Objective The paper was focused on the way how to increase the yield of hybrid rice Zhongzheyou No.8. [Method] The relationship among yield-related traits and their contribution to yield were investigated through correlation analysis, regression analysis and path analysis. [Result] The performance of ear, grain and weight in Zhongzheyou No.8 showed significant difference among yield levels. The enhancement of effective ears would restrain the number of total grains per ear. It was found that the direct contributions of main economic traits to yield were: num-ber of fil ed grains per ear > number of effective ears > 1 000-grain weight > num-ber of total grains per ear. [Conclusion] The promotion of high-yielding techniques was suggested as fol ows: on the basis of certain number of effective ears, number of fil ed grains per ear should be mainly focused with a consideration to grain weight.
