| Abstract:
In the study reactions of 31 tomato cultivars, 3 rootstock and some wild Lycopersicon (L. peruvianum var. humifusum, L. peruvianum f. glandulosum, L. hirsutum, L. pimpinellifolium, L. esculentum var. cerasiforme, L. chilense) species to tomato pith necrosis caused by Pseudomonas corrugata, Pseudomonas viridiflava, Pseudomonas cichori and Erwinia carotovora subsp. carotovora were determined. The plants grown in pots in greenhouse were artificially inoculated. Severity of the disease was assessed one month after inoculation. None of the cultivars tested were resistant to the strains except cultivars ACE 55 VF and Nun 2048 found resistant to E. carotovora subsp carotovora. In L. peruvianum f. glandulosum and L. peruvianum var humifusum resistance to the strains were determined. | |
