| Abstract: | 5 maize inbred lines were crossed by Griffing Ⅳ design for new variety breeding and then the 10 crosses were evaluated.The combining ability of inbred lines for plant height,stem diameter,ear height,grain weight per plant,leaf area per plant,fresh ear weight per plant,fresh weight per plant and organism yield per plot were analyzed.The results showed that the difference of general combining ability（GCA）and special combining ability（SCA）for plant height,stem diameter,leaf area per plant,fresh ear weight per plant,fresh weight per plant and organism yield per plot were significant except the SCA of ear height and grain weight per plant.Fm24-1 and 77-1 were found to be elite maize inbred lines.And Fm 24-1/Qing 226-1 and H4171-2/77-1 were two good combinations. |
