Researchers in Spain are working to extend avocado cultivation throughout the year by introducing new varieties with different textures and flavors. Currently, avocado cultivation in Spain is limited to certain periods due to importation of fruits during the off-season. The 'La Mayora' Institute is advocating for the cultivation of four to five varieties to increase domestic production and reduce reliance on imports. Spain is the leading European producer of avocados, with the majority of production concentrated in Malaga and Granada.
