These diseases are increasingly widespread where cultivation is carried out intensively, with short rotation shifts and following the excessive proliferation of so-called &#8220;vector&#8221; insects. <\/p>\n<p>To prevent viral infections and as the chemical fight against insects is not always decisive, the use of genetically induced resistance therefore appears to be the most effective, as well as the most ecological, means. Still with regard to pathogenic viruses, the one currently most feared and widespread in the main cultivation areas of the Mediterranean is the TSWV or spotted wilt virus, whose generation inside the tomato plant is favored by the lesions practiced by a tyramopteran insect called thrips . All the main F.1 hybrids of processing tomatoes proposed by ESASEM in risk areas are resistant or highly tolerant towards this virus, being provided with a dominant gene, with a broad spectrum of action, signed as SW-5. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-363794132\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-363794132\" data-tab-index=\"2\" style=\"--n-tabs-title-order: 2;\" class=\" elementor-element elementor-element-6f4b56e e-con-full e-flex e-con e-child\" data-id=\"6f4b56e\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-298f360 elementor-widget elementor-widget-text-editor\" data-id=\"298f360\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>There are numerous types of FRESH CONSUMPTION TOMATOES that the research deals with, starting from salad food&#8221; of large size and for single fruit harvesting, up to the &#8220;cherry and datterino&#8221;, to be harvested in whole bunches, with &#8220;mignon&#8221; fruits with a crunchy and tasty pulp. Contrary to the industrial tomato, which shows a limited typological differentiation, but which is strongly characterized by the technological requisites it must possess in relation to the type of industrial transformation for which it is intended, the so-called table tomato, has very logical characteristics and much more variable production attitudes, in relation to the demands of the consumer markets, seasonality and the cultivation environment (think of the greenhouse).<\/p>\n<p>ESASEM &#8220;Breeders&#8221; conduct intense research programs to build well-characterized F.1 hybrids, then having them pass through severe selective tests conducted at the company headquarters, but also in the most typical cultivation areas, in Italy and abroad.<\/p>\n<p>Even the fresh market tomato must be protected against disease. The &#8220;greenhouse&#8221; environment favors the proliferation of parasitic insects and the development of dangerous masses of inoculum, fungal, bacterial and viral. ESASEM researchers work to associate the genotypes in the selection phase with genes for resistance against tracheomycosis and Fusarium roots lycopersici in particular, cladosporiosis, nematodes and some of the most harmful viruses, such as ToMV, TYLCV and TSWV, a virus which is also widespread in the open field on processing tomatoes.<\/p>\n<p>Thanks also to the collaboration with leading Italian and foreign university institutes, the onset of diseases is monitored with phytopathological techniques such as the DAS-ELISA; the resistance genes are prepared and then inserted into the &#8220;inbred&#8221; lines with crossing, back-crossing and individual selection, the acquired resistance is finally confirmed with the use of innovative molecular methodologies and with the use of markers molecular.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-363794133\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-363794133\" data-tab-index=\"3\" style=\"--n-tabs-title-order: 3;\" class=\" elementor-element elementor-element-1ac23c7 e-con-full e-flex e-con e-child\" data-id=\"1ac23c7\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-750b2f5 elementor-widget elementor-widget-text-editor\" data-id=\"750b2f5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The PEPERONE is a species widely cultivated in various parts of Italy.
