Abstract
The article presents the results of studying the black currant varieties collection of the Kokinsky control station of the FSBSI FRC for Horticulture (Bryansk region) for winter hardiness, resistance to Sphaerotheca, and currant gall mite in order to create new initial forms based on the selected genotypes, characterized by a high level of adaptation for their inclusion in the breeding work to improve the crop assortment. The best combinations of crosses (Gamayun × Nara, 33-27-1 × Kipiana, 33-27-1 × Bryanskiy Agat, Favorit × Dar Smolyaninovoy, etc.), the initial forms for inbreeding and free pollination, in the progeny of which the largest number of winter-hardy seedlings, characterized by resistance to Sphaerotheca and gall mite, were identified. Promising winter-hardy Sphaerotheca-resistant forms were identified 4-63-4, 72-03-7, 3-37-26/02, 62-03-7, 1-5-1, 63-35-1, 3-134-01, 28-03-1, 5-82-02, 1-91-01, immune to gall mite.
Highlights
One of the most popular and affordable berry crops is black currant (Ribes nigrum L.), the therapeutic and nutritional value of which is well known to everyone
Many of these agents are natural antioxidants that help to increase the resistance of the human body to stress factors [1]
Based on the wet weight, black currant berries contain an average of 160-240 mg/100 g of ascorbic acid, up to 1500 mg/100 g of phenolic compounds [2, 3]
Summary
One of the most popular and affordable berry crops is black currant (Ribes nigrum L.), the therapeutic and nutritional value of which is well known to everyone. The increased interest in this crop is explained by the fact that its fruits are rich in biologically active agents, trace elements, essential oils and play an important role in human nutrition. Many of these agents (vitamin C, β-carotene, bioflavonoids cyanidin-3-glucoside, delphinidin-3rutinoside, etc.) are natural antioxidants that help to increase the resistance of the human body to stress factors [1]. Based on the wet weight, black currant berries contain an average of 160-240 mg/100 g of ascorbic acid, up to 1500 mg/100 g of phenolic compounds (anthocyanins, catechins, leucoanthocyanins and other biologically active substances) [2, 3].
