Agronomic Characteristics and Chemical Composition of Newly Developed Day-Neutral Strawberry Lines by Agriculture and Agri-Food Canada

Abstract

The agronomic characteristics and chemical composition of seven advanced day-neutral strawberry lines and a commercial cultivar 'Seascape' were evaluated for their horticulture and quality attributes. The results showed that the advanced strawberry lines had the best horticultural characteristics, such as more resistance to diseases, less weight and juice losses and better fruit glossiness during storage, compared to 'Seascape'. Among the advanced lines, FIN005-55 had the better fruit quality with higher soluble solids content (SSC)/titratable acidity (TA) ratio and highest SSC, FIN005-7 had the highest total phenolic content (TPC) and antioxidant capacity (AC), and both had potential for commercial trials.

“…So, Radajewska [28] and Milivojević [29] revealed that 'Marmolada' was characterized by large fruits with the highest weight, whereas the smallest fruits were produced by 'Senga Sengana', which confirmed our data. Strong effect of genotype per se on this property was previously described [30]. As expected, fruit of Fragaria vesca L. (selection 'FA 255/2011') is the smallest than others [31].…”

“…Ripening index also significantly varied among cultivars, being higher in fruits of 'Senga Sengana' and lower in 'Selene'. Variability among cultivars has been previously reported by several authors [30,34].…”

“…Previous study on apricot indicated that origin play an important role in TPC levels [33]. Most of authors reported that berries of blackberry and fruits of strawberry are a good source of TPC and exhibit high antioxidant activity [3,16,30,34,40], whereas red currants contained much lower amounts than that of above two species [13]. For example, Guerrero et al [41] noticed that woodland strawberry had higher TPC and antioxidant activity than cultivated strawberry.…”

“…The quantity of malic acid determined by Skupień and Oszmiański [16] in fully ripe fruit of 'Senga Sengana' was similar to our results. In a study of Wang et al [30] and Djilas et al [38] acidity content significantly differed between cultivars. These authors also reported that, beside others, strawberries with lower fruit weight and acidity, make it an ideal candidate for storage or transportation.…”

“…Since the some evaluated species and their cultivars showed relatively high SSC, they are suitable for both fresh market and juice processing, and all three red currant cultivars and 'May Duke' gooseberry only appropriate for the industry due to its high acidity. Also, the taste and flavour of fruit and/or berries clearly rely on the SSC:TA ratio [30]. Namely, low SSC (consisting mostly of sugars) with high acidity resulted in a tart berry, while low acidity and higher SSC resulted in a blend taste.…”
