| Abstract: | He S, derived from a variant plant among a new rice variety introduc ed from Singpore, is a thermo-sensitive genic male sterile (TGMS) line of indic a type in rice. It is characteristic of good plant type, stable fertility altera tion, high stigma exsertion rate, strong pest resistance and good grain quality. It has another remarkable advantage of slight panicle enclosure, which can great ly decrease the dosage of GA 3 in its hybrid seed production. The hybrids of it showed strong heterosis in grain yield with big panicles and high seed setting percentage. It was technically identified and registered in Guangxi in July, 200 1. |
