Creation and Use of Highly Adaptive Productive and Technological Red Currant Genotypes to Improve the Assortment and Introduction into Different Ecological and Geographical Zones

Abstract

Global climate change with the cyclicity of natural and climatic processes in the growing season of berry plants, causes weakening at the defense system to (a)biotic stressors, which actualize the need for accelerated cultivar-improving breeding. A new hybrid red currant material was obtained and studied by the method of interspecific hybridization. Correlation analysis was used to assess the relationship between adaptively significant and economical and biological traits. To assess intergenotypic variability, hierarchical clustering was used according to the studied features, which allowed combining three standard methods of multidimensional data analysis. Genotypes adapted to different stressors were identified. The genotypes 271-58-24, 44-5-2, 261-65-19, and ‘Jonkheer van Tets’ were found to have a higher ratio of bound water to free water as compared with the others. Moreover, the genotypes of 271-58-24, 261-65-19, 77-1-47, and ‘Jonkheer van Tets’ were found to have less cold damage during the cold periods. The two most productive genotypes were found to be the genotypes 44-5-2, 143-23-35, and 1426-21-80. A dependence of yield on the beginning of differentiation of flower buds, which led to the abundance of flower inflorescences, was revealed. Rapid restoration of leaf hydration ensured successful adaptation of genotypes to the “temperature shock” of the growing season. The genotypes 271-58-24 and ‘Jonkheer van Tets’ were then observed to be far from the test traits and none of these traits were observed to characterize these two genotypes. The genotypes of 261-65-19 and 77-1-47 were then observed to be characterized by their high stability to Cecidophyopsis ribis scores. Genotypes 261-65-19 and 271-58-24, obtained with the participation of ‘Jonkheer van Tets’ as the maternal form, showed sufficient resistance to Pseudopeziza ribis and Cecidophyopsis ribis. Overall results suggested that the hydration recovery of red currant plants is significantly important for a yield improvement. A new cultivar ’Podarok Pobediteliam (genotype 44-5-2) was obtained that meets the requirements of intensive gardening and is characterized by high adaptability, productivity, and technological effectiveness.

Evaluation of genetic diversity using iPBS-SCoT marker methods in native hawthorn genetic resources and species ıdentification by using DNA barcoding method

“…In the dendrogram created, the similarity rate of the genotypes was found to be in the range of 0.71-0. Previous studies conducted on different wild edible fruits showed that due to rich gene combination, those plants showed high genetic diversity and adaption (61)(62)(63)(64)(65)(66).…”

Identification of Technological Effectiveness for Mechanized Harvesting of Red Currant Cultivars Based on Bush Morphology and Mechanical Fruit Parameters

“…In connection with the mechanization of berry harvesting, traditional approaches to selecting cultivars and agricultural techniques are changing [17]. The essential characteristics of red and black varieties that meet the requirements for mechanical harvesting are the morphological characteristics of the bush, the yield, simultaneous ripening of the berries, the berry quality, resistance to biotic stresses (especially to Sphaerotheca mors-uvae, Cecidophyopsis ribis), duration of removable ripeness of berries, minimal damage to the bushes by a mechanized harvester [18][19][20][21]. Studies conducted mainly on black currant cultivars show the relationship between crop losses during mechanical harvesting and the harvest period and the prediction of harvesting duration.…”

Assessment of the Influence of Storage Conditions and Time on Red Currants (Ribes rubrum L.) Using Image Processing and Traditional Machine Learning

“…The first red currant crops appeared at the beginning of the 15th century, and it was widely cultivated in gardens in the 16th century [4]. Red currant has become popular and spread as a result of the demand for berries due to their high therapeutic effect, as well as technological efficiency, and economically valuable characteristics [5]. Red currant provides healthful and delicious fruits which are a rich source of organic acids, vitamins, and phenolics with antioxidant and antiradical properties [6,7].…”
