Photo-thermo-sensitive genic male sterile (P/TGMS) lines are precious resources for hybrid rice breeding. Using the newly discovered rice P/TGMS line 19XS as material, its breeding process, agronomic traits, fertility conversion characteristics, hybrid progeny fertility, and genotype were analyzed. The results showed that in Wuhan area (sown in early May), 19XS maintained a stable sterile state for more than 45 days from heading in early August to late September; a small amount of fertility conversion began to occur after October 3. In Hainan area (sown in late November, heading in early March), 19XS generally appeared fertile, exhibiting photo- thermo-sensitive fertility conversion characteristics. Genetic analysis indicated that 19XS is a new recessive genic male sterile line, and its sterility is not interfered with by the genetic background. The hybrid progeny of 19XS and Xiang 78S (19XS/Xiang 78S) exhibited excellent agronomic traits, including compact plant type, large panicles with numerous grains, and high seed setting rate. Gene chip detection results showed that both 19XS and 19XS/Xiang 78S contain the thermo-sensitive male sterile gene TMS5. These findings provide a new material basis for hybrid rice breeding.
