Analysis of combining ability of major quantitative characters in sweet maize inbred lines

It is important to breed new lines and breeding work to analysis of combining ability.Twenty-eight crossing combinations were made according to incomplete dialed cross using 8 inbred lines of maize.Combining ability of major quantitative characters(plant height,ear height,plant diameter,ear length,ear diameter,row number per ear,kernel number per row,single ear weight and 100kernel weight) were analyzed by Griffing′s method.The results showed that Lu 9_(kuan)/sh_2 and 150/sh_2 have higher general and special combining ability.High yield combinations were easy obtained by using the above mentioned inbred lines as the parent.
