Abstract: Climate change is putting significant pressure on agriculture. The main objective of this study is to identify among the three new cotton varieties that can effectively and sustainably replace the popularized variety IRMA Q302 in the cotton zone of Cameroon. It will be specifically to determine the vegetative behaviour and production characteristics of the new varieties compared to that of the IRMA Q302, compare the ginning of the varieties tested to that of the IRMA Q302. The results of the work show that the vegetative behaviour of the three (03) varieties tested is more excellent IRMA Q302, the production characteristics of IRMA A2262 and IRMA A2188 is higher than IRMA Q302. On ginning characteristics, the results show that the three new varieties have better ginning characteristics than IRMA Q302. In view of these results, have found that the three new varieties tested this involves better than the one popularized despite the significant pressure of climate change. The IRMA A2249 is more suitable in the ecological zone of the Far north and the IRMA A2262 is more suitable for the ecological zone of the North However, in view of the three selection criteria determined by SODECOTON the IRMA A2262 has the potential required to adapt throughout the cotton zone.

Keywords: climate change, performance, assessments, Cameroon cotton zone and new varieties.

RESUME: Les changements climatiques exercent des pressions importantes sur les activités agricoles. La présente étude a pour objectif principal d’identifier parmi les trois nouvelles variétés de coton celle qui pourra remplacer efficacement et de manière durable la variété vulgarisée IRMA Q302 dans la zone cotonnière du Cameroun. Il s’agira spécifiquement de déterminer le comportement végétatif et les caractéristiques de production des nouvelles variétés par rapport à celle de la IRMA Q302, comparer les caractéristiques des variétés testées à celle de la IRMA Q302. Les résultats des travaux révèlent que le comportement végétatif des trois (03) variétés testées sont plus excellente IRMA Q302, les caractéristiques de production de la IRMA A2262 et la IRMA A2188 sont supérieur à la IRMA Q302. Sur les caractéristiques d’égrenage, les résultats démontrent que les trois nouvelles variétés ont des meilleures caractéristiques d’égrenage que la IRMA Q302. Au vu de ces résultats, ont à constater que les trois nouvelles variétés testées ce comporte mieux que celle vulgarisée malgré la pression importante du changement climatique La IRMA A2249 est plus adaptée dans la zone écologique de l’extrême-nord et la IRMA A2262 est plus adaptée pour la zone écologique du nord Cependant, aux vues des trois critères de sélection déterminer par la SODECOTON la IRMA A2262 a le potentielle requis pour s’adapter dans l’ensemble de la zone cotonnière.
