通过诱变和离体培养技术，从花生两个不同亲本中分离到两个具有类似病斑叶性状的突变体。发现两种突变体中的叶片叶绿素含量急剧降低。F-2和F-3代正常性状和突变性状的分离模式符合13：3的比例，表明突变体中的疾病病变模拟性状是由于抑制基因的作用。这两个突变体是等位的疾病模拟性状。
In groundnut, two identical mutants with disease lesion mimic leaf trait were isolated independently from two different parents through induced mutagenesis and in vitro culture technique. The leaf chlorophyll content in both the mutants was found to be drastically reduced. The segregation pattern in the F-2 and F-3 generations for normal and mutant traits fitted a 13:3 ratio, indicating that the disease lesion mimic trait in the mutants was due to suppressive gene action. Both mutants were allelic for the disease mimic trait.
