Abstract:
The aim of this study is evaluating twenty-two tomato hybrids and rootstocks, widely planted in greenhouses in the Syrian coast, for their susceptibility to Fusarium wilt disease caused by the fungus Fusarium oxysporum f. sp. lycopersici. This study conducted in the greenhouse in the Agricultural Research Centre in Lattakia, and in a greenhouse in Alideia in Jableh countryside during the years 2019-2020. The tomato seedlings were artificially inoculated with the spore suspension of the pathogen directly after planting in the pots. Disease intensity and severity were recorded, and the influence of the pathogen on plant productivity of fruits were also estimated after 100 days of inoculation in the trial of planting in highly infected soil. Results showed a big difference among tested cultivars in their susceptibility and disease severity. The high productivity hybrids (Astona, Bastona, Huda, Domna, Sentia, Sedra, Nasma, Jawaher, Ninar, Dalal, Samar, Dalina) were high susceptible to susceptible to the wilt disease, while, the rootstocks (Inpower, Empajador, Befort, Estamino, Bromeno) and the hybrids (Mandalon and Yosra) were high resistant, compared to other tested hybrids and rootstocks, which affect plant productivity, the production of fruit was decreased between (7 and 85)% according to the tomato cultivar.
