Influence de la provenance du géniteur et du type de pollen sur la fructification sous pollinisation contrôlée chez <em>Dacryodes edulis</em> (Burseraceae) au Cameroun

Abstract: Très peu de travaux ont été réalisés sur l'amélioration variétale des espèces locales. L'amélioration de leur germoplasme aboutit à l'obtention du matériel végétal amélioré destiné à la création de nouveaux cultivars. Des essais de pollinisations croisées contrôlées ont été menés sur Dacryodes edulis dans le but d'évaluer l'influence de la provenance des géniteurs et du type de pollen sur la fructification de 14 accessions femelles issues de 03 provenances. Les croisements ont été effectués selon un schéma en … Show more

“…After the initial phases of clonal selection, the opportunity will arise for controlled pollinations between proven elite clones as has been done in Ziziphus mauritiana in the Sahel and Dacryodes edulis in Cameroon (Makueti et al, 2012). In this way, it should be possible to take advantage of specific-combining ability in unrelated superior clones and to produce progeny with heterosis in desirable traits that exceed what is found in the wild populations.…”
