Abstract

Accessions of wild Lycopersicon germplasm were screened for resistance to Pseudomonas syringae pv tomato (P.s. tomato). Resistance to both race-0 and race-1 strains of P.s. tomato was identified in L. pimpinellifolium, L. peruvianum and L. hirsutum var. glabratum. Resistance to race-0 derived from L. hirsutum var. glabratum (Pto3) appeared to be inherited independently of Pto1 and Pto2. Filial and backcross generations derived from interspecific crosses between L. esculentum and L. hirsutum var. glabratum revealed that Pto3 resistance was inherited in a complex fashion and was incompletely dominant under conditions of high bacteria inocula. Resistance to P.s. tomato race-1 (Pto4) was also identified in L. hirsutum var. glabratum. Pto3 and Pto4 segregated independently of each other.
