BREEDING WOODY ORNAMENTALS AT EAST MALLING, WITH PARTICULAR REFERENCE TO SAMBUCUS NIGRA
In Sambucus nigra crosses have been made among 'Aurea', 'Guincho Purple', and 'Laciniata' and between two first generation selections. The resulting segregations indicate that red leaf colour and yellow leaf colour are attributable to dominant genes, Pur and Aur, and laciniate foliage to a recessive gene, lac. Red leaved individuals usually have green, or yellow, flecks; this flecking may be caused by a transposon. Some selections combining laciniate foliage with red or yellow leaf colour or both may have sufficient ornamental merit to be grown in place of Japanese maples.
