This study was designed to develop predictions of field breeding values for fusiform rust resistance from early testing under greenhouse conditions. The experiment was conducted at the USDA Forest Service Resistance Screening Center (RSC) near Asheville,N.C. Sis-week-old seedlings from four groups of 25 slash pine families plus six seedlots with different levels of resistance were inoculated with fusiform rust fungus in three different testing periods using the concentrated basidiospore suspension technique. Six months after inoculation, the presence (1) of absence (0) of ten different fusiform rust symptoms, the number of adventitious shoots present in the galled area, and the number of galls per seedling were evaluated. Several other traits were constructedby combining individual traits. Also, traits specifying gall characteristics were evaluated on a single gall and on all galls present on a given seedling. A total of 22 different traits were evaluated. The results indicated that most traits ranked slash pine families consistently across the different testing periods, but trait incidence levels varied from test to test; therefore, to compare families tested in different tests it will be imperative to adjust the fmaily means for the scale effects of the test in which they were tested. Also, transformation of the binomial traits, especially use of logistic transformation, reduced family by test interaction and should be considered as part of the analysis of RSC data on binomial traits.
