Abstract
Health condition of the citrus planting material is one of the main factors of its quality. Field researchers and laboratory analyses in the the Neretva valley, the most important citrus cultivation area in Croatia, have identified that majority of mother trees is infected with the Citrus Tristeza virus, which causes a decrease in plant fertility. This problem has been present for many years now, mostly because buds are CAC category (Conformitas Agraria Communitatis), which means they originate from already infected trees. Mother blocks of higher categories, based on the EPPO scheme, have not been established yet. Raising this kind of mother blocks is necessary for the production of healthy reproductive planting material, and it is included in European Union Council directive (2008/90/EZ) on the marketing of fruit plant propagating material and fruit plants intended for fruit production. This was the starting point in initiating the Project „Establishment of mother blocks of citrus, pome fruits and stone fruits in the Republic of Croatia“ by the Ministry of Agriculture. Propagating the fruit material produced in this way will allow increase of the citrus plantations productivity and higher pomological value. In this article, the procedure of the certification scheme is analyzed through examples of Spain and Italy, leading European citrus producers, along with the available scientific literature.
