Its pollen abortion type was dif- ferent 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
