The purpose of the research was to identify genetic sources of resistance to abiotic environmental factors. The assessment of the raspberry source material was carried out in 2017-2021. The study included 40 varieties and 20 hybrid forms of raspberry. It is established that under simulated conditions, the selected form 1-188-1 has high resistance to temperature -35°C in the middle of winter (II component). Sources of resistance to frost -22oC after the thaw (III component) are varieties Ulybka, Meteor and forms 1-15-1, 1-4-2. The varieties Ivan Kupala, Ulybka and selections 1-188-1, 1-4-2, 6-125-4, 8-10x-1 with freezing up to 1.6-2.1 points were distinguished by the greatest resistance of the buds for the IV component of winter hardiness. The Penguin, Yubileynaya Kulikova varieties and selections 8-189-1, 3-40-14, 44-154-2, 1-180-2 with full ripening of the crop and a relatively short fruiting period (48-55 days) are of interest for further breeding for early ripening of the primocane raspberry. In breeding for high drought and heat resistance, the varieties Gusar, Ulybka, Poklon Kazakovu, Medvezhonok, Gerakl and selected forms 37-143-3, 11-107-1 are promising, combining several indicators of the water regime at the optimal level.
