Control of Fusarium Crown and Root Rot of Tomato, Caused by Fusarium oxysporum f. sp. radicis-lycopersici , by Grafting onto Resistant Rootstocks

摘要

In this study, the efficacy of grafting two tomato cultivars onto two rootstocks was examined in growth chamber and in greenhouse conditions. The rootstock cultivars Beaufort F₁ and He-Man F₁, already known and confirmed as resistant to Fusarium oxysporum f. sp. radicis-lycopersici , were evaluated during two crop seasons under greenhouse heated with geothermal water in South Tunisia. The cv. Durintha F₁ showed the best plant growth, fruit yield and fruit quality when grafted onto Beaufort F₁; while cv. Bochra F₁ gave the best results when grafted onto He-Man F₁. This study demonstrated that grafting tomato cultivars onto Fusarium resistant rootstocks is one of the best alternatives for controlling Fusarium crown and root rot of tomato.
