Popis: SUMMARY The terms cultivar or variety used with genetically improved plants that come from species is generally controversial. These terms are being used indiscriminately in written and oral communication. The objective of this paper is to provide information about the proper use of this agricultural terminology. The term variety created by Linneaus in 1751, continues unchanged, and defines a plant that has been modified through accidental environmental alterations. Permanent morphological and physiological characters are what distinguish the variety. Taxonomically, variety occurs between specie and cultivar. When sugar cane crops began to be cultivated, Black Cheribon, Criolla, Cristalina, Badila, Uba, Chunnee, etc., varieties were the basis for the industry. Nevertheless, when problems arose that affected production, they were replaced with genetically improved cultivars. The varieties presently exist only in germplasm gardens. The term cultivar is an artificial neologism that originated in english, through the agglutination of parts of the expression cultivated variety (culti-var). The error in agricultural terminology occurred when cultivars were called varieties. This caused communication problems, mainly at the international level, with regards to the International Code of Nomenclature for Cultivated Plants which defines cultivated plants that have been genetically modified only as cultivar.
