تقويم و اصطفاء أنواع و سلالات نخيل التمر المقاومة لمرض البيوض في المغرب

Abstract EN

The date palm trees in Morocco, suffer heavily from Bayoud disease which causes damage to date palm groves.

The resistance of some national and foreign material to this disease was tested in the field and in the laboratory.

Trials carried out in the field showed that «Boukhannee» and other domestic clones were resistant, compared to Iraki and Tuni-sian cultivars which were found susceptible.

Invitro plants obtained from tissue culture in the laboratory were used to test the resistance of clones, less represented in the field, but having higher probability of resistance.
