Comparison of fruit quality parameters of different raspberry (Rubus idaeus L.) genotypes cultivated in Estonia
The main aim was to compare the fruit weight and biochemical fruit quality (soluble solids, titratable acids, ascorbic acid, total polyphenolics and anthocyanins) in the older and recently selected raspberry genotypes cultivated in nordic climatic conditions.
The experiment involved seven red-fruited raspberries: 11-02-12, 11-02-15, Aita, Glen Ample, Maurin Makea, Norna, Novokitaivska, and one yellow-fruited raspberry genotype Helkal. The data were collected in three years (2016-2018) at the Polli Horticultural Research Centre of Estonian University of Life Sciences (58°0744.5N; 25°3216.8E), Estonia.
The results showed that genotypes Glen Ample, Aita, 11-02-15 and Norna produced significantly larger fruits when compared to other tested yellow- and red-fruited raspberries.
The fruits of genotype Maurin Makea contained significantly higher amount of ascorbic acid when compared to Norna and Novokitaivska. The highest content of polyphenols was found in the fruits of genotypes Norna, Novokitaivska and 11-02-15, and anthocyanins in Norna.
