Research Achievements

Since the foundation of CNRRI,over 50 rice varieties with high yielding, good grain quality and pest resistance have been released.

Xieyou 9308,three-line rice hybrid, showed new high-yielding record of 12.2 t/ha in single cropping.

Zhong 9A, CMS line with characterisics of good quality and high outcrossing rate is widely used in hybrid rice breeding.

Shanyou 10 and other major three-line rice hybrids were grown in China with annual planted area over 1.33 millon ha.

Zhongjian 2, an indica rice variety with excellent grain quality was released commercially.

The plant growth regulation technique has been wildly applied in hybrid rice production with annual acreage of 8 million ha.

A T-DNA inserted rice mutant population is being constructed smoothly based on an efficient transformation system.

Hyphal fusion in Magnaporthe grisea can change the lineages and virulence.

Micro-organism agent(Kebaimei-Mycoherbcide of barnyard grass) is being developed.

The mechanism of signal prodution of rice planthopper has been clearly explained.

Rice-duck farming system can greatly increase
rice farmers' income and promote sustainable development of rice production.

QTL analysis indicated that yield traits
in rice are conditioned by complex gene interaction nets.
