Abstract
A SHOUT note issued by Science Service of Washington, D.C., announces the discovery by Dr. G. G. Hahn of a new variety of red currant resistant to the uredo- and teleuto-spore stages of Cronartium ribicola, the white pine blister rust fungus. This organism is heteroacious, spending its life-history on two distinct host plants. Currants and gooseberries are the summer hosts, whilst the secidial stage is spent upon white pine (Pinus strobus) in the winter. Many districts in America regard the white pine as then1 principal source of wealth, and so both wild and cultivated currants and gooseberries were eradicated completely. This caused much grief and expense to gardeners, but removed the necessary summer hosts of the fungus, and effectively controlled the disease on white pine. The new disease-resistant red currant is known as ‘Viking’; it provides fruit of good quality, and promises to withstand drought as well as to resist disease.
