Golden currant assortment evaluation on resistance to gallic aphid in the conditions of Bashkiria

The purpose of research is to study the available promising varieties of golden currant, located in the Kushnarenkovskiy breeding center, in terms of resistance to two types of aphids (Aphis grossulariae Kalt. and Cryptomyzus ribis Linnaeus). The study of varieties and hybrid forms of golden currant in terms of resistance to aphids was carried out in the field against a natural background for 6 years in the period from 2017 to 2022 on the collection and breeding plots of planting in 2008-2016 of the Kushnarenkovskiy breeding center for fruit and berry crops and grapes of the Bashkir Research Institute of Agriculture. Planting scheme 4 2m, in 3 repetitions in each variant. Accounting of plants for resistance to gooseberry shoot and gallic leaf aphids was carried out visually for each bush during the entire growing season according to the program and methodology for the study of fruit, berry and nut crops. 20 promising varieties were studied. The degree of damage to the leaves was noted in points: 0 - no signs of damage; 1 - very slight damage to single leaves; 2 - slight damage (up to 10 % of leaves); 3 - medium damage (up to 30 % of leaves); 4 - strong damage (from 30-50 %); 5 - very severe damage (more than 50 %). The following varieties were noted with the least damage by the pest: Shafak, Fatima, Nakhodka, Zarina, Viola, № 2-6,№ 1-1, № 1-2, № 1-2-8, № 4-1, № 2-86, № 2-8, № 3-3, № 3-2, № 5-2, № 3-1, № 5-16, the average damage over the years of the study did not exceed 1.1 points. The listed varieties and selected forms are recommended for use in breeding for resistance to aphids, for cultivation in amateur gardening in the conditions of the Bashkir Cis-Urals.
