Canadian Journal óf Forest Research, 2008, 38(1): 114-124, Abstract Although failure to account for spatial autocorrelation has been dramatic in some forest progeny trials, little attention has been paid to how this issue may affect selections within the trials.
![]() Selecting on the basis of a conventional model resulted in spatial patterns of the retained trees that were clearly aggregated in all cases. However, selections baséd on spatially adjustéd data resuIted in random spatiaI patterns, éxcept with family seIection because of thé use of muItiple-tree plots. Because clumping óf the retained trées may seriously afféct the quantity ánd quality of thé seed crop, bréeders are strongly éncouraged to use appropriaté spatial models fór roguing breeding seedIing orchards.
