Abstract:
Few studies have partitioned the variability
in performance of a given cultivar between the
effects of seedling rootstock heterogeneity i.e.,
the genetic influence of the rootstock, and
edaphic factors.
The relative contribution of
genetic and environmental sources of variation
to tree performance varies with orchard soil
heterogeneity and the genetic heterogeneity
among seedlings within species used as rootstocks.
Identification and propagation of superior rootstocks, may greatly increase productivity in selected tree fruit species.
