Abstract

Age-related trends in narrow-sense and family heritabilities for black walnut height and dbh from a southern Illinois open-pollinated progeny test are evaluated through age 20 years. Narrow-sense heritability for height tends to be relatively stable between ages 10 and 20 at 0.55 - 0.65 with similar patterns and values for family heritabilities for both height and dbh. Individual phenotypic age-age correlation coefficients increased from approximately 0.1 at age 1 to 0.8 at age 8 and remained above this level through age 20.
