Breeding and Application of PTGMS Line 761S in Rice
761S,derived from the cross of Y58S(as female parent)and Luliangyou 996(as male parent),is a photoperiod-thermo-sensitive genic male sterile(PTGMS)line in rice developed by directional selection in male sterility under the natural low temperature conditions in Hainan or with the treatments of artificial low temperature water irrigation over eight generations of four years.It is characteristic of desirable agronomic characters,low critical sterility-inducing temperature,high outcrossing rate,high seed yield in multiplication,and fine grain quality.In August 2023,761S and its hybrid combination Guliangyou 99(761S/R2099)were both approved by Hubei Crop Variety Appraisal Committee.
