【摘要】 从贵州大豆品种中随机抽取138份进行脂肪氧化酶测定、豆奶加工试验和品质、农艺性状鉴定。结果发现了31份脂氧酶缺失品种（其中包括2份育成品种），占鉴定总数的22．46％，包括缺失Lox2，Lox3和Lox2.3几种类型，以缺失Lox3类型较多。脂氧酸缺失大豆的分布以南部最多，北部最少，缺失类型则以中部最丰富。脂氧酶缺失品种的数量随着原产地大豆生长后期雨量的增多和温度的升高而增加，随海拔和纬度的增高而减少。更多还原

【Abstract】 138 ramdom samples of Guizhou soybean varieties were identified for lipoxygenase (lox),tested for soybean milk and appraisedfor quality and agronomical characters. 31 of those were lacked in lox2,lox3 and lox2. 3,most of them were lacked in lox3,which ac-counted for 33. 46per cent of total samples. The number of soybean varieties lacking Lipoxygenases was the most in south Guizhouand the less in the North. Kinds of lacking varietis was the most in the middle area in Guizhou. The number of local varieties lack-ing lox increased with the adding up of rain fall and raising of temperature in soybean lategrowth period, and reduced with raising inaltitude and latitude wheae soybean grew.更多还原
