n 2011,the Sugarcane Breeding Program of Estación Experimental Agroindustrial Obispo Colombres (Tucumán, R. Argentina) released variety TUC 95-10 commercially. The new cultivar was evaluated in a series of multi-environment trials across different crop ages to assess its productive performance in Tucumán sugarcane area and compare it with LCP 85-384, the principal variety in the province. On account of their flexibility, linear mixed models (LMM) allow the evaluation of the suitability of varieties with a multi-environment and multi-age single model, since they consider the existence of heterogeneous residual variances among different environments and the possible lack of independence among observations, i.e temporal correlations among crop ages and spatial correlation among neighbouring plots. This work aimed to evaluate the productive performance and industrial quality of TUC 95-10 with a multi-environment LMM through different crop ages. The trials were conducted
