1997年度江苏省杂交中粳稻区试结果表明：（1）参试的杂交中粳稻，其杂种优势主要体现在穗、粒等穗型指标上，而穗数等群体指标和结实率明显低于武育粳3号；（2）各产量因素对环境变化的反应不一，其平均变异系数大小顺序为；穗数＞每穗实粒数＞结实率＞每穗总粒数＞千粒重；（3）综合丰产性和稳产性分析，泗优418不仅产量高，而且稳产性好。
The results of regional trials of japonica hybrid rice in Jiangsu Province in 1997 showed that: (1) Hybrid japonica hybrids tested mainly showed panicle and panicle panicle index, but the population index and seed setting rate were significantly lower than that of Yujing 3; (2) The response of different yield factors to environmental change varied with the order of average variation coefficient; the number of panicles> the number of filled grains per panicle> the rate of seed setting> the number of total grains per panicle> 1000-grain weight; Comprehensive yield and stability of the analysis, Si You 418 not only high yield, and good stability and good.
