ABSTRACT: Cassava is the second most important food crop
produced and consumed in Côte d’Ivoire, after yam. White-fleshed
varieties, which are low in total carotenoids, are widespread, while coloured-fleshed
varieties (yellow to orange), carotenoid-rich, are rare. However, the
consumption of carotenoid-rich cassava varieties could help to alleviate health
problems related to vitamin A deficiency. This study aims to identify high
agronomic performance, carotenoid-rich and versatile cassava varieties among 31
clones introduced from IITA. They were compared to three controls, Bocou2, Yacé
and Bonou2, according to agronomic and technological parameters. Results found
that out of the 31 clones, six (I082425, I084157, I084563, I085894, I083774 and
I070520) were more productive than the
control Bocou2 (46.01 ± 14.88 t·ha-1); the clone
I083774 had the highest yield (55.88 ± 6.16 t·ha-1).
Twenty-one clones had dry matter contents, ranging from 37% to 41%,
significantly similar to Yacé control (42.70%). Thirteen clones had highest
total carotenoid contents than the control Bocou2. Clones I084157 and I082425
recorded the highest total carotenoid contents with 17.57 ± 1.92 and 18.39 ± 1.19 μg·g-1 respectively. Overall 31 tested clones were
fibrous to varying degrees while 27 clones had mild or neutral post-cooking
flavours and 17 clones had poor cooking. The clone I084157 is the best
compromise of agronomic and technological desired traits.
