China National Center for Rice Improvement

Established in 1998, China National Center for Rice Improvement (CNCRI) was designated to accelerate the exploration and innovation of new breeding materials and rice germplasm, and eventually to develop high-yielding, high-quality and insect, disease resistant rice varieties. Through network of nine branches, CNCRI is engaged in organization and coordination of rice breeding programs and integrated research programs throughout China, carrying out scientific and technological research as well as basic theory studies involving rice breeding and production. It also concentrates on collection, evaluation, innovation, conservation and exchange of rice germplasm resources.


1. Germplasm Evaluation

Collecting, identifying and examining international and domestic germplasm resources; Managing medium and long-term germplasm bank and building core germplasm bank; Conducting preliminary appraisals on grain quality and insect, disease resistance of superior parental lines screened and identified by CNCRI.

2. Genetics and High-tech Studies

Mapping and characterizing genes of interest in superior germplasm resources using classical genetic analysis in combination with molecular-level genetic methodologies; Elucidating inheritance and mutation mechanism of agronomic important traits and new useful traits in cellular and molecular levels;

Developing superior germplasm and parental lines, exploiting new breeding technologies and methods through combination of biotechnologies, conventional techniques and other scientific tools.

3. High Grain Quality and Multiple Resistances

Screening, identifying and developing new resistant materials;

Developing insect and disease resistant parental lines through pyramiding single resistant genes of diversified breeding materials;

Developing superior breeding materials designated for various purposes.

4. Super High-Yield Breeding

Constructing ideal plant types and developing materials for super high-yield breeding;

Exploiting and developing materials of high photosynthetic efficiency.

5. Super High-Yield Rice Breeding with High Photosynthetic Efficiency Characters

Screening, identifying and developing new breeding germplasm designated for three-line rice hybrids;

Developing new indica and japonica PGMS lines;

Exploiting new wide compatibility resources and further developing wide compatibility CMS lines and restorer lines;

Developing rice materials for apomixis.

6. Radioactive Breeding

Creating new materials and germplasm through various induced mutation methods;

Developing, identifying, conserving and genetic analyzing mutation germplasm;

Exploring new methods and tools for induced mutation and elucidating the mutation mechanism;

Developing new rice varieties through radiation induced mutation breeding
