Technical Abstract: From August 5 through 25, 2001, a joint American-Rusian plant collecting expedition explored the Primorsky and Khabarovsk Territories of eastern Siberia to obtain genetic resources of temperate fruit and nut crops. Participants included staff from the U.S. Department of Agriculture, Agricultural Research Service, National Clonal Germplasm Repository (USDA, ARS, NCGR) in Corvallis, Oregon; Rutgers University, Philip E. Marucci Center for Blueberry and Cranberry Research and Extension, Chatsworth, New Jersey; Vavilov All-Russian Research Institute of Plant Industry (VIR), St Petersburg and the Far East Experiment Station (FEES), Vladivostok, Russia. More than 105 seed and Clonal samples representing 31 temperate fruit and nut species and 16 genera ere collected. Septoria leaf spot [Mycospharella ribes (Fckl.) Feltg.], powdery mildew [Sphaerothecia mors-uvae (Scw.) Berk.], and white pine blister rust (Cronartium ribicola J.C. Fisch.) were observed at three localities on two black currant species. Blind buds were observed on red currants. In Vaccinium we observed a fungal infection similar to cottonball [Monilinia oxycocci (Woronin) Honey], within fruits of lingonberry (V. vitis-idaea L.) in both Primorsky and Khabarovsk Territories. Seeds and plants from the expeditions were divided and the genetic resources were assigned ex situ preservation at the VIR stations in Vladivostok and St. Petersburg, Russia, and the USDA, ARS, NCGR in Corvallis, Oregon.
