根据镇稻系列品种的选育经验和多年的育种实践,得出了以下几点育种经验:①通过合理利用优良亲本,进行科学配组创造变异;②材料抉择时综合性状协调是育种的关键;③掌握好苗期看长势、中后期看抗性、后期看熟相、考种看籽粒等方法进行选择。并对进一步改良粳稻品种提出了以下几点策略:①广泛征集、鉴定和利用优良种质资源,同时注重加强优异种质创新,不断提高育种基因库整体水平;②杂种优势的利用;③抗纹枯病、抗除草剂等新种质的创新与应用;④水稻育种栽培理论的集成与应用。
According to the breeding experience of paddy rice series and breeding practice for many years, the following breeding experiences have been obtained: (1) Through the rational use of elite parents, sci-tech groups are created to create variation; (2) Coordination of comprehensive traits is the key to breeding; ③ grasp the seedling to see growth, see the resistance in the late, late to see cooked phase, test seed see other methods to choose. And put forward the following tactics to further improve japonica rice varieties: (1) Extensive collection, identification and utilization of excellent germplasm resources, pay attention to strengthening the innovation of excellent germplasm, and continuously improve the overall level of breeding gene pool; (2) Utilization of heterosis; (3) Blight, herbicide and other new germplasm innovations and applications; ④ rice breeding and integration of the theory and application.
