摘要
用细胞核隐性雄性不育系 4 32 A与双低恢复系黔油 114 C测配 ,通过单株成对筛选测定出强优组合黔杂 93114 ,于 1999年通过贵州省农作物品种审定委员会审定 ,定名为黔油 11号。该组合在贵州省区域试验中最高产量达 3889.5 kg/ hm2 ,平均产量 2 4 35 .85 kg/ hm2 ,较对照品种秦油 2号增产 17.86 % ,且早熟5 d;在长江流域区试中最高产量达 32 10 .0 kg/ hm2 ,平均产量 2 172 .15 kg/ hm2 ,较对照中油 82 1增产 5 .2 6 % ,且早熟 2 d;表现出丰产、稳产、中早熟和适应性较强等优点 ,适宜于中高海拔地区及长江流域中下游双季稻作区种植。
The excellent combination Qianza 93114 was selected out by crossing GMS 432A with double low line Qianyou 114C. It passed examinations and approved by Guizhou Crops Variety Examination Committee and named Qianyou 11 in 1999. Its highest yield reached 3889.5 kg/ha when average yield was 2435.85 kg/ha in regional test of Guizhou, its yield increased by 17.86% and maturing time was 5d shorter than CK Qinyou 2. Its highest yield reached 3210.0 kg/ha when average yield was 2172.15kg/ha in regional test of Yangtse River, its yield increased by 5.26% and maturing time was 2d shorter than CK Zhongyou 821. Qianyou 11 displayed high yield, stability, medium or early maturing and good suitability. It is suitable to popularize in the area of medium or high altitude and double cropping of rice.
