“…La tendance de la production sucrière à la hausse amorcée depuis la campagne sucrière 2008/09 en passant de 90 300 t jusqu'à près de 100 000 t en 2010/11, semble être en grande partie liée au développement de variétés plus productives en sucre que sont SP71-1406, SP70-1006, SP70-1143, SP71-8210, SP70-1423 et R579. Ce changement de profil variétal en cours s'est opéré progressivement, d'année en année, au détriment des principaux clones d'alors (Co957 et NCo376) et de bien d'autres plus faiblement représentées telles que Q75, Co440, FR8069, M31/45, R570 et R70/367 (Péné et al, 2012b, Zadi et al, 2017. La sélection variétale apparaît donc comme une composante essentielle dans l'accroissement de la productivité agricole au même titre que l'irrigation dans le contexte des périmètres sucrier de Ferké (Péné et Déa, 2000 ;Péné et al, 2001).…”

“…Malgré cette amélioration substantielle, la production nationale de sucre reste encore déficitaire avec environ 200 mille t/an pour un besoin de consommation estimé à 240 mille t/an (Zadi et al, 2017). Le foreur de tiges Eldana saccharina et deux maladies endémiques économiquement importantes, en l'occurrence le charbon et l'échaudure foliaire causés respectivement par Ustilago scitaminea et Xanthomonas albilieans, constituent les principales contraintes biotiques dans les périmètres sucriers ivoiriens (Kouamé et al, 2010, Zadi et al, 2017. Ces contraintes biotiques comptent de plus en plus parmi les facteurs limitants de la productivité agricole avec une perte de rendements en cannes et en sucre pouvant atteindre parfois 20 voire 30 % due notamment au foreur de tiges (Péné et al, 2016).…”

Genetic Diversity of First Sugarcane Varieties of Reunion-Ivorian Origin Preselected in Ferké, Ivory Coast Objectives: The overall study objective was to contribute to sugarcane yield improvement in Ivory Coast. It aimed to characterize the genetic diversity of the first batch of 148 sugar cane varieties of Reunion-Ivorian origin preselected at the "one-row" stage for standard selection trials of 1st and 2nd stages to be carried out under Ferké commercial field conditions. Methodology and results: It was conducted on Ferké 2 experimental station under full sprinkler irrigation in northern Ivory Coast. These varieties were pre-selected in 1st regrowth among 985 clones planted per family, one individual per row 3 m long without repetition and compared to a control variety (SP70-1006).That one was replicated several times every 5 rows to ease agronomics observations of clones in comparison with the control. Quantitative as well as qualitative traits observed at the age of 10 months were subjected to a series of multivariate analyses. The study showed that quantitative traits, which better explained diversity of varieties, were the following in decreasing order: flowering rate, number of millable stalks/3m, stalk diameter, and stalk height. Those phenotypic traits highly contributed to discrimination of varieties into 8 clusters, which suggested a good genetic diversity among all 148 preselected clones. Four best-represented clusters (63.5 % of total) comprised 20-30 individuals each, whereas less represented clusters (36.5 %) involved 11-15 individuals each. Conclusion and application of results: Quantitative traits most relevant in variety clustering were high tillering, moderate tillering, erect traits, which were associated respectively with clusters G1, G7 and G2. As for lodging traits, they were associated with 6 clusters all together, namely G2, G3, G4, G5, G6 and G8. The genetic variability so shown is a prerequisite for further selections trials under commercial field conditions.

“…As far as Ferké sugarcane plantations in Ivory Coast were concerned, development of high sugar yielding varieties (9-10 t/ha) contributed significantly to improvement of crop productivity by 25 % from 2010-11 to 2014-15 [3]. Despite that progress in yield, the Ivorian sugar production is still in deficit, with about 200 000 t/yr over a total sugar consumption estimated to 240 000 t/yr [4]. Stem borer (Eldana saccharina W) and two endemic diseases economically important, i.e.…”

Aims:The overall study objective was to contribute to sugarcane yield improvement in Ivory Coast. Specific objective was to evaluate the genetic diversity of Reunion-Ivorian first sugarcane genotypes preselected at one-row stage for further advanced selection trials of 1 st and 2 nd steps to be carried out under Ferké commercial field conditions. Study Design: It was conducted on Ferké 2 experimental station under full covering sprinkler irrigation in northern Ivory Coast. The genotypes were preselected in 1 st ratoon among 985 clones planted in single rows of 3 m per clone with 1.5 m of row-spacing following families. Genotypes were not replicated except for the control variety SP70/1006. That one was replicated several times every 5 rows to ease agronomics observations of clones in comparison with the control. Quantitative as well as qualitative traits observed at the age of 10 months were subjected to a series of multivariate analyses.
