Deciphering the intrinsic molecular logic of empirical crop breeding from a genomic perspective is a decisive prerequisite for breeding-by-design(BbD),but remains not well ***,we decoded the historical features of past rice breeding by phenotyping and haplotyping 546 accessions covering the majority of cultivars bred in the history of Northeast China(NEC).We revealed that three groups founded the genetic diversities in NEC rice with distinct evolution patterns and traced and verified the breeding footprints to known or genome-wide association study(GWAS)-detected quantitative trait loci(QTLs),or introgressions from indica sub-species with chronological changes in allele *** we summarized a rice breeding trend/principle in NEC,and combined with the successful example in breeding and application of Zhongkefa5 to demonstrate the guiding value of our conclusion for BbD in *** study provides a paradigm for decoding the breeding history of a specific crop to guide BbD,which may have implications in different crop breeding.
