摘要
辽宁省９０４份大豆品种若干性状的研究结果表明，以叶面积、株高、单株荚数、单株粒数、单株产量５个性状的耐瘠指数值相累加，按累加值大小将品种的耐瘠性分为五级：（１）高度耐瘠（４－４．５），（２）耐瘠（２－３．４９），（３）中度耐瘠（３．５－３．９９），（４）耐瘠性差（１．５—１．９９）．（５）不耐瘠（１．４９以下）。鉴定出一批优良的耐瘠种质资源。
Nine hundred and four soybean varieties from Liaoning Province were divided into five groups based on their tolerance to barren soils: highly-tolerant-tolerant;moderately-tolerant;poortolerant;and highly sensitive.The tolerance was estimated in a cumulative datum of several traits including leaf area,plant height.number of pods and seeds Per plant .and yield per plant.
