Cytological studies on male sterile line CMS_ (3411-7) with Polcms (B.napus L.) cabbage (B. campestris L.ssp. Pekinensis (Lour.) Olsson.var.cephalataTsenetLee.) Showed that: (CMS_ (3411-7) anther development was blocked in the stage of sporogenous cells and did not form anther chamber. The microscopic observation of the microscopic pollen at the late flowering stage confirmed the availability of this system.
