Phenotypic distribution of percent loose smut incidence (LSI, %) for the Strongfield/Blackbird DH mapping population in response to <i>Ustilago tritici</i> individual races T26, T32 and T33.

<p>Percent loose smut incidence levels for parents Blackbird and Strongfield are indicated by ‘B’ and ‘S’, respectively.</p

A QTL for loose smut resistance detected on chromosome 6B.

<p>A region of the chromosome 6B genetic map showing the position of SNP and SSR markers and highly significant QTL (<i>QUt</i>.<i>spa-6B</i>.<i>2</i>) associated with resistance to multiple races (T26, T32 and T33) of <i>Ustilago tritici</i>. Markers associated with the QTL are shown in green to the left of the double line representing the chromosome and their positions along the map are given to the right. A thick and multi-colored vertical line below the QTL peaks represents the genome-wide LOD threshold values (range 3.28–3.55) for declaring significant QTL.</p

Phenotypic distribution of percent loose smut incidence (LSI, %) for the Strongfield/Blackbird DH mapping population in response to a mixture of <i>Ustilago tritici</i> races T26, T32 and T33.

<p>Percent loose smut incidence levels for parents ‘Blackbird’ and ‘Strongfield’ are indicated by ‘B’ and ‘S’, respectively. H1 represents head 1 and H2 represents head 2.</p
