“…Limited genetic studies have been conducted on strawberry texture, and this may be due to the complexities associated with quantifying the trait. Nonetheless, texture has been reported to play a significant role in the overall fruit quality score of strawberries (Cockerton et al, 2020), therefore, the desirable texture of strawberries must continue to be selected for despite the associated challenges.…”

Over the last two centuries, breeders have drastically modified the fruit quality of strawberries through artificial selection. However, there remains significant variation in quality across germplasm with scope for further improvements to be made. We reported extensive phenotyping of fruit quality and yield traits in a multi-parental strawberry population to allow genomic prediction and quantitative trait nucleotide (QTN) identification, thereby enabling the description of genetic architecture to inform the efficacy of implementing advanced breeding strategies. A negative relationship (r = −0.21) between total soluble sugar content and class one yield was identified, indicating a trade-off between these two essential traits. This result highlighted an established dilemma for strawberry breeders and a need to uncouple the relationship, particularly under June-bearing, protected production systems comparable to this study. A large effect of quantitative trait nucleotide was associated with perceived acidity and pH whereas multiple loci were associated with firmness. Therefore, we recommended the implementation of both marker assisted selection (MAS) and genomic prediction to capture the observed variation respectively. Furthermore, we identified a large effect locus associated with a 10% increase in the number of class one fruit and a further 10 QTN which, when combined, are associated with a 27% increase in the number of marketable strawberries. Ultimately, our results suggested that the best method to improve strawberry yield is through selecting parental lines based upon the number of marketable fruits produced per plant. Not only were strawberry number metrics less influenced by environmental fluctuations, but they had a larger additive genetic component when compared with mass traits. As such, selecting using “number” traits should lead to faster genetic gain.

“…В последние годы наблюдается повышенный спрос на ягоды малины, цена на которые превышает смородину черную, смородину красную и землянику. Это связано, в первую очередь, с высокими вкусовыми и питательными свойствами плодов, а также богатым содержанием БАВ, лечебными и профилактическими свойствами [1]. По данным FAOSTAT, в период с 2017 по 2019 год рост валового сбора ягод малины в России составил более чем 40 тысяч тонн 1 .…”

The aim of the research is to search new sources of the main economically valuable traits for further breeding of raspberry. Nineteen previously created selected forms were studied for winter resistance components under controlled conditions, for resistance to major fungal diseases, productivity components, strength and biochemical composition of fruits. The zoned Gusar variety was used as the control. The work was carried out in 2018-2020 according to generally accepted techniques. Artificial freezing of raspberry stems was carried out in the climate chamber TH-6 JEIO TECH. According to the results of the studies, selected forms 8-10х-1, 6-125-4, which have an increased resistance to certain components of winter resistance, have been identified. Hybrids 2-115-1 and 1-188-1 have cumulative resistance to winter damage factors. Based on the integrated resistance of raspberry hybrids to the main fungal diseases, new sources have been revealed: forms 1-124-1, 2-115-1, 2-115-2, 1-111-21, 1-8-2, 2-35-1, 2-90-3, 6-125-4, 3-4-2, 8-10х-1, 4-33-21 and 4-122-2. The degree of their damage did not have a significant influence on winter hardiness, productivity and quality of berries. As the result of study of components of the raspberry productivity, selected forms (1-111-21, 2-90-2 and 2-90-3), forming fruits with an average weight of more than 4.0 g, and genotypes with large and one-dimensional fruits (1-176-21, 2-35-1, 4-33-21, 1-124-1) not growing smaller from picking to picking were identified. The highest potential productivity was noted for selections 2-115-1, 1-111-21, 1-188-1, 4-46-2, 2-90-2 and 2-90-3, capable to form a yield of more than 1.3 kg per bush. The selections 1-124-1, 2-90-2 and 2-90-3 are distinguished by an increased strength of the fruits. They form fruits with a crushing force exceeding 5.0 N, which ensures the safety of integrity and transportability when manually harvested. No complex sources of increased accumulation of biologically active substances have been identified. Genotypes with a high content of individual biochemical substances were selected. The highest accumulation of soluble solids and sugars was noted in the samples 2-90-3, 18-11-4 and 2-115-1. Highest accumulation o the vitamin C was observed in the samples 6-125-4 (59.8 mg/100 g) and 2-90-3 (61.5 mg/100 g). As new sources in breeding to improve the taste characteristics of raspberry, it is necessary to use selected forms 2-90-2, 2-115-1 and 6-125-4, approaching in taste to the standard variety Novost Kuzmina. Selected forms 2-90-2, 2-90-3 and 2-115-1 are new sources in raspberry breeding, combining a complex of economically valuable traits at a high level.
