1. Joint exploration for collecting Medicago in Argentina 1989 was planned by Agriculture, Forestry and Fisheries Research Council (AFFRC), and conducted by AFFRC Secretariat, Nat. Inst. Agrobiological Resources, Nat. Grassland Research Inst. of Japan and National Institute of Agricultural Technology (INTA) of Argentina. 2. The period of the exploration was 37 days, from January 14th till February 19th in 1989. It was maturity and harvest season of Medicago in Argentina, and so optimum period to collect seeds from fields and farmer's stores. 3. The expedition drove a car of INTA throughout all the course about 11, 000 km through the provinces of Cordoba, Santiago del Estero, Salta, Catamarca, La Rioja, San Juan, Mendoza, La Pampa and Santa Fe. These areas are located in from 25 to 38 degree of south latitude, and from lowlands to 2, 850 m elevation. 4. There were almost neither escaped nor weedy populations of Medicago in Argentina due to severe environmental conditions (drought, small animal, etc.). 5. One hundred and twenty nine seed lots were collected from pasture, meadow, field, and store of farmers, cooperatives, institutes, seed companies etc. They were mainly native strains (called ecotipo) and some bred varieties. 6. The seed lots taken from very salty fields in Santiago del Estero and high elevation pastures in Salta and dry meadow in La Pampa may be interested germplasm especially for salt, cold and drought resistance varieties respectively. The authors wish to express their sincere gratitude to Dr. K. A. Okada, Coordinator Genetic Resources Program INTA, Ing. Agr. A. G. Cragnoz, Coordinator Alfalfa Program INTA, Dr. E. Hijano, EEA Manfredi INTA, Dr. L. H. Ochoa, EEA Sanchago del Estero INTA, Ing. Agr. R. A. Neumann, EEA Salta INTA, Ing. Agr. H. Vicente, EEA Anguil INTA, and many coworkers in INTA for the arrangement and assistances of the collection tour. Furthermore the authors make a grateful acknowledgment to Mr. A. Nanbu, prime secretary of Japanese Embassy in Argentina, and Messrs S. Kamimura, M. Aoki, T. Ezuka, Japanese International Cooperation Agency in Argentina, for kindly supports during their stay in Argentina. |
