Since 1935, the author has continued studying native (primitive) varieties of several kinds of crops cultivated in localities of unfavorable natural conditions. He has succeeded in breeding a new wheat variety resistant to strongly acidic soils, as well as other new ones highly resistant to drought, each out of those native to Tottori Prefecture. In the present report, the results of his investigations were referred to that were made on a climbing variety of Adsuki bean, one of the native strains found in Tajima District, Hyogo Prefecture, and in the reclaimed lands in Tottori refecture, during the years 1949 and '50. It was observed that on highly acidic soil, which was remarkably short of available phosphoric acid content (as shown in Table 1), the climbing variety grew invariably more vigorously than the ordinary Adsuki variety, without regards to the time of seedling tested (as shown in Tavle2, 3 &4). According to the results obtained, the author advocated the importance of studying native varieties of crops grown in localities of unfavorable natural conditions.
