选用福建省农业科学院水稻研究所选育的12个杂交稻新品种,进行高留桩再生力筛选试验。通过对供试品种的产量、产量构成因素和生育期等主要农艺性状进行综合分析,筛选出福农优2358、聚两优676和谷优676等3个具有头季产量高、再生力也高的“双高”特性的杂交水稻品种。
12 new hybrid rice combinations developed by Rice Research Institute of Fujian Academy of Agricultural Sciences were selected and conducted for screening of ratooning ability with high stubble. By comprehensive analysis of main agronomic characters such as grain yield, yield components and growth duration from these tested combinations, three hybrid rice combinations Funongyou 2358, Juliangyou 676 and Guyou 676 were screened due to their good characteristics with high yield in the first crop and high ratooning ability.
