1 Two-generations pedigree involving 524 plus trees and their open-pollinated (OP) 2 progenies were jointly studied to estimate parent-progeny correlation and heritabil-3 ity. Three wood traits (wood density, MFA, and MOE) were determined by SilviS-4 can in one ramet per plus tree and 12 OP progenies. Three ramets per plus tree and 5 12 OP were also measured with two indirect methods, Pilodyn and Hitman. The 6 overall correlation between OP-based breeding values and plus tree-based pheno-7 types was low to moderate for all traits. The correlations between the phenotypic 8 values of the mother trees and the breeding values estimated on their half-sib pro-9 genies are low to moderate. Reasons for this may be experimental errors in progeny 10 trials and lack of experimental design in archives, contributing to the parent and 11 progeny correlation. The management practices in the archive may contribute more 12 to such low correlation. Offspring progeny heritability estimates based on SilviScan 13 measurements were higher than parent-offspring regression using one single ramet 14 from the archive. Moreover, when three ramets were measured the parent-offspring 15 regression heritability estimates were higher than those based solely on progeny 16 data for the Pilodyn and Hitman on the standing trees. The standard error of the 17 heritability estimates decreased with increasing progeny size.18 19
