Juvenile-Mature Correlations in Pinaceae and Implications for Early Selection

Juvenile-mature correlations in the literature were analyzed and found to be more predictable than may have been expected by those who have dealt with them. Age-age correlations except those involving very young ages, usually 1-3 years, can be estimated with reasonable accuracy by a single regression equation which applied to several species and studies. Applicability of the equation to genetic test situations may be possible. After predicting age-age correlations, optimum selection age was estimated for several economic rotations. These ages for 30- and 40-year economic rotations were 6 and 8 years respectively for the conditions specified. Forest Sci. 26:571-580.
