Intensity of take-all for Triticum genotypes in the field trials from harvest years 2008–2011. In panel (a) the bar legend applicable to all four years is given. (a) The 2008 field trial. In 2008 there were five replicates per genotype, except for 10 replicates of the T. monococcum accessions MDR037, MDR046 and MDR229. Bar shows the SED for comparisons between genotypes sown in 5 replicates (SED min.rep = 9.88, max-min = 8.56, max.rep = 6.99, d.f. = 143, P < 0.001). (b) The 2009 field trial, (c) the 2010 field trial and (d) the 2011 field trial. Bars in (b), (c) and (d) show the SEDs for comparisons between genotypes in those year (2009, d.f. = 84, P < 0.001; 2010, d.f. = 124, P < 0.001; 2011, d.f. = 104, P < 0.05).
