Effect of number of annual rings and tree ages on genomic predictive ability for solid wood properties of Norway spruce

Table 1 Trait heritability, predictive ability (PA) and predictive accuracy (PC) Predictive accuracy (PC) for density, MFA and MOE cross-sectional averages at tree age 19 years, for their proxies on the stems without removing the bark at tree ages 21 and 22 years. Standard errors are shown in within parenthesis
