Mapping results of qRDWN6XB on chromosome 6. (a) The genetic linkage map of the qRDWN6XB based on 75 CSSLs. (b, c) the high resolution linkage map of the qRDWN6XB region generated using BC5F2:3 population; the allele was mapped to the region between markers RM19766 and RM19776. (d) Genotypes and phenotypes of the parental lines (CSSL45 and ZH9308) and the homozygous recombinants plants for fine mapping. The white and black bars denote the marker genotype of ZH9308 and CSSL45, respectively. Root dry weight (RDW), root length (RL) and root number (RN) are presented as means ± SD
