Abstract
C. fusiforme from field-infected members of a highly resistant slash pine [Pinus elliottii var. elliottii] family infected more seedlings of the same parent than did samples of C. fusiforme inocula collected from the general rust population. Greater virulence of inocula from resistant trees is evidence of pathogenic specialization in C. fusiforme.This publication has 0 references indexed in Scilit:
