Abstract
Eleven plum landraces (‘G-1’ to ‘G-11’) of unknown origin were segregated and analyzed as single trees in orchards of the western Serbia region during 2020/21. The investigation included the most important agronomic traits such as harvest date, fruit and stone weight, fruit dimensions, surface area, soluble solids and total acids as well as the ratio between these two properties, total phenols and total anthocyanins, antioxidant activity and field resistance to Sharka disease (plum pox virus). The collected material showed a wide range of variability within the studied properties.
The investigated plum genotypes ripened between the July 30 (‘G-1’) and September 15 (‘G-11’). The ‘G-3’ was characterized by the largest fruit (37.12 g), while the smallest fruit was found in ‘G-4’ and ‘G-5’ (11.76 g; 13.39 g). In terms of the fruit chemical composition, the best results were obtained in ‘G-5’ and ‘G-11’ which were characterized by the highest content of soluble solids (20.45%; 21.10%) and ratio between soluble solids and total acids (21.73; 30.14). The smallest content of soluble solids (14.25%) was found in ‘G-9’, while ‘G-3’ and ‘G-4’ had the smallest ratio between soluble solids and total acids (8.53; 9.59) due to the high value of total acids (1.94%; 2.09%). The genotype ‘G-2’ was characterized by the highest content of total phenols (197.50 mg GAE 100 g‑1 FW) and antioxidant activity (63.26%), while the value of total anthocyanins was the highest in ‘G-5’ and ‘G-8’ (17.32 and 18.93 mg C3G 100 g‑1 FW, respectively). The lowest level of bioactive compounds was found in ‘G-3’. Regarding the field resistance to Sharka disease, the assessed genotypes can be divided into three groups: without symptoms (‘G-2’ to ‘G-4’, ‘G-6’ and ‘G-7’), with minor symptoms (‘G-1’, ‘G-8’ and ‘G-9’) and with moderate symptoms (‘G-5’, ‘G-10’ and ‘G-11’).
