Varietal Change Dominates Adoption of Technology in Spanish Citrus Production

Abstract

After describing the technology adopted and its influence on production and yield, the importance of varietal change, which is essential to meet demand, is underscored. The choice of a variety by growers depends on the expected price it will fetch along with the commercial and crop characteristics and the quality. Survival of a variety in the marketplace depends on the performance as expected and on the existence of other more competitive varieties. First, in Spanish citrus farming, the navel group predominate, with 41.10% of orange production, in which the main varieties are “Navelina” and “Lanelate.” The group of late white oranges is also important. The mandarin orange group includes clementines and mandarin hybrids; lemons also feature prominently. In sweet oranges, the navel group and late white group has often been renewed with varieties from the same group. In very early clementines varieties, the survival of which is usually short, the supply of new varieties is excessive. Because of its commercial characteristics and harvesting time, the group with the highest expansion possibilities are the mandarin hybrids which are in demand by hypermarkets. In the introduction of varieties, in recent years we have seen varietal clubs being established, with area control of each variety and very strict rules on cultivation and marketing.

Disease Resistant Citrus Breeding Using Newly Developed High Resolution Melting and CAPS Protocols for Alternaria Brown Spot Marker Assisted Selection

“…Bassimba et al [17] reported a drastic reduction in the production of 'Fortune' in the Valencian community (Spain), from 161.000 t to 21.000 t, from the first ABS outbreak in 1998 until 2012. More recently, de-Miguel et al [18] reported the almost complete disappearance of 'Fortune' in Spain due to its ABS susceptibility.…”

Short Communication: Variations of morphology, anatomy, and metabolite profiles of Citrus reticulata Blanco cv. Tawangmangu grafts produced by shoot tip grafting using several rootstocks

“…Citrus production in Indonesia has not been able to meet the domestic demand and the expected additional income. This situation promotes the exploration of potential Citrus species and cultivars for selection programs to improve the yield and the subsequent income (De-Miguel et al 2019).

Effect of Rootstock on the Fruit Quality of Mandarins "Clemenules" and "Tango", and Blood Oranges "Tarocco Rosso" and "Moro"

“…When introducing a new variety into a specific production area, it is important to know its behaviour in rootstocks that, given their traits, can be beneficial. The varietal group of hybrid mandarins has gradually made its way in Spanish citrus production through the commercial space left open by clementines later (De-Miguel, Caballero & Fernández-Zamudio, 2019). Of these, 'Tango' is a recent cultivar that is being introduced as an interesting mid-late season mandarin into the Mediterranean production area.…”

“…3). 'Clemenules' are the most representative cultivar of clementines (De-Miguel, Caballero & Fernández-Zamudio, 2019). As with most clementine varieties, 'Clemenules' is considered an early mandarin (García-Sanchez et al, 2016), and is harvested from early September to late December.…”
