The genetic parameters of life period and main agronomic traits of the 377 soybean cultivars were studied. The results show: (1) The new early-maturing and high-yield cultivars are expected by selecting according to the full life period, pod length, pod number pear plant and seed number per plant, the new big-seed cultivars according to the pod length and width. (2) The yield components are significantly different among the breeds of the different life period form. (3) The early-maturing breed has the highest variance coefficients of stem size and full life period; the middle-maturing breed has the highest variance coefficients of plant height, podding height, pod number per plant, seed number per plant and yield per plant; the late-maturing breed has the highest variance coefficient of pod length, pod width and hundred-seed weight. (4). The pod number and seed number per plant has lower hereditary capacities and higher genetic advances; the hundred-seed weight and yield per plant heve the higher hereditary capacities and lower genetic advances.
