Abstract
Rubus fructicosus L. is a fruiting plant of the genus Rubus, subgenus Rubus, in the Rosaceae family.
Species from within genus are adapted to a wide range of environments, from within the Arctic Circle to the tropics, from low to high altitude, from acid to alkaline soils, from very wet to very dry climates (Bailey, 1923; Darrow, 1937, 1967; Sherman and Sharpe, 1971; Lawrence, 1986b; Jennings, 1988; Hummer, 2017). Fruit quality characteristics were studied for three consecutive years in 21 blackberry genotypes grown in a Romanian climate.
Physical parameters studied included yield, berry weight (BW), shape index (SI), and firmness.
The chemical parameters studied were soluble solids content (SSC), acidity, vitamin C, anthocyanins, pH, and total polyphenol content (TPC). The results showed that fruit weight varied between 7.58 g (‘13-7-31’ hybrid) and 4.60 g (‘13-2-3’ hybrid), total soluble solids reached a maximum 16.15 °Brix (‘13-7-9’ hybrid) and a minimum 10.44 °Brix (‘13-7-20’ hybrid), the content of vitamin C oscillated between 41.3 mg 100 g-1 (‘13-1-22’ hybrid) and 13.56 mg 100 g-1 (‘13-7-9’ hybrid), total polyphenols content had a maximum 465.77 mg GAE 100 g-1 (‘13-7-9’ hybrid) and a minimum 296.50 mg GAE 100 g-1 (‘13-1-35’ hybrid). Most of the genotypes exhibit good adaptation capabilities and respectable fruit quality traits, and also have good potential as a commercial crop for both fresh and processing markets, as well as for future breeding programs.
