摘要
水稻育种由经验育种向精确育种转变。在此过程中,适于现代育种的需要,由品种溯源示踪及按照育种路线图进行现代新品种创造,两种示踪技术逐渐发展起来。采用跨组学技术,包括基因组、转录组、蛋白组、代谢组、表型组等,结合常规育种技术、品种亲本溯源,开展了基于跨组学技术的育种示踪研究;结合‘津稻294’‘津原89’等新品种的选育示踪,发展了"骨干品种溯源、优化品种设计、综合技术运用"的育种策略,通过育种实践验证,证明新时期育种可以实现育种的定向性和快周期性。
Rice breeding is being transformed from experience breeding to precision breeding.In this process,two tracing techniques,tracing the origin of varieties and creating new varieties according to the breeding roadmap,have gradually developed to meet the needs of modern society.Using trans-omics techniques,including genome,transcriptome,proteome,metabolome and phenotype groups,combined with conventional breeding techniques and parental tracing of cultivars,a trans-omics-based breeding tracing study was carried out.Combining with the tracing of new cultivars such as‘Jindao 294’and‘Jinyuan 89’,the“elite line tracing and optimization”was developed.The breeding strategy of“variety design and comprehensive technology application”has been verified by breeding practice,which proves that breeding can realize the directionality and efficience of breeding.
