| Abstract: | The paper separately forecasted the winter wheat heterosis by means of ge-netic distance and canonical genetic distance to compare the forecasting efffect of two dis-tances. The result showes that forecasting heterosis by genetic distance is simple and convenient. And the heterosis selected hybrid combinations according to the genetic distance con-form with the actual situation. So the genetic distance is a better index than another one. |
