Abstract：Two yellow-green leaf mutants 9110Gt and NCC-042 are used as cucumber（Cucumis sativus L.）materials to conduct phenotypic observation, genetic analysis and molecular marker verification. The results showed that 2 yellow-green leaf mutants were significantly different in morphology. Genetic analysis demonstrated that the 2 leaf color mutations were controlled by 2 different genes, and there existed complementary effect between these 2 genes. The result of molecular marker detection also confirmed this conclusion.
