Accessions were provided by the National Center for Agricultural Research and Extension (NCARE). Inoculation with the fungus was carried out by using the root dip method. Parameters considered in this study were discoloration, yellowing and fresh weight. Both discoloration and yellowing were measured, recorded according to 1-5 scale and their results ranged from 1-3.5, while fresh weight ranged from 33.1-76.5 g for treatments compared with 41.0-98.8 g for controls. Nine out of 21 studied tomato accessions were significantly different from other accessions and appeared to be resistant to the fungus under experimental conditions according to the 1-5 scale. Most of the resistant accessions were from the slow growing lines, while most of the fast growing accessions were susceptible. The study concluded that resistant accessions are promising ones to be used as root stocks for cultivated tomato varieties.]]>Abu-Blan, H.A.,19953rd Edn.,Al-Ammah, J.D.I.,2011Agrios, G.N.,20055th Edn.,Pages: 922Pages: 922Al-Gazawi, A.A.,19881988Al-Khatib,2004Fusarium oxysporum f. sp.
