| Abstract: | With Chinese representative inbred lines of Huangzao 4,Ye 478,Dan 340,Qi 319,Huang C,Mo17 as control, the ecological adaptability of 28 Brazilmaize materials in Pingliang city of Gansu province was analyzed. The results showed that 28 externalmaterials were able to mature normally in Pingliang city of Gansu province,which the yield of part of the material in ear length,ear diameter,rows per ear,kernels per row,1 000 grain weight were better than the domestic representative inbred lines,it can be used directly as a matching parents. |
