DETERMINING CONSUMER APPEAL OF SELECTED GARDEN STRAWBERRY VARIETIES (FRAGARIA × ANANASSA DUCH.)

Abstract

Improving the biochemical strawberry fruit composition and aroma is an important goal to develop the assortment of strawberry plants because only a few present-day varieties combine the high quality and aroma in strawberry fruits with increased accumulation of the biochemical composition components. The paper aims to assess hybrid strawberry seedlings based on a range of properties in strawberry fruits to select the most promising genotypes. Strawberry aroma and its consumer appeal were evaluated organoleptically. The biochemical component was tested in the laboratory according to standard methods, and the strawberry aroma was evaluated using DNA markers. The research identified promising genotypes showing a high level of different characteristics: 75-30 (Tokado × Elianny) – consumer appeal (5.0 points), flavor (4.5 points), polychlorinated biphenyl levels [PCB] (9.2% Brix), and vitamin C (72.1 mg/100 g); 34-2 (922-67 × Privlekatelnaya) – consumer appeal (5.0 points), strawberry aroma (FaOMT gene), flavor (4.5 points), РСВ levels (14.7% Brix), and sugars (10.8%); 153-41 (Senga Sengana × Redcoat) –consumer appeal (5.0 points), strawberry aroma (FaOMT gene), PCB levels (12.8% Brix), sugars (10.2%), and vitamin C (76.1 mg/100 g); 153-60 (Senga Sengana × Redcoat) – consumer appeal (5.0 points), strawberry aroma (FaOMT gene), flavor (4.6 points), PCB levels (11.7% Brix), and sugars (10.5%); 35-16 (922-67 × Maryshka) – flavor (4.6 points) and anthocyanins levels (90.7 mg/100 g); 72-25 (Privlekatelnaya × Bylinnaya) – combination of FaOMT and FaFAD1 strawberry aroma genes.
