Resistance of the red currant seedlings to redhead aphid

Aphid (Cryptomyzus ribis L., syn. Capitophorus ribis L.) is one of the dangerous pests for red currants. The aim of the research was to study the level of resistance of hybrid red currant seedlings to this pest and select seedlings combining high aphid resistance with other valuable traits. The observations were conducted in 2015…2017 on the selection plot at the Russian Research Institute for Fruit Crop Breeding (Orel region). 299 hybrid seedlings of 7 crossing combinations and 96 outbred seedlings were studied. When estimating the degree of seedling damage by aphid, we were guided by “Program and methodology of variety investigation of fruit, berry and nut crops”. The evaluation was carried out on a 5-point scale, where 0 points – no signs of damage; 5 points – severe damage (the loss of over 75% of leaf surface). High resistance to Cryptomyzus ribis L. was observed in hybrid families OS 120-15-77 × Niva, OS 984-21-84 × Niva and in the population from the open pollination ELS 1662-31-100 (Niva × OS 1097-25-118). Niva is a promising initial genotype in breeding for resistance to Cryptomyzus ribis L. The offspring of breeding families Belaya Potapenko × OS 1426-21-80 and Dana × Svetlitza turned out to be the most susceptible to this pest. On the basis of the hybridological analysis, it can be assumed that the resistance to Cryptomyzus ribis L. in red currants is polygenic. We have allocated seedlings of different genetic origin that combine resistance to Cryptomyzus ribis L. with other valuable traits which are of interest for breeding.
