Title: Heredity Analysis on Combining Ability of Seven Corn Inbred Lines Main Ear Characters
Abstract: According to the Griffing’s mode fourth,7 inbred lines 4 panicle characters combining ability and heritability were tested.The results showed that:(1) the GCA of D 902,Su 65 and 1043 on grain weight per spike were higher,Dandacuhun had increased in ear diameter,GCA of ear rows was higher.(2) Su 65 × 1043,Dandacuhun × 96-132,Dandacuhun × D 902,1441 × 1043,1043 × 51 were superiority combination among 21 combinations,and the combination of single grain weight of SCA was higher.(3) the character of ear length,ear diameter,rows per ear and grain weight were influenced by the additive gene effect,early generation selection was the best method to take;plant height,grain number per row,ear height,ear,grain weight per panicle affected by non-additive effect,should be selected later.
