Sažetak
Pomological characteristics of traditionally grown, indigenous orange (Citrus sinensis L.) Osbeck) cultivars from southern Croatia (Dubrovnik area) were studied. Ten accessions of oranges were collected (‘Trstenka’, ‘Ludača’, ‘Katarinka’, ‘Puh’, ‘Jaffa’, ‘Ljuta naranča’, ‘Bezimena’, Katarinka 2’, ‘Crvena’, ‘Ljetna’), and described according to IPGRI citrus fruit descriptors. Statistically significant differences were found among the analysed accessions. Fruit weight varied from 85.41 g to 193.09 g, with ‘Katarinka’ accession having the highest fruit weight. Oval fruit predominated, with peel colour ranging from light to dark orange with red pigments. Accession ‘Ludača’ had the thickest peel, and the peel weight was 54.10 g. The lowest peel weight was recorded in accession ‘Jaffa’. The uniform orange colour of fruit flesh was observed in all accessions, except for ‘Crvena’ which has red pigmented fruit flesh. The fruit flesh texture of the accessions studied was not significantly different. Significant differences between accessions were found in juice yield and varied from 52.48 to 35.19 %. The Total soluble solid (TSS) of ‘Bezimena’ was 14.4˚Brix, followed by ‘Jaffa’ (12.8˚Brix) and ‘Crvena’ and ‘Katarinka’ (11.8 ˚Brix). The highest total acidity (TA) was recorded for ‘Ljuta naranča’ (24.5 %), ‘Jaffa’ (12.1 %) and ‘Bezimena’ (9.98 %), while the highest TSS/TA ratio was recorded for ‘Ljetna’ and ‘Trstenka’. The results of this research contribute to the scientific understanding of the differences between selected indigenous orange accessions in the Dubrovnik area. Greater recognition of indigenous Dubrovnik oranges by customers and producers may eventually lead to increase planting and production of these cultivars as the authenticity of these cultivars areincreasingly appreciated.
