通过１９９７年全国区试资料，对Ⅰ优４７６１的产量、生育期、稻瘟病抗性及稻米品质４个性状进行了分析。结果Ⅰ优４７６１在一季中稻的３９个试点中，平均产量为８６０５５ｋｇ／ｈｍ２，比对照组合汕优６３增产０４％；在福建沙县良种场的晚稻区试点中，产量为８１００ｋｇ／ｈｍ２，名列参试组合之首，比对照组合汕优４６增产１４９％。按参试点计有５７５％的试点（２３个）比对照组合增产。按省级地域计有６６％的省（８个）比对照组合增产。Ⅰ优４７６１全生育期比对照汕优６３长０９ｄ。对稻瘟病的抗性明显优于对照组合，也是参试组合中对叶瘟和穗颈瘟抗性相对较好的组合之一。稻米品质指标与对照组合相当，获总评分５０分，略低于对照组合汕优６３（５２分）。其测试分析的９项理化指标中有７项达部颁二级米标准。表明Ⅰ优４７６１具有良好的应用前景，应加速推广和进行适度规模的开发。
Through the 1997 national district test data, the yield, growth period, blast resistance and rice quality of Ⅰ You 4761 were analyzed. Results The results showed that the average yield of Ⅰ You 4761 was 86055 kg / hm2 in 39 plots of middle season rice, which was 0.4% higher than that of Shanyou 63. In the trial of late rice in Shaxian County, Fujian Province, the yield was 8100 kg / hm2 , Ranked first in the test portfolio, compared with the control group Shanyou 46 yield 14 9%. According to the experimental sites, 575% of the pilot projects (23 units) increased compared with the control. According to the provincial level, 66% of the provinces (8) increased their production compared with the control. Ⅰ excellent 4761 whole growth period compared with the control Shanyou 63 long 0 9d. The resistance to blast was significantly better than that of the control, and it was also one of the better combinations of resistance to leaf blast and panicle blast in the combination. The rice quality index was comparable with the control group, with a total score of 50 points, slightly lower than the control group Shanyou 63 (52 points). Among the nine physical and chemical indicators tested and analyzed, seven reached the ministerial level two rice standard. It shows that Ⅰ You 4761 has a good prospect of application, should be accelerated to promote and conduct a moderate scale of development.
