Interpretive Summary: Genetic resources of temperate berry crops were collected 7 to 27 July 2004, in Hokkaido, under a bilateral agreement between the United States and Japan. This expedition was a collaborative effort between the United States Department of Agriculture (USDA), the Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF), the University of New Hampshire, and Akita Prefectural College of Agriculture, Japan. Additional assistance was provided by the Hokkaido Governmental Plant Genetic Resources Center, several Forest Research Stations of the Hokkaido University, and private botanists. The expedition obtained 100 items encompassing 29 berry crop species. In all, 84 seedlots, and 23 plants were obtained. Kiwifruit, strawberries, currants, gooseberries, raspberries, black raspberries, blueberries, and cranberries were obtained.Plant and seed accessions from this trip are preserved and distributed from the USDA ARS National Clonal Germplasm Repository in Corvallis, Oregon, and from MAFF. Strawberry was the target species for this expedition, so the trip was planned for July. Multiple samples of the two main wild Japanese species were obtained during their prime ripening time. Raspberry, gooseberry, and blueberry fruits ripened later in the summer but were collected early. Unfortunately, seeds of some of these accessions proved to be immature or non-viable upon extraction. We suggest that expeditions to collect these other fruit species should be planned for late August. Morphological and molecular evaluation of collected germplasm is underway at the USDA ARS Corvallis Repository and at the University of New Hampshire.

Technical Abstract: Genetic resources of temperate berry crops were collected 7 to 27 July 2004, in Hokkaido, under a bilateral agreement between the United States and Japan. This expedition was a collaborative effort between the United States Department of Agriculture (USDA), the Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF), the University of New Hampshire, and Akita Prefectural College of Agriculture, Japan. Additional assistance was provided by the Hokkaido Governmental Plant Genetic Resources Center, several Forest Research Stations of the Hokkaido University, and private botanists. The expedition obtained 100 accessions encompassing 8 genera, and 29 species. In all, 84 seedlots, and 23 plants were obtained. The genera collected included: Actinidia, Fragaria, Lonicera, Morus, Ribes, Rubus, Sambucus, and Vaccinium. Plant and seed accessions from this trip are preserved and distributed from the USDA ARS National Clonal Germplasm Repository in Corvallis, Oregon, and from MAFF. The target genus for this expedition was Fragaria, so the trip was planned for July. Multiple samples of the two Japanese diploid strawberry species, Fragaria iinumae Makino and F. nipponica Makino (synonym = F. yezoensis H. Hara) were obtained during their prime ripening time. Ribes, Rubus, and Vaccinium fruits ripened later in the summer but were collected when fruit were observed. Unfortunately, seeds of some of these accessions proved to be immature or non-viable upon extraction. We suggest that expeditions to collect these genera should be planned for late August. Morphological and molecular evaluation of collected germplasm is underway at the USDA ARS Corvallis Repository and at the University of New Hampshire.
