Abstract

Genetic relationships among 18 regenerated tall coconut accessions from International Coconut Genebank for Africa and Indian Ocean (ICG-AIO) located at Côte d’Ivoire were studied. Analyses were achieved from 17 quantitative characters of the reliable minimal list of agro-morphological descriptors for coconut proposed by Coconut Genetic Resources Network (COGENT) in 2007. From achieved Multivariate Analyses (MVA) two geographical clusters including Afro-Indian and Far East were observed in the first generation of regenerated tall coconut accessions. In addition regenerated tall coconut accessions whose parents come from South Pacific geographical area were the more varied. This typology is similar to the one of the initial introductions previously established. Thus, creation of improved hybrids from heterosis effect searching a long time exploited in tall coconut accessions can always be pursued with regenerated accessions in Côte d’Ivoire coconut program.

Key words: Tall regenerated accessions, minimum list of coconut descriptors, morphological typology, multivariate analyses (MVA), Côte d’Ivoire.
