  abstract = {{D}eveloping cultivars with adaptive traits to improve sustainability in the face of climate change is an important option for climate smart agriculture. {T}he {CROPGRO}-cotton model was calibrated and evaluated at two locations in {C}ameroon over a period of two years using two planting dates and four contrasted cultivars. {T}he model was used to assess yield gains by modifying plant traits such as specific leaf area, photosynthetic capacity and crop phenology. {T}he ideotype was tested in conventional and conservation agriculture systems and under baseline and future climate conditions. {T}he results revealed that, compared to existing cultivars, the ideotype requires longer to reach maturity and has thicker leaves with good photosynthetic capacity. {I}n 2050 in {N}orth {C}ameroon, climate change will shorten time to maturity and cause a shift in the rainy season but neither change will have an effect on yields. {S}imulations with an ensemble of climate models revealed that models that assume higher rainfall predicted lower yields, suggesting that {N} leaching is a more important constraint than drought in {N}orth {C}ameroon. {O}ur results will help cotton breeders select promising new traits to introduce in their cultivars for adaptation to climate changes in {C}ameroon and to similar sub-{S}aharan soil, cropping systems and climatic conditions.},
