[Objective] The research aimed to understand the high and efficiency technique in intersubspecific hybrid rice Yongyou No.9. [Method] We conducted the correlation analysis, regression analysis and path analysis of intersubspecific hybrid rice Yongyou No.9 based on the data of its ear, grain and weight at different yield levels. [Result] It was showed that the direct contributions of main economic traits to yield were determined to be per ear total grains effective ear seed setting rate 1000-grain weight. The high-yield and effective cultivation techniques were suggested as follows: on the basis of certain effective ear number, grain number per ear should be mainly focused with a consideration to 1000-grain weight.
