Correlation,Regression and Path Analysis between Yield Traits and Yield of Yongyou No.9

[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]The performance of ear,grain and weight in Yongyou No.9 showed significant difference among different yield levels.The enhancement of effective ears would restrain the number of per ear total grains.It was found that the direct contributions of main economic traits to yield were determined to be per ear total grainseffective earseed setting rate1 000-grain weight.[Conclusion]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 1 000-grain weight.
