Ensure yoor object does not have more than one material or any texture that could cause theis
Remove any double vertices (select all vertices and W / Remove Doubles)
Recalculate face normals (select all faces and Ctrl+N)

thank you, it was the recalculation!! question solved!! thank you very very much! lena
