通过R15 0 ,T89,T2 4 2及 982 9模型的建立 ,遗传育种模型建立的技术策略、技术路线、性状操作、育种选择等 ,从一个角度体现了水稻定向育种的定向性和快周期性。还就建立与应用遗传育种模型的理论与实践等方面进行了讨论
Through the establishment of R15 0, T89, T2 4 2 and 982 9 models, the technical strategy, technical route, trait manipulation and breeding selection established by genetic breeding model reflect the directional and fast periodicity of directional rice breeding from one aspect. The establishment and application of genetic breeding model theory and practice are also discussed
