摘要
为促进水稻新品种的育成,实现贵州水稻生产上新老品种的更替,贵州省水稻研究所用自育恢复系黔恢93与福建省农业科学院水稻所选育的不育系民源A组配育成杂交水稻新组合民优93。经贵州省2012—2013年杂交水稻区域试验鉴定,该组合平均单产9.43t/hm^2,比对照香早优2017增产9.85%,2年共16个点(次)中15增1减,增产点率94%;经2013年生产试验鉴定,平均单产9.09t/hm^2,比对照平均增产5.96%;其稻瘟病抗性、耐寒性均明显优于对照香早优2017。民优93于2014年6月通过贵州省农作物品种审定委员会审定(黔审稻2014010号),适宜贵州省中高海拔籼稻区种植。
Minyou 93, a new hybrid rice combination, was bred from Minyuan A （a sterile line bred by Rice Institute, Fujian Academy of Agricultural Sciences）Qianhui 93 （a restorer line bred by Guizhou Rice Institute） to promote breeding of new rice varieties for realizing the replacement of the old and new varieties in rice production in Guizhou. The average yield of Minyou 93 in Guizhou hybrid rice regional tests in 2012 and 2013 is 9.43 t/hm2 , 9.85%higher than CK （Xiangzaoyou 2017） and the rate of test sites with yield increase is up to 94%. The yield of Minyou 93 in Guizhou rice production test in 2013 is 9.09 t/ hm2 , 5. 96% higher than CK. The resistance to rice blast and cold tolerance of Minyou 93 both are better than Xiangzaoyou 2017 obviously. Minyou 93 approved by Guizhou Crops Variety Examination Committee can be cultivated in Indica rice producing area with middle-high elevation in Guizhou.
