Abstract

Nowadays, Tomato spotted wilt virus (TSWV) is one of the most limiting factors for tomato culture in Spain. Some breeding programs have been recently developed to obtain cultivars with resistance to TSWV. The evaluation of six lines of processing tomato obtained from one of these breeding programs and carrying the Sw-5 gene that confers resistance to TSWV, has shown that all these lines have both agronomic (yield, vigor, etc.) and quality characters better or similar to those of control cultivars. The lines tested here could be very useful in regions where TSWV is an endemic disease and to get hybrids that would express heterosis and more stability in different environmental conditions.
