为了解闽恢3301系列杂交稻新品种的产量性状，选用恢复系闽恢3301配组育成的5个杂交稻品种为研究材料，以Ⅱ优明86作对照，分析闽恢3301系列杂交稻新品种的产量与各构成因素间的相关及各构成因素对产量的贡献。结果表明，5个供试杂交稻品种的平均产量达11t/hm2左右，均比对照增产，除谷优3301外，差异达显著水平；产量与每穗粒数呈极显著正相关；通径分析结果显示，每穗粒数对产量的贡献率最大，达到55.58%。因此，栽培过程中，在保持一定穗数的基础上，应注意培育大穗，发挥超高产杂交稻的产量潜力。
為瞭解閩恢3301繫列雜交稻新品種的產量性狀，選用恢複繫閩恢3301配組育成的5箇雜交稻品種為研究材料，以Ⅱ優明86作對照，分析閩恢3301繫列雜交稻新品種的產量與各構成因素間的相關及各構成因素對產量的貢獻。結果錶明，5箇供試雜交稻品種的平均產量達11t/hm2左右，均比對照增產，除穀優3301外，差異達顯著水平；產量與每穗粒數呈極顯著正相關；通徑分析結果顯示，每穗粒數對產量的貢獻率最大，達到55.58%。因此，栽培過程中，在保持一定穗數的基礎上，應註意培育大穗，髮揮超高產雜交稻的產量潛力。

To understand the yield traits of high-yield hybrid rice varieties, 5 super high yield varieties from Fujian province and control variety Ⅱ You ming 86 were used to analyze the correlation between yield and its components. The contribution of yield components to yield also investigated. Results showed the average yield of 5 varieties were about 11 t/hm2. In addition to Guyou3301, the rest of the four varieties all showed highly significant difference from control variety. There was positive highly significant between yield and grain number per plant. Path analysis showed grain number contribute most to yield, its coefficient was 0.55. As a result, in rice culturing practice, based on enough panicles, developing heavy panicles should play a role on yield potentiality.
