Evaluation of Resistance to TSWV and Agronomic Behaviour of Some TSWV-Resistant Tomato Genotypes in Southern Italy

A two-year research was carried out in Ofanto valley (Basilicata region, southern Italy) in 2006-2007, for evaluating agronomic behaviour of new processing tomato genotypes resistant to tomato spotted wilt virus (TSWV) and ascertaining their effective resistance to the virus. Five TSWV-resistant genotypes (cultivars and lines) were compared in each year the TSWV susceptible cultivar ‘Perfectpeel’ was used as a control. Two transplant dates were adopted in both years: 1) mean-early and 2) mean-late. A split-plot design with 3 reps was followed in the two years. Yield and fruit quality were considered as agronomic traits. About virological aspects, field observations and laboratory analysis (ELISA, IME) were carried out during crop cycles. Phytoplasma infection frequency was also assessed for the same plants. The control cultivar ‘Perfectpeel’ resulted highly productive in both years that were however characterized by low incidence of virus infections; beside, among new genotypes ‘Vespro’ and ‘Suerte’ gave a good yield, while ‘Candia’ and ‘Isi 23259’ exhibited high fruit quality. Virological studies showed that the new processing tomato genotypes were indeed TSWV-resistant. Finally, phytoplasma infections had a dissimilar incidence among plants of the tested genotypes
