Biometric Analysis on Genetic Divergence between Parental and Regenerated Accessions in Tall Coconut Palms (Cocos nucifera L.) from International Genebank for Africa and the Indian Ocean
This
study endeavour assesses agromorphological likeness between initial introductions
and regenerated accessions at the International Coconut Genebank for Africa and
the Indian Ocean (ICG-AIO) based in C?te d’Ivoire. Ten couples of
parental (G0) and regenerated (G1) accessions of Tall coconut palms were
analyzed using Principal Component Analysis (PCA) and Multiple Analysis of
Variance (MANOVA) from 26 agromorphological characters. The main results showed
a relative decrease in the expression of the phenotypical traits concerning the component of
the fruit, height and vigor of the stem and yield of bunches and fruits after
one regeneration cycle. But, a high
proportion (69%) of studied characters from leaf, inflorescence and nut
components showed likeness between G0 and G1 accessions. After one regeneration
cycle, the controlled pollination method guarantees significant conservation of the
expression of the majority of agromorphological traits. Consequently,
regenerated accessions of Tall coconut palms can be used to pursue research and
development programs in C?te d’Ivoire.
