Abstract

Danyu502 is a single cross maize hybrid which was bred in Dandong Academy of Agricultural Sciences by crossing Dan1705 as female parent and Dan765 as male parent.The results of regional tests in Liaoning province from 2005 to 2006 showed that Danyu502 can increase 6.4% grain yield more than the hybrids using in production and has the characters of wide adaptation,resistance to multi-diseases,lodging and drought,high and stability yield,medium maturity,high quality and without side superiority.Danyu502 is applicable for Northern spring maize plantation area.
