Analysis of the Genetic Diversity within Ten Citrus Species in Burkina Faso

Citrus fruits are plant species that grow in tropical and subtropical zones, particularly in Burkina Faso. The aim of this study is to characterize citrus species in Burkina Faso. To this end, 10 citrus species were evaluated in a Fisher block with two replications. The IPGRI citrus descriptor was used to select the variables to be measured. The morphological evaluation concerned the leaves and fruits of the 10 citrus species. The results show very remarkable variations, especially in incisions on the edge of the leaf blade, the shape of the top of the leaf blade, the shape of the leaf blade and the presence of wings on the petiole. As for the fruits of citrus species, variations in shape and flesh are observed. Qualitatively, the fruits are recognizable by their shape and by the presence or absence of a neck, a depression at the distal end and an outgrowth. The results of the data analysis of the quantitative fruit variables showed that there was a very highly significant difference at the 5% threshold. In view of the results obtained, it is necessary to study the variability within each citrus species.
