水稻育种的实践证明,突破性的成就取决于关键性资源的开发和利用。如在矮化育种中主要利用了具有矮秆基因(sd_1)品种矮脚南特和矮仔占等,才出现了今天这么庞大的衍生系统,这对浙江省的水稻育种和生产作出了巨大贡献。然而在此基础上育种要有个新的突破,就必须开发新的关键性资源,不断导入新的优良基因,以增加遗传的多样性,避免遗传因素的单一性和脆弱性,并要提高育种工作的科学性和预见性,以增
The practice of rice breeding has proved that breakthrough achievements depend on the development and utilization of key resources. Such as dwarf breeding (dwarf Nanantai and dwarf Aberdeen), dwarfing gene mainly used (dwarf gene), such a large derivative system appeared today, which made a great contribution to rice breeding and production in Zhejiang Province . However, on this basis, breeding should have a new breakthrough, we must develop new key resources, and constantly import new good genes to increase the genetic diversity, to avoid genetic unity and vulnerability, and to improve breeding Scientific and predictable work to increase
