The interval sowing experiments showed that 291S was a photo-thermo-sensitive male sterile line, which showed part fertile under short-day and low-temperature conditions when autumn sowing, showed high sterile under long-day and high-temperature conditions when spring sowing. The self-multiplication ability and sterility of 291S can be improved through selection effectively. The pistillody of stamens of 291S could be induced under certain photoperiod and temperature condition.
