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。

摘  要：
[Objective] The study was to provide the reference for generation 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.
