(1992) thoughtfully evaluated the application of molecular markers in forest tree breeding for marker aided selection. The purpose of their paper was to emphasize the limitations and shortcomings of marker-aided selection particularly in conifers. They argued that studies of quantitative trait loci identified in agronomic crops, which have significant utility (e.g. Stuber, 1992; Stuber et al., 1992), are of little relevance to assessing the potential for marker aided selection in populations of forest trees, and that the near term usefulness of molecular markers for forest tree breeding will be limited. The major barriers to application included cost, the lack of association of markers with traits across breeding populations due to linkage equilibrium, variation in expression of loci affecting quantitative traits due to differences in genetic background, genotype environment interactions, and stability of marker-trait associations over multiple generations. In addition, Strauss et al. (1992) noted that marker-aided selection would be most useful for within family selection, where the economic values of the traits are high, the trait heritabilities are low, and where markers are able to explain much of the genetic variance. However, they argued that important traits in forest trees such as wood volume, are likely to be controlled by large numbers of genes with small effects, and therefore, are unlikely to have useful marker trait associations.}, booktitle={Genomes of Plants and Animals: 21 Stadler Genetics Symposium}, publisher={Plenum Press,  NY}, author={O'Malley, D.

Batsch] cultivar Pillar shows variegation in anthocyanin production in both vegetative and reproductive tissues. This phenotype is heritable, although the degree of variegation differs with genetic background in progency of outcrosses. Genetic evidence supports the hypothesis that the unstable phenotype is caused by an active transposable element. Reversion to wild-type anthocyanin production in Pillar gave rise to mericlinal and periclinal chimeras of pigmented and nonpigmented tissues. Reversion events in LI and Lll histogenic cell layers of Pillar produced different phenotypes that could be easily distinguished. The reversion rate in the LI and LII layers was determined using the rate at which periclinal mutant buds and shoots were formed. The reversion rates to wild type in the LI and Lll histogenic layers ranged from 0 to 10−2, and from 0 to 3.6 × 10−2 mutations per branching event, respectively. In families where reversion rates in the LI and LII histogenic layers could both be measured, the reversion rate in the LI layer was about fourfold greater than in the Lll.}, number={3}, journal={Journal of Heredity}, publisher={Oxford University Press (OUP)}, author={Chaparro, J.
