The objectives of this paper are to study the genetic variability of seventeen quantitative characters including growth period, yield and mechanical harvesting of local soybean varieties in lower Yangtze and Huai valleys. The estimates of genotypic variance, genotypic coefficient of variation, heritability and expected genetic advance of these characters were calculated, in which the potentials and expected effects of selection from the natural population of these varieties were clearly indicated. From this study it is shown that the genetic resources of quantitative characters of these local varieties of soybeans are very abundant, that the simple selection is still one of the important methods in soybean breeding, and that to study the local varieties with the methods of quantitative genetics is of great importance both in theory and practice in soybean breeding.
