摘要
Abstract
Experimental was conducted with material of 9 inbred lines,18 hybrid combinations were set according to incomplete diallel cross method (NC Ⅱ).The maize ear data of 9 parents and 18 F1 generations were used to analysis the main genetic quantitative traits,including heritability,combining ability and relative effect.The results showed:ear,ear diameter,ear row number should be selected in the early generation;bald,spike number,double spike rate should be selected in later generation;combining ability effect in different materials.Selfing line 2021,2402 and 2508 could be used as excellent parent breeding material to improve double spike rate.2508 and B73 showed certain application value in dwarf ear place breeding.关键词
