Table II. Overview of enzyme activity QTLs identified, overlapping for both 2003 and 2004 harvests, on the basis of individual ILs.

Negative QTLs are colored red and positive QTLs are colored blue. Darker coloration reflects QTLs at P < 0.01, and lighter coloration reflects QTLs at P < 0.05 (in both years with P values derived from t test). Cells labeled with the letter S represent QTLs overlapping with structural genes. Only ILs considered to harbor a QTL or variables that resulted in traits identified are depicted here. Pathway abbreviations are as follows: AAM, amino acid metabolism; GGP, glycolysis/gluconeogenesis; SSM, Suc and starch metabolism; TCA, tricarboxylic acid cycle. All QTLs are defined with reference to ILs that were available for this study. The two QTLs for TPI in IL-1-2 and IL-1-3 and the two QTLs for PPi-PFK in IL-2-4 and IL-2-5 might each be due to a single QTL in the region of overlap between the adjacent ILs.
