Beacon apple tree (Malus domestica Borkh.) variants derived from gamma-irradiated scionwood on Columbia Crab seedling (CC) rootstocks were compared to both standard Beacon/clonal rootstocks, standard Beacon/Cc rootstocks and Columbia Crab seedling trees. Stem or root measurements of trees classed as induced spur-type dwarf variants/Cc rootstocks had larger bark to xylem ratios than trees from other growth habit classes. Stem and root bark to xylem ratios have the potential to be used as juvenile selection criteria in screening for spur-type dwarf variants in irradiation-exposed apple tree populations.
