From: Genomic insight into balancing high yield, good quality, and blast resistance of japonica rice
Rice genomic distribution and linkage drag for yield, taste quality, and blast resistance associated genes. a Allelic frequency of superior alleles related to yield, taste quality, and blast resistance in BSLVs, BRMVs, and BSMVs. b Genomic linkage disequilibrium blocks drawn through genome-wide SNPs with a 15-kb sliding window size advantage, and the genomic locations of the 158 genes related to yield, rice quality, and resistance are illustrated along the 12 rice chromosomes. The functional category of each gene is indicated by colored lines pointing at the gene labels. Each chromosome in the segments represents a genetic drag with R2 > 0.95. Linked genes on chromosomes marked with red dashed boxes. c Schematic diagram of the genetic linkage among yield, good taste, and blast resistance genes on chromosome 6. Hap1 represents a high yield and excellent taste linkage type, mainly distributed in the BSLV. Hap2 represents low-yield and blast-resistant linkage types, mainly distributed in BRMV, and Hap3 represents the high-yield and blast susceptible linkage type, mainly distributed in the BSRM. The distribution of the above three linkage types in varieties in different breeding years is indicated by light red circles with various numbers. Linked genes are denoted by red dashed boxes. BSLVs; blast-sensitive and low-amylose (8–12%) varieties; BRMVs; blast-resistant and medium-amylose (13–18%) varieties
