Six genotypes (TxAG-3, PI 341885, Toalson, Starr, Florunner, and Goldin 1) were evaluated for reaction to Pythium myriotylum Drechs, and Rhizoctonia solani Kuhn in the greenhouse to: 1) confirm field results as to the relative disease reactions of the entries; 2) ascertain whether peg versus pod exposure to pathogens confounds selection for pod rot resistance; 3) examine the utility of greenhouse inoculation in screening for pod rot resistance; and 4) evaluate simultaneous screening of plants for reaction to these fungi. Adult plants were exposed at two stages of fruit development. TxAG-3 had significantly less pod decay from each organism singly and in combination at both times of exposure to the pathogens than did the other entries. Exposure to the pathogens at the pegging and pod-filling stages of development produced similar results.
