The profiles of the log-likelihood ratio test statistics for testing the quantitative trait loci (QTL) affecting free amino acid (FAA) content calculated as a function of genome position on chromosomes 1 (A), 3 (B), 5 (C), 6 (D), 7 (E), 8 (F), and 10 (G). The blue curves are associated with our triploid model, whereas the pink curves with Lander and Botstein’s diploid model. The significance threshold values for the triploid model [indicated by the solid (P = 0.01) and dashed (P = 0.05) horizontal lines] were estimated with 1,000 permutations [Churchill, G. A. & Doerge, D. W. (1994) Genetics 138, 963-971]. According to AIC [Akaike, H. (1994) IEEE Trans. Automatic Control 19, 716-723], all of the QTL detected for FAA content are fit better by the three- rather than two-effect triploid model. Marker names and map distances (in cM) are given below each profile [Wang, X. L., Woo, Y. M., Kim, C. S. & Larkins, B. A. (2001) Plant Physiol. 125, 1271-1282].
