Agriculture of Uruguay can benefit from crop rotation with alternative winter crops such as canola, plant belonguing to the Cruciferae family, for reducing quantitative and qualitative losses in the production of wheat and other grass crops caused by diseases and insect pests as well as benefiting from reduction of input costs associated with their control as observed elsewhere (Tomm, 2005; Tomm et al., 2005; Tomm, 2006). Aiming at making available to farmers of Uruguay the benefits from new canola genotypes that performed well in other South American countries, such as Paraguay and Brazil, led to the beginning of a number of activities to reach this objective. Activities started with training of technical personnel (Fig. 1), and the beginning of experiments to evaluate the performance of genotypes under the growing conditions of Uruguay. These investments along with other efforts likely will lead to the expansion of commercial canola production in Uruguay. The experiment (Fig. 2 and 3) reported here aimed at assessing the comparative adaptation of hybrids in commercial use in Brazil and Paraguay, and newly developed genotypes, to the growing conditions of Uruguay.
