P50006×HCM

Using the inbred lines P50006 and HCM A.C. as parents, the F₂ generation population was constructed by artificial de-maleization. HCM A.C. is provided by Professor Philipp W. Simon of the University of Wisconsin, USA. P50006 is a high-carotene inbred line material selected by the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences after years of breeding. In late July 2007, the parents and F₂ generations were sown in the open field on the experimental farm of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences.
