Abstract:Assessment, conversation and utilization on elite rice genetic resources in Guizhou were chiefly summarized during 1991 ~ 2000. The main points can be concluded that the Three Working and Managing Systems on Rice Genetic Resources in Guizhou had been established in the long course of research. Firstly, identifying and evaluating system is essential to study the characteristics of rice genetic resources according to botanical and biological trails. Secondly establishing reproduction system in ex - situ conservation combing with short storage in low temperature, and finally, information management system of genetic re-sources conserved in Guizhou was also formed on the base of their characteristic databases. These systems will be efficient to pro-mote the further researches.
