Abstract: The experiment was conducted with a new high oil corn species to study the correlation and path analysis among grain oil content, grain structure and different levels of nitrogen and potassium. The results showed that embryo/ endosperm area had the greatest effect on the grain oil rate which its path coefficient(P3y)was 3.7557,the embryo area which its P2y was 1.8027 had less effect than embryo/ endosperm area on the grain oil rate, while the endosperm area (P2y = -0.0358) had the least effect. The different levels of nitrogen and potassium had some effects on corn grain oil content by changing the grain structure of embryo/ endosperm area.
