Development and Use of Juvenile-Mature Correlations in a Black Walnut Tree Improvement Program

Diameter, height and volume at various ages were determined by stem analysis. Character used for early selection should have the high juvenile - mature correlations. The earliest age for selection should maximize the product of the juvenile mature correlation and the selection differential at that age.
