield was 9.87 t/ha,6.52% higher than that of CK for one-year productive experiment test in 2011 in Guizhou Province. The new combination is suitable for the region of single cropping of rice in Guizhou Province and has good prospect of utilization. It was registered as commercial variety in 2012 in Guizhou Province（accreditation certificate No. Qianshendao 2012001）.
