Stability of Fruit Quality Traits of Different Strawberry Varieties under Variable Environmental Conditions

Abstract

Strawberry fruit quality traits can be affected by genotype–environment interactions, determining the final consumer acceptance of fruits. Trait stability under varying environments is necessary to ensure the fruit quality of strawberries selected by breeding programs. Hence, inter- and intra-annual variation of organoleptic and functional fruit quality parameters of five strawberry varieties throughout four consecutive cropping seasons was analyzed to assess their relative stability. In most varieties, organoleptic parameters showed higher inter-annual stability but greater variability throughout the season, while the reverse was true for the functional quality parameters. Relative humidity and mean and minimum temperatures partially accounted for fruit quality variation but other factors along with the genotype may also have an influence. Among the varieties, ‘Splendor’ displayed greater year-on-year stability in organoleptic parameters, and ‘Sabrina’ and Candonga® showed higher inter- and intra-annual stability on functional fruit quality, respectively. Environmental variation did not affect fruit quality parameters similarly in all strawberry varieties. In ‘Sabrina’ and Candonga® antioxidant capacity (TEAC) was greater and stable throughout the cropping season, underlining TEAC as a tool for varietal selection, and suggesting these two varieties as parents for breeding programs that seek healthy features and high-quality fruits that meet consumer demands.

Influence of Post-Flowering Climate Conditions on Anthocyanin Profile of Strawberry Cultivars Grown from North to South Europe

“…Thus, the total anthocyanin contents in strawberry are both qualitatively and quantitatively known to be strongly influenced by the genotype (among others [9][10][11][12][13][14]) and likewise, by external factors such as high or low temperature and light (photoperiod, quantity and wavelength including UV-light). Recent review articles have highlighted the influence of temperature and light on the synthesis and accumulation of plant secondary metabolites including anthocyanins [15][16][17].…”

Genetic analysis and cross associations of strawberry (Fragaria × ananassa) genotypes and morpho-biochemical features: a practical breeding program

“…However, strawberry yield and the yield components stayed positively correlated based on either genotypic or phenotypic correlations, but with signi cantly different values. (Cervantes et al, 2020) and (Gabriel et al, 2018) in their study on different strawberry cultivars showed that environment has a great effect on the variability of the traits. Saed-Moucheshi (2018) by focusing on traits' relationship under different environmental conditions showed that under normal condition the variability among traits was higher than that under stress condition, which supports our results of changes in genotypic and phenotypic correlation coe cients.…”

“…In addition, the availability of genetic diversity within compatible genetic resources, including wild species and domestic cultivars will enhance the extent of any improvement (Lot et al, 2014;Saed-Moucheshi et al, 2021). Breeding value, the amount heritability in a feature, can be deduced from the phenotypic and genotypic value for key desirable traits, as well as from the heritability and genetic advances value of the parental lines (Moucheshi et al, 2011;Vosough et al, 2015;Cervantes et al, 2020).…”

Use of New BTH Derivative as Supplement or Substitute of Standard Fungicidal Program in Strawberry Cultivation

“…is a popular species of berry plants, cultivated all over the world. The fruits of this species are highly appreciated as a source of macro-and microelements, vitamins, and prohealth antioxidants [21][22][23]. The annual production in recent years has reached 9.2 Mt [24].…”
