| Sumario: | [EN] The ‘Valencian Tomato’ is one of the traditional varieties of tomato with the most economic projection in current Valencian agriculture. Considering that this variety has not been the subject of genetic improvement, there are more and more problems with the incidence of diseases such as those caused by viruses and fungi in the cultivation fields of the Valencian vegetable orchards. This problem becomes particularly important in the case of soil diseases such as that caused by Fusarium oxysporum f. sp. lycopersici or nematodes of the genus Meloidogyne. Although there are strategies such as biosolarization or the use of rootstocks, in the first case it is laborious and in the second there are no rootstocks developed specifically for the ‘Valencian Tomato’. In this work, based on previously obtained results, a set of 9 hybrids and 8 parents of the same has been tested in a plot where a repeated cultivation of ‘Valencian Tomato’ has occurred with a high incidence of soil fungi and nematodes. This has allowed the selection of 2 very promising hybrids to present high levels of resistance to Fusarium wilt and nematodes |
