Chestnut varieties recommended for cultivation in Extremadura

The selection of plant material (varieties/rootstocks) is crucial for the development of agroforestry systems in chestnut groves; responding to factors such as climate change and the modernization of the crop. It is recommended to use rootstocks resistant to chestnut ink disease and thermal and hydric stress; and varieties suitable for the fresh chestnut market. The CASTANEA operational group has established four experimental plots in Extremadura to evaluate the agronomic performance of varieties and rootstocks. Observations have revealed significant differences between varieties and rootstocks; with Bouche de Betizac and Martainha standing out. It is recommended to consider the type of rootstock when selecting varieties for planting. These plots will serve as references for future recommendations to producers and may drive the development of innovative cultivation techniques.
