Title:
Resistance to Pseudomonas syringae pv. tomato in wild Lycopersicon species
Publication date:
1984
Summary:
In 1981, 540 PI accessions and named cultivars of tomato were evaluated for resistance to Pseudomonas syringae pv. tomato, causal agent of bacterial speck of tomato. Resistance was found in Lycopersicon esculentum, L. glandulosum, L. hirsutum, L. peruvianum. and L. pimpinellifolium and in several accessions classified as known or suspected species crosses. Both symptomless reactions and symptoms of an intermediate degree of resistance were observed. The hypersensitive resistance to P. tomato in accessions PI 112215 of L. pimpinellifolium, PI 129157 of L. hirsutum f. glabratum, and L. esculentum 'Ontario 7710' was conditioned by a single dominant gene common to each of the three lines.
