Two line and three line sterile lines with independent property rights
With "Y58S" as the nuclear sterile gene donor and self selected indica japonica hybrid germplasm materials, Tian'an S, a high-quality photo thermo sensitive genic male sterile line with early maturity and multiple panicles, was bred directionally. In 2015, it passed the fertility identification of China Rice Institute.
The sterility is stable, and the starting temperature of fertility transition is low,
The whole growth period is 4-5 days longer than that of plant 1S,
