Caracterización de razas cubanas de maíz (Zea mays l.) Mediante marcadores agromorfológicos en la colección nacional del cultivo

Cuban maize (Zea mays L.) races constitute a potential of high genetic value for Cuba and the Caribbean region. This work was aimed at characterizing Cuban races by means of agro-morphological markers in the national crop collection. Thus, 92 accessions from INIFAT´s gene bank were planted; four com...
