We can divide pecan varieties in two sections. Ungrafted and Grafted varieties.

Ungrafted (Seedlings):

These trees are good landscape trees. Their nut quality is range from poor to acceptable. If your primary objective is nuts than you should consider grafted varieties.

Grafted (Improved) Varieties:

If you are a professional grower and focused on nuts and kernel quality then you should plant grafted trees.  They comes in various nut size and quality.  Grafted varieties can be divided in two main sub categories.  Type I and Type II. In simple terms early and late. Pecan trees have both male and female flowers (pollen and receptor flowers) on the same tree, but the two are not always in sync. So cross pollination is must to yield quality nut production and health of pecan trees.
