Virus-free budwood of sweet cherry varieties—Bing, Black Tartarian, Napoleon or Royal Ann, Black Republican, Deacon, and Lambert—have been propagated in experimental plantings at Davis. Sufficient fruit has been produced on the trees to determine trueness to variety. However, insufficient time has elapsed to obtain data on mature tree performance in California of the clones obtained from other states.

The above progress report is based on Research Projects No. 974 and 1478

The inspection of cherry orchards as part of the improvement program was by the Bureau of Plant Pathology of the California State Department of Agriculture

Queries concerning availability of virus-free bud wood should be addressed to the Department of Phonology, University of California, Davis, California
