摘要
通过杂交和复交途径,聚合多个材料的优异性状,育成了新的三系恢复系黔恢785。用黔恢785与不育系金23A配组育成了杂交水稻新组合金优785。经贵州省2008—2009年区试鉴定,金优785平均单产9.62 t/hm2,比对照(II优838)增产9.27%;生产试验鉴定平均单产8.85 t/hm2,比对照平均增产5.27%;在贵阳地区进行高产栽培试验,最高单产达13.74 t/hm2。金优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2010年7月通过贵州省农作物品种审定委员会审定。金优785是适合贵州省一季迟熟中籼稻区种植的理想组合。
Jinyou 785,a new three-line hybrid rice combination was developed from the cross between male sterile line Jin 23 A and restoring line Qianhui 785.Qianhui 785 was bred by the way of cross and multiple-cross with good characters.The results showed that the average yield of Jinyou 785 was 9.62 t/hm2,9.27% higher than that of CK in multiple-location regional experiment test during 2008-2009,and the average yield was 8.85 t/hm2,5.27% higher than that of CK in one-year productive experiment test in Guizhou province,and the highest yield was up to 13.74 t/hm2 in high-yielding cultural experiment in Guiyang region.The resistance to rice blast,rice physicochemical indexes and tastes of Jinyou 785 were all better than CK.The new combination is suitable for the region of single cropping of rice in Guizhou province.It was registered as a commercial variety in 2010 in Guizhou province.
