Analysis of a five-parent diallel in a greenhouse estimated general and specific combining ability (GCA and SCA) effects for resistance of Japanese plum (Prunus salicina Lindl. and hybrids) to Xanthomonas campestris pv. pruni (Smith) Dye stem canker, as measured by length of inoculated cankers, canker appearance rating, and canker expansion rate. `Friar' and `Gulfruby' were the most susceptible parents. `Burbank', `Wilson', and' Wade' had similar GCA values for length of inoculated cankers, but' Wade' was the superior parent in transmitting canker resistance, as measured by canker appearance rating. SCA was not important in determining the performance of a cross. Canker appearance rating was the best measure of resistance in the greenhouse tests and provided a greater separation of GCA estimates and lower coefficient of variation.
