Abstract:

The grey relational degree between starch content and characters in CIMMYT Pob45, Pob46, Pob69, Pob70 was analyzed in this article. The grey relational degree order is ranged from maximum to minimum: ear weight> seeds of line>100-kernel weight>ear wide> ear length >Lines of ear. The corn starch mainly exists in the endosperm cell, but the endosperm weight occupies the corn grain over 90%.Therefore, a high-starch corn inbred would be chosen from the more seeds of line and heavy 100-kernel weight in breeding materials.
