Résumé

Solenostemon rotundifolius is a species belonging to the Lamiaceae family. It
is currently one of the minor plants of high socio-economic interest. One of
the limitations to promoting this species in Burkina Faso is the lack of varieties that meet consumers’ demands. Implementing a breeding program is an
important step toward achieving this goal. Such a program is based on the variability of agronomical traits of interest within evaluated germplasm. This
study aimed to assess the level of two germplasms variability of S. rotundifolius from Ghana and Burkina Faso for traits related to vegetative development, cycle, and yield. Agromorphological characterization of 174 accessions,
including 116 from Ghana and 58 from Burkina Faso was carried out in
Randomised Complete Block Design with three replications. The characterization was made on the basis of fifteen (15) quantitative traits related to the
canopy and leaf size, the cycle, and the yield. Analysis of variance revealed
significant differences between accessions within each germplasm for all the
evaluated traits. The analysis of the structuration of this agromorphological
variability allowed organizing the accessions into different groups. These results could lead to the identification of accessions within each germplasm for
breeding purposes or future research on genotype-environment interactions.
