Abbreviations: IL, introgression line; QTL, quantitative trait loci; N, negative; P, positive.

Limits denote the maximum possible QTL region. For the sequential and IL mapping, the limits defined by those analyses and the ILs tested are given. Other traits mapping to these regions are also noted. QTLs defined only by sequential IL mapping are shown in bold.
