Classification of Citrus• The genus citrus contains many kinds
or types that differ as to their fruits, flowers, leaves and twigs.
• The arranging of the kinds of citrus into groups is termed classification.
• The naming of these groups with valid names is termed nomenclature.
• There are definite international rules of nomenclature but not of classification.

Classification of Citrus• Several persons have classified
citrus into different groups and given them valid names.
• The classification one accepts is one of personal choice, based on utility, common usage and natural relationships.
• Classification of genus citrus is a very complicated and problematic one.

Classification of Citrus• Since 19th Century, several
taxonomists tried in their own way to classify the genus citrus.
• Many scholars in the past and present tried to give some solution to the problem, which is agreeable to one and all.
• However, till to date no perfect solution was given.
• Each classification has its own merits and demerits.

its hardiness to cold and resistance to several diseases, but due to intolerance to Tristeza it has been abandoned as rootstock.
