A relatively low number of weed species have evolved resistance to auxinic herbicides despite their use for almost 70 years. This inheritance study with two Raphanus raphanistrum populations multiple-resistant 2,4-D and the ALS-inhibiting herbicide chlorsulfuron determined the number of genes and genetic dominance of 2,4-D resistance and investigated the association between traits conferring resistance to the two herbicide modes of action. Levels of 2,4-D phenotypic resistance and resistance segregation patterns were assessed in parental populations, F and F families.
尽管使用了近 70 年，但具有抗激素除草剂特性的杂草物种相对较少。本研究通过对两个具有抗 2,4-D 和 ALS 抑制剂类除草剂氯磺隆特性的萝卜属种群进行遗传分析，确定了 2,4-D 抗性的基因数量和遗传优势，并研究了两种作用模式的除草剂抗性特性之间的相关性。在亲本种群、F 和 F 代中评估了 2,4-D 表型抗性水平和抗性分离模式。
