Juvenile-Mature Correlations in Sycamore

Genetic and simple correlations for five seed traits, two nursery traits, and four early field traits were made with fifth year DBH, height, dry weight, and volume in a sycamore progeny test. Germination value and first year root-collar diameter were identified as potential early selection traits for increasing gain per unit time in fifth-year volume. Families that showed good rank stability over time were also observed as stable over progeny test locations. Selection for both stability and performance may be the most desirable strategy for advancedgeneration breeding programs. Additional keywords: Platanus occidentalis, early selection, stability.
