Phaseolus lunatus is a legume rich in protein and essential amino acids, with a notable morphological diversity that influences its floral phenology. The aim of this study was to evaluate the flowering period of four morphotypes and to determine the duration of flower opening. The experiments were carried out at the Université Jean Lorougnon Guédé in Daloa, Côte d’Ivoire. The experimental set-up used was a complete block with 10 plants per morphotype. The results revealed significant variability between morphotypes. Morphotype 3 showed early flowering (79 days), while morphotype 2 was the latest (137 days). Analysis of floral morphology using an optical microscope revealed significant differences between morphotypes in terms of the number of flowers opened and aborted. This study underlines the importance of understanding floral phenology for optimizing P. lunatus production and guiding varietal selection. The variability observed highlights the potential for genetic improvement, in order to develop better-performing varieties that are better adapted to changing climatic conditions.

Abstract: (french)
Phaseolus lunatus est une légumineuse riche en protéines et en acides aminés essentiels, présentant une diversité morphologique notable qui influence sa phénologie florale. Cette étude a pour objectif d’évaluer la période de floraison de quatre morphotypes et de déterminer la durée d’ouverture des fleurs. Les expérimentations ont été menées à l’Université Jean Lorougnon Guédé de Daloa, en Côte d’Ivoire. Le dispositif expérimental utilisé est un block complet avec 10 plants par morphotype. Les résultats ont révélé une variabilité significative entre les morphotypes. Le morphotype 3 a montré une floraison précoce (79 jours), tandis que le morphotype 2 a été le plus tardif (137 jours). L’analyse de la morphologie florale, réalisée à l’aide d’un microscope optique, a mis en évidence des différences significatives entre les morphotypes en ce qui concerne le nombre de fleurs épanouies et avortées. Cette étude souligne l’importance de la compréhension de la phénologie florale pour l’optimisation de la production de P. lunatus et pour orienter la sélection variétale. La variabilité observée met en lumière un potentiel d’amélioration génétique, afin de développer des variétés plus performantes et mieux adaptées aux conditions climatiques changeantes.
