Qianfeng 103A
A new type of maintainer line and a pair of male sterile lines were bred by using a rice blast resistant maintainer line Digu B, an early maturing high-quality Yue 4B and a high-quality conventional rice.

Innovative technology is applied to the breeding of multiple excellent maintainer line germplasm materials by polymerization hybridization and multiple generations of backcross selection with male sterile lines
Aofu A
Since 2015, high-quality and high-yield early hybrid rice Aofuyou 655 has been successively bred and approved by Guangxi, high-quality early maturing late indica rice Aofuyou 383 has been approved by Hubei Province, high-quality and disease resistant late maturing middle rice Aoyou 818 has been approved by Guizhou, and Aofuyou 899 has entered the early maturing late indica continuous test and production test in Hubei Province, which will be approved in early 2017. Increasing the approval and promotion of new varieties of Aofuyou series will effectively solve the problems of long maturity and poor rice quality of early and late indica hybrid rice in China. The market development, promotion and application prospects are broad.
Qiang 11S Hongfeng 80S Xiongfeng S
Y58S, Xiangling 628S and Guangzhan 63S were used as genetic male sterile gene donors to polymerize and hybridize with the excellent materials of self selected indica japonica hybrid germplasm, and were bred directionally through such technical approaches as south-north shuttle planting, natural and artificial low temperature double pressure screening, resistance stress selection, combining ability and comprehensive detection of rice quality.
Tianan S
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.
