    Abstract:

    Carrot male sterility enables the utilization of hybrid vigor of the crop. Yet the presence of seed hairs of carrot seriously affects the quality and efficiency of seed sowing， and it is usually necessary to remove the seed hairs before sowing. Male sterile material with hairless seed is important for carrot genetic breeding. Carrot Wuye-MG has typical petaloid male sterility and produces hairless seed， was obtained through generations selection from the crossing between the male sterile Wuye-BY selected from the wild carrot Wuye in Hongshan area of Wuhan City， and the selected hairless-seeded Wuye-hairless. In this study， Wuye-MG plants were observed to be dark green， with glabrous and hairless leaves， petioles and stems， and when pollinated by wild carrot Wuye or cultivated carrot Kuroda Gosun， produced fertile hairless seeds， which needed shorter time for germination than either Wuye or Kuroda Gosun. In the fertility mitochondrial gene， Wuye-MG contained the short segment of atp6 gene， but not the long segment of atp6 gene.
