Resistance Terminology
HR = High resistance: plant varieties that highly restrict the growth and development of the specified pest or pathogen under normal pest or pathogen pressure when compared to susceptible varieties. These plant varieties may, however, exhibit some symptoms or damage under heavy pathogen or pest pressure.
IR = Intermediate resistance: plant varieties that restrict the growth and development of the specified pest or pathogen, but may exhibit a greater range of symptoms or damage compared to “highly resistant” varieties. Intermediately resistant plant varieties will still show less severe symptoms or damage than susceptible plant varieties when grown under similar environmental conditions and/or pathogen or pest pressure.
T = Tolerance: The ability of a plant variety to endure abiotic stress without serious consequences for growth, appearance and yield.
*Tm: 0 – designates resistance to Pepper Tobamovirus Group 0: BPMoV, TMV: 0, and ToMV: 0
Tm: 0, 1 – designates resistance to Pepper Tobamovirus Group 0 and Group 1: TMGMV & PaMMV
Tm: 0-2 – designates resistance to Pepper Tobamovirus Group 0, 1 and Group 2: PMMoV: 1.2
Tm: 0-3 – designates resistance to Pepper Tobamovirus Group 0, 1, 2 and Group 3: PMMoV: 1.2.3
