| Abstract: | Ben S,derived from the cross between Guangzhan 63 S,a photoperiod-and thermo-sensitive genic male sterile(PTGMS)line,as the female and Tianfeng B,a maintainer line,followed by a backcross of its desirable male sterile F3 plants to Tianfeng B and years of directional selection on target traits,is a new TGMS line in rice.It has excellent comprehensive agronomic traits,low critical sterility-inducing temperature,good flowering habits,high outcrossing and seed-setting rate and strong combining ability.In July,2018,Ben S was technically identified in Guangdong Province. |
