From: Molecular markers associated with aluminium tolerance in Sorghum bicolor
Net root length of sorghum F2:3 progeny grown in the presence of 148 μM aluminium based on the different genotypic classes for four dominant markers (811_1400, 835_200, CTG29_3b and 884_200). For each locus, genotypes with different letters indicated on top of the bars were significantly different from each other in their tolerance to Al toxicity. The error bars represent standard error values
