Regional differences in distribution of resistance to <i>M. lini</i> in populations of <i>L. marginale.</i>

<p>An average of 30 individual hosts from each of 5 Mountains and 5 Plains populations were challenged with 12 differential <i>M. lini</i> isolates. For each population from Mountains (top panel) and Plains (bottom panel), the number of differential isolates to which individual hosts showed resistance is reported, with 0 meaning the hosts were susceptible to all pathogen isolates and 12 meaning the hosts were resistant to all pathogen isolates tested.
