Early Orange Mass 400, Early Orange Mass 402, and Late Orange Mass 404: high-carotene cucumber germplasm.

摘要

Early Orange Mass 400 (EOM400), EOM402 and Late Orange Mass 404 (LOM404) were derived from crosses between US pickling cucumber lines (Cucumis sativus var. sativus) and the orange-fruited C. sativus var. xishuangbannesis from China. After 7 cycles of phenotypic recurrent selection for orange flesh colour beyond the BC1 generation, fruits of LOM404 contained total carotenoids of 1-15 mg/kg FW. EOM400 and EOM402 were derived from 5 generations of self-pollination and selection and 1 generation of mass selection for immature fruit colour, and fruits contained 1-25 mg/kg FW of carotenoids.
