Structuring of the ginger (Zingiber officinale Roscoe.) cultivation system in Côte d'Ivoire and assessment of the morphological variability of rhizomes

Agromorphological Characterization of Ginger (<i>Zingiber officinale</i> Rosc., Zingiberaceae) Accessions Grown in Côte d’Ivoire

“…The presence of duplicates within the pool could be explained by the method used to obtain planting material. In fact, most growers obtain planting material for their plots either by purchase on local markets or by donation [15]. The same genetic structuring was observed in Benin, where ginger accessions were grouped into three groups independently of their collection area on the basis of characters such as rhizome length, width, thickness and weight, skin and flesh color, finger length, streak arrangement and fiber density for 29 ginger accessions [18].…”

“…This species is therefore an important source of agricultural income diversification and the raw material for a category of food industries. In addition, the essential oils extracted supply an important export network between Côte d'Ivoire and Europe [15]. Despite its importance as a food, therapeutic and industrial crop, and despite the fact that it occupies an important place in people's socio-economic activities, ginger cultivation faces a number of factors that limit its development.…”

“…Numerous genetic diversity studies have been conducted for ginger management and breeding [16] [17] [18]. However, in Côte d'Ivoire, apart from the work on the genetic diversity of ginger carried out by [15], no study has yet been carried out on the distribution and agronomic characterization of this plant. Therefore, analysis of the genetic diversity of ginger based on agronomic traits is essential for understanding its performance and designing breeding programs [17].…”
