Abstract: To improve the cold tolerance of rice and enrich its resources of germ plasm in cold regions. 108 varieties (materials) from international network for genetic evaluation of rice (INGER) were planted in the twenty-fourth and twenty- fifth international rice cold tolerance nursery(IRCTN) in cold regions for the first time. The appraisal showed that 20 of the varieties (materials) have high cold tolerance in seeding, 49 of the varieties (materials) have high cold tolerance in tillering and 20 of the varieties (materials) have high cold tolerance in spikelet. 14 of the varieties (materials) have high cold tolerance in the whole growth.. These varieties (materials) will supply rich in excellent natural resources of seeds and expand cold tolerance parent materials.
