Percentage of infection by Cronartium quercuum f. sp. fusiforme on seedlings of seven half-sib families of loblolly pine (Pinus taeda) following artificial inoculation were compared with those of the same families after 5 yr in a high-hazard rust area. Family ranking based on percentage of seedlings galled were essentially the same, demonstrating the reliability of artificial inoculation as a means of evaluating rust resistance in loblolly pine.
