Fig. 6. 3,4 Dihydroxyphenylalanine (L-DOPA) values obtained from chromosome substitution lines of Langdon durum and Chinese Spring. Three replicates of three seeds each from each of the substitution lines indicated were incubated for 2 h in 1.5 mL of 10 mM L-DOPA in 50 mM 3-(N-morpholino) propane sulfonic acid (MOPS) (pH 6.5). Solid bars are Chinese Spring D-genome for A-genome substitutions, open bars are Chinese Spring D-genome for B-genome substitutions. Error bars represent one SD above the mean.
