Utilization of drought-tolerant germplasm in rice resources in Guangxi

The present paper is an attempt to discuss significance and primary achievements of utilizing the drought- tolerant germplasm in rice resources in Guangxi from the point of crop breeding and genetic resources. The main problems related to their exploitation in breeding and their causes have been analyzed. According to the studies, researches on drought-tolerant rice and upland rice breeding have been suggested to be paid more attention in future. In order to provide references for achieving grain security, exploitation of abundant rice resources in Guangxi is recommended, and innovations in concepts and technologies of rice breeding and drought-tolerant cultivation technologies have been discussed.
