The present specification discloses a cytoplasmic male sterile Brassica rapa plant having a growth ability equivalent to that of a Brassica rapa plant having a normal cytoplasm or a progeny of the cytoplasmic male sterile Brassica rapa plant. In existing-cytoplasmic-male-sterile B. rapa plants, the compatibility between the nuclear genome and mitochondrial genome is insufficient. Therefore, the existing-cytoplasmic-male-sterile B. rapa plants have the problem that the growth ability is deteriorated compared with those of B. rapa plants having a normal cytoplasm. With the present invention, it is possible to improve the deterioration of growth ability which has been observed in the conventional cytoplasmic male sterile B. rapa plants and provide a cytoplasmic male sterile Brassica rapa plant having an improved growth ability.
