Analysis of Combining Ability and Application Potential of the Elite Maize Inbred Line L102

There are 28 crossing combinations were made on L102 and other seven inbred lines of maize by Griffing II design in this experiment.The GCA,SCA and CA of plant height,ear height,fruit length,ear width,kernel per plant,grain number per row,100 kernel weight and grain yield thought were analyzed by LNT software.The result showed that the GCA,SCA of L102 with the traits of length ear,high kernel per plant and low plant height were higher.It can cross combination with the traits of length ear and big grain to select the good crosses.L102 inbred line with China 4 heterotic group and P group have the higher SCA,especially,L102×Lvdahonggu group and L102×improvement huangzaosi are the best heterotic pattern.
