介绍了杂交稻新品种谷优2736在诏安县示范种植的产量表现，对其产量与4个构成性状进行了相关和通径分析。结果表明，谷优2736在诏安县示范种植的产量水平达8143.4kg/hm2；产量与每穗粒数、千粒重呈极显著的正相关，与有效穗数、结实率相关不显著；每穗粒数对产量形成起正向直接作用最大，千粒重次之，有效穗数较小，而结实率对产量起较小的负向直接作用；高产栽培技术上，应在兼顾有效穗数和结实率的基础上，主攻每穗粒数，提高粒重，充分发挥该品种的增产潜力。
介紹瞭雜交稻新品種穀優2736在詔安縣示範種植的產量錶現，對其產量與4箇構成性狀進行瞭相關和通徑分析。結果錶明，穀優2736在詔安縣示範種植的產量水平達8143.4kg/hm2；產量與每穗粒數、韆粒重呈極顯著的正相關，與有效穗數、結實率相關不顯著；每穗粒數對產量形成起正嚮直接作用最大，韆粒重次之，有效穗數較小，而結實率對產量起較小的負嚮直接作用；高產栽培技術上，應在兼顧有效穗數和結實率的基礎上，主攻每穗粒數，提高粒重，充分髮揮該品種的增產潛力。

This paper introduced the yield performance of new hybrid rice variety Guyou 2736 demonstration planting at Zhao,an County, and the correlation and path relationship of yield and its four component traits were analyzed.The results showed that Guyou 2736 hybrid rice yield an average of 8143.4 kg/hm2 at Zhao,an county. The yield was very significantly positively correlated with total grain number per plant and 1000-grain-weight, and not significantly correlated with effective panicles per plant (PP) and seed-set percent. Yield was positively directly affected by total grain number per plant , 1000-grain-weight and effective panicles per plant, and was negatively directly affected by seed-set percent. Cultivation strategy for high yield should be taken into account the basis of effective panicles and seed-set percent, increase total grain number per plant and 1000-grain-weight , in order to give full play to the variety yield potential.
