| Abstract: | The cold tolerance of rice is an important index to resist low temperature injury.Among them,cold tolerance in bud stage is an important period of cold tolerance in rice.In this study,a number of rice varieties from different regions were tested for cold tolerance at budding stage.The results showed that 15 high-quality rice varieties showed extremely weak cold tolerance at 14℃for 7 days."Longdao 18"and"Tonghe 66"showed extremely strong cold tolerance,while"Jiudao 68"and"Jigeng 511"showed strong cold tolerance.In the bud stage test,all varieties had strong cold tolerance at bud stage. |
