Analysis on Correlation between Rice Panicle Traits and Yield

WANG Chang-hua1,2,XU Zheng-jin1,XIA Yong-sheng3 et al.(1.Shenyang Agricultural Lniversity,Liaoning,Shenyang 110161;2.Liaoning Academy of Agricultural Sciences,Shenyang 110161;3.Shenyang Agricultural Brodcast School 110034)  
This study analyzes the relation between rice panicle traits and between yield and them,by using varieties bred lately in Liaoning Province.The results are as follows: Grain number per panicle,seed density,secondary branch number,secondary branch grain number,secondary branch grain rate are significantly positively correlated with rice yield, the yield is affected by all of them.The panicle seed setting rate is mainly confined by secondary branch seed setting rate,and they have significantly positive correlation.Primary branch number,secondary branch number,primary branch grain number,secondary branch grain number and secondary branch grain rate are significantly positively correlated with grain number per panicle.There is a significantly linear relation between secondary branch grain number and grain number per panicle,and they have the same changing tendency.In addition,increasing of 1 000-grain weight is important in rice's potential yield.
