Fig. 1: Replication of shoot dry weight and rhizosphere mass QTLs from previous studies.

a QTLs identified for SDW on chromosome 9 position 63.63719184 and chromosome 2 position 42.7291229, coinciding with a QTL identified previously (chromosome 9 position 62.897108) by Khan et al 2012. b QTL of RM on chromosome 5 position 62.00574891, and chromosome 9 position 62.71397636, which coincide with root trait QTLs previously identified for lateral root number chromosome 5 position 53.4–86.1, and several on chromosome 9, including fresh and dry shoot weight, (chromosome 9 position 81.3–95.3), lateral root density per branched zone (chromosome 9 position 33.8–88.7), and total root size (chromosome 9 position 39.4–75.1) from Khan et al 2021. c Scatter plots showing the distribution of SDW measurements on chromosome 2 position 42.7291229 and chromosome 9 position 63.63719184 for both modern (AA) and wild (BB) alleles. For the QTL on Chromosome 2, n = 76 and 112 biologically independent samples for AA and BB respectively. For the QTL on Chromosome 9, n = 106 and 82 biologically independent samples for AA and BB respectively. In addition to the scatter plot, data are presented as mean values +/− two times the SEM. d Significant additivity of alleles for SDW (p < 0.05); n of 42, 80, and 70 for biologically independent plants containing neither allele (AA/BB), either BB allele on chromosome 2, or AA on chromosome 9 (AA/AA or BB/BB), or both AA and BB alleles (BB/AA) respectively. In addition to the scatter plot, data are presented with boxplots representing the median value, the interquartile range, and whiskers representing the minimal and maximal values excluding points greater than 1.5 times the interquartile range. e Scatter plots showing the distribution of RM measurements on chromosome 5 (pos 62.00574891), and chromosome 9 (pos 62.71397636) for both modern (AA) and wild (BB) alleles. For the QTL on Chromosome 5, n = 92 and 98 biologically independent samples for AA and BB respectively. For the QTL on Chromosome 9, n = 92 and 98 biologically independent samples for AA and BB respectively. In addition to the scatter plot, data are presented as mean values +/− two times the SEM. f No additivity of alleles was observed for RM. In addition to the scatter plot, data are presented with boxplots representing the median value, the interquartile range, and whiskers representing the minimal and maximal values excluding points greater than 1.5 times the interquartile range.
