Figure 1.

Frequency distributions for the traits studied in the 146 recombinant inbred lines of the Dal × Exeter hexaploid oat mapping population. Phenotypes of the parents are marked by arrows.


Figure 2.

A graphical summary of multilocus effects of all quantitative trait locus (QTL) regions affecting total oil and fatty acid (FA) components when (a) the FA components are expressed as a percentage of oil and (b) the total oil and FA contents are expressed as a percentage of seed dry weight. Effects are presented in the order in which FA biosynthesis would occur, and different colored lines are used to connect QTL effects at common loci (identified on the right).


Figure 3.

Quantitative trait locus scans of three linkage groups with parallel effects on oil content and fatty acid components in the Dal × Exeter mapping population and linkage map (D×E) recombinant inbred line population. The mean threshold value of the six scans was used in this figure.
