Fig. 1From: Molecular markers associated with aluminium tolerance in Sorghum bicolorFrequency distribution of NRLAl of 229 F2:3 progeny derived from a cross between Seredo, an aluminium sensitive sorghum line, and ICSR 110, an aluminium tolerant line. The NRLAl mean values for Seredo and ICSR 110 were 3.8 (n = 40) and 6.0 (n = 40), respectively as shown by the arrowsBack to article page
