ABSTRACT Resistance to brown stem rot of soybean has been identified and utilized in cultivar development and germ plasm enhancement. However, little is known about the nature of resistance to this disease. In an attempt to better understand the resistance mechanism by locating the tissue or tissues responsible for resistance, reciprocal grafts were made between brown stem rot-resistant and -susceptible genotypes including near-isogenic lines for resistance gene Rbs2. Results of brown stem rot evaluation of grafted plants indicate that brown stem rot resistance is conditioned by the root in all resistance sources evaluated.
大豆对褐茎腐病的抗性已被鉴定并应用于品种选育和种质改良。然而，人们对这种疾病的抗性本质知之甚少。为了通过定位负责抗性的组织或组织来更好地了解抗性机制，在包括携带抗性基因 Rbs2 的近等基因系的褐茎腐病抗性和敏感基因型之间进行了相互嫁接。嫁接植株的褐茎腐病评价结果表明，在所评价的所有抗性来源中，根是决定褐茎腐病抗性的条件。
