ABSTRACT: In C?te d’Ivoire, ginger (Zingiber officinale Rosc.),
generally used to make a drink called “Gnamankoudji”, has become an important
source of agricultural income diversification. In order to assess the
agromorphological diversity of a ginger collection from different regions of C?te
d’Ivoire, a survey collection of accessions
was carried out in the different production zones of the country. One
hundred and eighty-eight ginger accessions were collected in 15 regions and one autonomous district of C?te
d’Ivoire. Analysis of variance revealed
that all the variables used in this study discriminated between the
ginger accessions collected. Principal component analysis revealed morphological variability of 45.931% for the first two
components. Ascending Hierarchical Classification was used to classify
these accessions into three groups based on
fourteen quantitative characters. These three groups were formed independently of collection areas and are characterized by moderate morphological variability. This variability has been
structured into three distinct agromorphological groups, with thallus
(rhizome) length and width, finger width, secondary finger length and yield in
tons per hectare as distinctive characters. This revealed genetic diversity
could be exploited in ginger breeding and improvement programs in C?te
d’Ivoire.
