| Abstract:
There has been a recent resurgence of interest in the use of native North American plum species in variety and rootstock development programs primarily as a source of disease and pest resistance. Recent variety releases by Auburn University in Alabama and the USDA-ARS program at Byron, Georgia have utilized native plum materials to improve resistance to several important diseases of plum in the Southeast United States, including bacterial canker (Pseudomonas syrinqae pv. syrinqae [van Hall]) and plum leaf scald (Xylella fastidiosa [Wells et al.]). Native plum derived materials also appear to be a source of resistance to peach tree short life (PTSL) induced by the ring nematode (Criconemella xenoplax [Raski] Luc. and Raski) and Clitocybe root rot (Armillaria tabescens [(Scop) ex. Fr.] Dennis et al.). Selections are undergoing further screening at the USDA-ARS laboratory at Byron, Georgia for possible use as rootstocks for other Prunus species. | |
