Constraints and challenges on raspberry production in Serbia

The Republic of Serbia is one of the world’s leading producers and exporters of raspberries, with an average annual production of 117,214 tons in the last five years. More than 90% of raspberries produced are exported frozen to foreign markets, while the export of fresh raspberries is almost negligible. Although the total area under raspberry cultivation has increased to 20,807 ha, the average yield per hectare has steadily decreased and in 2021 was 5.3 tons (FAOSTAT, 2023). Raspberry production is concentrated in the western and southwestern parts of Serbia mainly on small farms with an average area of 0.25 ha. ‘Willamette’ is still the predominant floricane fruiting cultivar in raspberry plantations, occupying more than 90% of the total area under cultivation. The main reason for the slow replacement of this cultivar by the new and better cultivars is the high demand of the Western European processing industry for its dark red and delicious fruits, which are mostly exported frozen to foreign markets. The floricane fruiting cultivars ‘Meeker’ and ‘Fertödi Zamatos’, suitable for both frozen and fresh consumption, are slowly spreading and currently account for 3-5% of the total cultivated area. Other cultivars, such as ‘Tulameen’ and ‘Glen Ample’, which are suitable for fresh consumption, are grown only on a small scale, as there is no organized export of fresh raspberries from Serbia. Recently, primocane fruiting cultivars ‘Enrosadira’ and ‘Kwanza’ have been spread in protected environments (greenhouses) to meet the growing needs of producers and consumers. These cultivars continually set fruit on the current season's canes from mid-July to fall and in early June on the previous season's canes, extending the harvest season and providing the total yield of the two crops to exceed 30 tons per hectare. In contrast, average yields of floricane fruiting raspberry cultivars vary and range from 5 to 20 tons per hectare, depending on the orchard management. The floricane fruiting cultivars are cultivated in the vertical trellis system consisted of pillars with two wires and an additional support for long fruiting branches, while the primocane fruiting cultivars are grown in the hedgerow system with additional trellises, depending on the vigor and yield potential of the cultivar. Main constrains in raspberry production include: the poor quality of planting material; the choice of unsuitable locations for establishment of new plantations; the adverse effects of climatic factors; the lack of field extension services and, accordingly, inadequate management of raspberry plantations. The challenges in raspberry production are related to the development of new cultivation techniques through the use of soilless systems, anti-hail nets, rain shelters, and plastic tunnels to avoid unfavorable climatic and soil conditions, and infestation with various fungal diseases.

H καλλιέργεια της φράουλας στην Ελλάδα: νέες προκλήσεις και προοπτικές ανάπτυξης μέσω προγραμμάτων γενετικής βελτίωση για την ανάπτυξη νέων ποικιλιών

Η Ελλάδα είναι μια από τις πιο σημαντικές ζώνες για πρώιμη παραγωγή φράουλας στην Ε.Ε. Το 2022/2023 καλλιεργήθηκαν 20000 στρέμματα με αξία προϊόντος περισσότερο από 150 εκατ. €. Παρόλο που διαθέτει συγκριτικά πλεονεκτήματα, στερείται δικών της ποικιλιών φράουλας. To υπάρχον μοντέλο παραγωγής βασίζεται σε διεθνείς ποικιλίες, τα χαρακτηριστικά των οποίων είναι προσαρμοσμένα στις απαιτήσεις των χωρών που αναπτύχθηκαν. To πρόγραμμα ανάπτυξης ποικιλιών της Berryplasma στοχεύει στην δημιουργία γενοτύπων φράουλας οι οποίοι να συνδυάζουν βελτιωμένα παραγωγικά χαρακτηριστικά (πρωιμότητα, μέγεθος καρπού, συνολική παραγωγή) και ποιοτικά χαρακτηριστικά όπως μετασυλλεκτική διάρκεια ζωής του καρπού και υψηλό % εμπορευσιμότητας. Στα πλαίσια του προγράμματος έχουν αναπτυχθεί 4 ποικιλίες, 3 Short day (Kallisti, Elektra and Phaedra) και 1 Day neutral (Aethra) απόλυτα προσαρμοσμένων στις συνθήκες την Νοτίου Ευρώπης συνδυάζοντας ταυτόχρονα όλα τα επιθυμητά εμπορικά και ποιοτικά χαρακτηριστικά.
