The objective of this study was to elucidate the growth pattern and the adaptability of Glycine spp. under different crop seasons. Eight wild and cultivated strains/varieties belonging to five Glycine spp. were cultivated in the spring and fall crop seasons of 1988. Characteristics of dry matte accumulation were measured at successive growth stages of the plants and growth rates were determined. The growth rate of cultivated varieties and annual wild strains increased rapidly in early growth stage, but declined markedly during the late developmental period. On the contrary, the initial growth rate of the perennial wild strains was low, while the rate increased significantly as the plants developed. Therefore it is suggested that the growth pattern for the cultivated varieties and annual wild strains be named as dash-vigor type, and the perennial wild strains as sustained-vigor type. The seasonal differences in the pattern of dry matter accumulation were more significant for the cultivated varieties and annual wild strains than for the perennial wild strains. It appeared that the perennial wild soybeans could adapt themselves to diverse habitats much better than the annual strains/varieties.
