| Résumé: | Bayoud disease, caused by Fusarium oxysporum f. sp albedinis, is one of the date palm diseases of the world which is difficult to control. The elite commercial cultivars have shown high susceptibility to the disease. The genetic strategy to use resistant cultivars is the most predominant method, up to now, to control this disease. The diffusion of existing resistant cultivars has been limited due to the mediocre quality of the fruits that do not possess the commercial quality wanted by producers. Research undertaken by INRA on genetic improvement of date palm has permitted the selection of cultivars combining good fruit quality and resistance to bayoud. Studies of the performance of these cultivars have shown that they possess several agro-morphological characters that are more desirable than those of the major common and commercial cultivars in Morocco. Some of these new cultivars have already been multiplied on a large scale by tissue culture and distributed to farmers, not only to rejuvenate palm plantations ravaged by bayoud but also to enhance productivity of traditional low-yielding palm groves. Given their diversity in agronomic characters, the selected cultivars can be of value to other countries contaminated with and threatened by bayoud. Research continues, to identify and multiply other new more effective cultivars. |
