玉米株高、穗长与产量分别是极显著和显著正相关，在组配杂交组合时，两者应列为重点考虑性状。7912、HZ47和ES40具有较高的产量配合力效应，用它们测配，易筛选出高产组合。7912、HZ47、330、材11－8、200B、ES40和537株高配合力效应值较大．其组合后代比较高大。莫材－1、7912、材11－8、ES40和0151－2易抬高穗位，而5003、30－221、32和3H－2却有降低茎秆和穗位的作用、莫材-1、7912、村11－8、ES40、537和双自212－3的穗长配合力效应值高，易选配出长穗型组合。用莫材-1、48－2、牛2－1、材11－8、200B、ES40和3H－2组配，可获得大粒型组合。
Plant height, spike length and yield of maize were extremely significant and significant positive correlations, respectively. 7912, HZ47 and ES40 have higher yield combining ability, and they can be used to test the yield and easy to screen the high yield combination. 7912, HZ47, 330, material 11-8, 200B, ES40 and 537 were higher with higher combining ability. Its combination of offspring is tall. Mo-1, 7912, Ti-11-8, ES40 and 0151-2 could easily raise ear position, while 5003, 30-221, 32 and 3H-2 had the effect of reducing stalk and ear position. , 7912, 11-8, ES40, 537, and Shuangzeng 212-3 had high spike combining ability and easy combination with long spike. With the Mo-1, 48-2, Niu 2-1, materials 11-8,200B, ES40 and 3H-2 group configuration, can get large grain type combination.
