Abstract: This paper established QZ58 and Q478 and QC72 isogenic lines; which were from normal corn lines Zheng 58 and 478 and Chang 72.And analyzed the hardness of different endosperm types among QZ58 and Q478 and QC72.The results showed that there were 6 different endosperm types among QC72 isogenic line and only 3 endosperm types among QZ58 and 478 isogenic lines.The hardness QC72 appears a series of continuous variations.The current of the remainder of litter weight is QC72 Q478 QZ58.The higher is liter weight of recurrent parent,the higher is it of its genealogical line.So it is important to chose a hard endosperm line as recurrent parent when corn breeding in Quality Protein Maize(QPM)

Key words: Isogenic line, SSR marker, Endosperm quality
