Comparison of fruit quality of five mandarin cultivars grown in the Neretva region

Mandarin (Citrus reticulata Blanco) has an important place in Croatia fruit production and is an important export product. The aim of the research was to compare the fruit quality at harvest of five varieties of mandarin (‘Chahara’, ‘Kawano Wase’, ‘Owari’, ‘Saigon’ and ‘Zorica’) grown in the Neretva Valley. The fruit were harvested according to the standards of Neretva producers. Fruit quality was determined by firmness, soluble solids content, total acids, the ratio of soluble solid content to total acids and color. The varieties ‘Chahara’ and ‘Zorica’ had the highest fruit firmness (4.28 kg cm-2 and 3.98 kg cm-2). Varieties ‘Chahara’ and ‘Zorica’ in comparison with other varieties had more soluble solids content (12.43% and 13.02%) and total acids (2.06% and 2.38%). However, these cultivars also had the most unfavorable ratio of soluble solids content and total acids (6.25 and 5.62), while the cultivars ‘Kawano Wase’ (9.20) and ‘Owari’ (11.47) had the most favorable ratio. The ratio of soluble solids content to total acids is the main indicator of mandarin ripeness and should be around 10: 1. The earliest observed varieties are ‘Chahara’ and ‘Zorica’, and the latest are ‘Owari’ and ‘Saigon’. Varieties ‘Chahara’ and ‘Zorica’ are of poorer fruit quality, which is probably caused by shorter vegetation (early ripening) and premature harvest in the desire to put the fruit on the market as soon as possible. The varieties ‘Kawano Wase’, ‘Owari’ and ‘Saigon’ are the leaders in terms of fruit quality among the observed varieties.
