Inheritance of Tolerance to a Pepper Virus in Florida. T. A. Zitter, Assistant Professor, University of Florida, Agricultural Research and Education Center, Belle Glade 33430; A. A. Cook, Professor, Plant Pathology Department, University of Florida, Gainesville 32601. Phytopathology 63:1211-1212. DOI: 10.1094/Phyto-63-1211.

The tolerance of ‘Avelar’, a pepper (Capsicum annuum) cultivar from Brazil, to a disease caused by a virus tentatively designated “pepper mottle virus” was found to result from a single (homozygous) recessive gene. Tolerant plants remained symptomless for ca. 4 weeks after inoculation but later developed a mild mottle on the inoculated and lower systemically infected leaves. Susceptible plants developed severe mottle symptoms within a week. Segregation for susceptibility in test progenies to pepper mottle virus and uniform resistance of similar progenies in earlier studies to tobacco etch and potato Y virus was considered additional evidence that pepper mottle virus is distinct from both of these viruses.
