Abstract: the genetic correclation and path analysis on agronomic traits and kernel yield of maize hybrids show that the factors namely the number of kernal per row, the number of row per ear ,100-grain weight and the ear length are dominant in affecting kernel yield .so,it is recommended to be better put emphsis on increasing the number of kernel per ear with the number of ear per plant unchanged to improve kernel yield per plant;upgrade the number of row to raise 100-grain weight;corrdinate the relationships among the number of row per ear;the number of kernel among the number of yow per ear and 100-grain weight to rationally achieve the improvement of kernel yield per plant greatly.
