Assessment of genetic variability in resistance to brown spot needle disease in longleaf pine: Analysis of performance in test crosses

As a means to facilitate early screening of seedlings for susceptibility to this blight disease, artificial inoculation methods have been introduced for use in greenhouse environments (Kais 1975). If shown to produce resistance readings that correspond well with field observations, this methodology will be an indispensable aid to selecting families and possibly individual trees with improved resistance. In this report, we present preliminary findings from research designed to obtain additional information about genetic variation in resistance to this disease.
