Its pollen abortion type was different from others. From the studies of test-crossing, back-crosses and sib-crossing, sterile and fertile plants segregated in a 1:1 ratio in the descendant populations. When the sterile plant was used as female parent and crossed to normal variety, sterile and fertile plants segregated in a 1:1 ratio in the descendant populations also, and no sterile plants cound be separated from fertile plants. All of the results proved that the male sterility of S221 is controlled by one pair of dominant male sterility gene.
