In Côte d'Ivoire, cashew cultivation faces several health obstacles. Among these problems, bacteriosis causes extensive damage to twigs, leaves and fruits, lowers the quality of crops and causes yield losses. The spread of this disease would be under the determination of the morphological characters of the cashew tree. The objective of this study is to search for agro-morphological determinants that influence the spread of bacteriosis in agroforestry systems in Côte d'Ivoire. To achieve this objective, 30 cashew trees spread across 26 agroforestry cashew orchards in the Korhogo, Sinématiali and Boundiali departments were chosen and geolocated. The study factor is the clone, consisting of 30 cashew genotypes, with 13 modalities. The collected data was subjected to descriptive analysis, correlation test, ACP and ascending hierarchical classification (CAH). The results obtained showed that the size and leaf areas and size of cashew trees are determinants that promote the spread of bacteriosis in these 30 cashew genotypes. Following this result, the ascending hierarchical classification (CAH) made it possible to screen the genotypes into three groups. These results should contribute to the agroecological management of bacteriosis, to enhance and intensify agroforestry cropping systems in Côte d'Ivoire.
