Distribution of B concentrations in tolerant and intolerant M.t. lines after 3 weeks of excess B. The amount of B was quantified in leaves of tolerant and intolerant F₂ lines of both populations and the two tolerant parental lines Paraggio and Caliph and the intolerant parent tap. ICP data were generated on 35–40 F₂ lines of the tolerant and intolerant subsets of both populations, 4–8 repeats of leaf and 4 repeats of root samples for each parent.
