摘　　要：从作物育种和遗传资源学角度探讨了广西稻种资源耐旱种质利用的重大意义和主要进展,分析了广西稻种资源耐旱种质利用存在的主要问题及其原因,提出今后应重视和实施水稻耐旱育种和旱稻育种,充分利用广西丰富的稻种资源,创新抗性育种理念、育种技术、抗性品种及耐旱栽培技术,为保障粮食安全提供参考。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.
