摘要

Solenostemon rotundifolius [(Poir.) J. K. Morton] (Lamiaceae) is commonly called Fabirama, Frafra potato or Innala. It is a tuber crop cultivated in many countries in Africa and Asia. Its tubers contain significant rate of carbohydrates, proteins, fibers, vitamins and antioxidants. Besides its nutritional attributes, S. rotundifolius has also strong agronomic and economic potentialities and could be financially rewarding to the farm economy. However, S. rotundifolius is currently a minor crop in African agro ecosystem. It is a priority to contribute to a better preservation and a sustainable use of its genetic resources. Understanding morphological variability is a key step for S. rotundifolius genetic resources management. Previous studies identified three morphotypes based on tuber skin color but a complete description of these morphotypes is not yet done. This study is a contribution to a better description of the main morphotypes of S. rotundifolius cultivated in Burkina Faso. Three accessions representing three morphotypes were described based on twenty five qualitative morphological traits assessed at different stages of plant growth. Significant variability between the morphotypes was observed for young plant color, leaves morphology, color and form of inflorescence as well as tuber skin and flesh color. This work provided useful tools for the characterization of S. rotundifolius genetic resources.

Morton]（唇形科）通常被称为Fabirama，Frafra马铃薯或Innala。它是非洲和亚洲许多国家/地区种植的块茎作物。其块茎中含有大量的碳水化合物，蛋白质，纤维，维生素和抗氧化剂。除了营养成分外，圆形葡萄球菌还具有很强的农艺和经济潜力，并可能在经济上对农业经济有所回报。但是，圆形非洲链球菌目前是非洲农业生态系统中的次要作物。为更好地保存和可持续利用其遗传资源做出贡献是当务之急。了解形态变异性是S. rotundifolius遗传资源管理的关键步骤。先前的研究根据块茎皮肤的颜色确定了三种形态，但是尚未对这些形态进行完整的描述。这项研究有助于更好地描述布基纳法索栽培的圆形葡萄球菌的主要形态型。基于在植物生长的不同阶段评估的二十五个定性形态特征，描述了代表三种形态型的三个种质。对于幼小的植物颜色，叶片形态，花序的颜色和形式以及块茎皮肤和果肉的颜色，观察到形态型之间的显着差异。这项工作提供了有用的工具，用于表征圆形葡萄球菌的遗传资源。
