资源研究的目的是利用，资源分类也应围绕这一中心。据此，本研究根据栽培大豆品种资源的栽培区、栽培型、单株粒重、百粒重、生育期、抗病性（花叶病毒、霜霉病、灰斑病、孢囊线虫１号、３号）、抗虫性（食心虫）、株高、油分、蛋白质、叶形、花色及茸毛色，把东北三省（黑龙江、吉林、辽宁）１７７８份栽培大豆品种资源划分为１个区、１个型、５类、２５群、９９亚群、１６６３个类型。提出了栽培大豆品种资源分类的基本模式及今后的发展方向。 The purpose of resource research is to utilize and resource classification should also center around this center. Therefore, based on the cultivated area, cultivation type, grain weight per plant, grain weight, growth period, disease resistance (mosaic virus, downy mildew, gray spot disease, cyst nematode 1 , 1778 cultivated soybean cultivars in three northeastern provinces (Heilongjiang, Jilin and Liaoning) were divided into 1 area, 1 5 types, 25 groups, 99 subgroups, 1663 types. The basic mode of classification of cultivated soybean varieties and their future development are proposed.
