Stall, former Research Assistant Department of Vegetable Crops, University of Florida, Present address of junior author: Ext. County Agent in Vegetables, 18710 SW 288 St., Homestead, Florida 33030. Phytopathology 64:1290-1293. Accepted for publication 7 May 1974. DOI: 10.1094/Phyto-64-1290.

Fruit from different pepper lines were not equally susceptible to Erwinia carotovora. Only 3% of the fruit of the most tolerant cultivar, Jalapeno, had lesions 2 days after inoculation, whereas 75% of the fruit of the most susceptible cultivar tested had lesions. All inoculations were made by wounding the fruit with straight pins that had been dipped in a suspension of E. carotovora. Tolerance was inherited, as indicated by assays of progenies from two test crosses, and was controlled by a relatively few genes, or a few groups of linked genes.
