摘要
[目的]为高产粳稻新品种的推广提供参考。[方法]以豫粳6号为对照，对大穗型粳稻新品种新选1号、蒲粳2号、3优32、两优豫101、X65003、郑稻05094、郑选3号、新粳优1号、焦杂粳1号和金稻1008进行品种比较试验，分析各品种的产量及产量构成因素。[结果]供试品种中有8个品种较对照增产，增产幅度为1．4％～11．2％，其中较对照增产5％以上的品种有6个，分别为郑稻05094（增产11．2％）、焦杂粳1号（增产10．3％）、新粳优1号（增产9．9％）、X65003（增产8．8％）、两优豫101（增产8．7％）、新选1号（增产6．3％）；进一步分析发现，株高增高、长势增强、穗长增加、穗总粒数和实粒数大幅度增加是大穗型粳稻品种高产的主要因素。[结论]供试的部分品种可代替豫粳6号在黄淮稻区大面积推广种植．
[ Objective ] The study was to provide the reference for gonemtion of new japonica varieties with high yield. [ Method] With Yujing 6 as CK, new japonica varieties with large spike （Xinxuan 1, Puging 2, 3 You 32, 2 Youyu 101, X65003, Zhengdao 05094, Zhengxuan 3, Xinjingyou 1, Jiaozajing 1 and Jindao 1008） were taken for variety test, the yield and yield components of each variety was analyzed. [Result] Among the tested varieties, the yields of 8 varieties were higher than that of CK and their increasing in yield was 1.4 % -11.2 %. The yields of 6 varieties were above 5 % higher than that of CK, that were Zhengdao 05094 （increasing by 11.2%）, Jiaozajing 1 （increasing by 10.3%）, Xinjingyou 1 （increasing by 9.9 % ）, X65003 （ increasing by 8.8 % ）, Youyu 101 （ increasing by 8.7 % ）, Xixuan 1 （ increasing by 6.3 % ）. Further analysis indicated that the main reason of high yielding of japonica variety was the increasing of plant height, growth vigor, spike length, total grain number and filled grains number per spike. [Conclusion] Some tested varieties could be generated and planted in Huanghuai rice region in large scale replaced Yujing 6.
