Caucasia, one of the eight centers of origin of cultivated crops according to Vavilov's theory, is located at the same latitude as Hokkaido, the most northern island of Japan. It was anticipated that this expedition would enable to collect a wide range of legume and grass germplasm useful for forage breeding. The team collected 184 samples. They included 104 samples of forage legume and 80 of forage grass. Legume species consisted of 47 accessions of Trifolium, 15 of Medicago, 14 of Galega, 11 of Melilotus and a small number of other genera. Grass species consisted of 18 accessions of Dactylis, 16 of Lolium and others. Most of the samples were collected at roadside area and natural grassland. In several sites we collected eight or nine species. We were impressed by the diversifcation of species. Since a large number of cattle were feeding on grasses in the mountains and towns, it was difficult to collect seeds. We were able to collect seeds only from plants surrounded by thorny plants at some sites. We explored only about one third of Caucasia during this expedition because other area was in danger. Some species, Trifolium pratense and Dactylis glomerata, occured over a wide range of elevation from 0m to 1,700m. They were good for tests to analyse the relationship between cold hardiness and the elevation. We obtained one sample of Galega orientalis and collected 14 Galega samples. Plants of Galega orientalis are used for feed of cattle in Russia. It is valuable to test the adaptability of Galega at Hokkaido.}, pages = {201--206}, title = {ロシアカフカス地方における牧草遺伝資源の探索収集}, volume = {10}, year = {1994}, yomi = {ヤマグチ, ヒデカズ and モンマ, エイヒデ} }
