In this paper we consider the second component of remontant raspberry cold hardiness - frost resistance, namely the ability of this raspberry type to tolerate the lowest temperature. Series of artificial freezing was carried out to check the frost-resistance. According to the data obtained the most frost-resistant varieties of remontant raspberries were detected. The critical low temperature for all studied varieties and forms of remontant raspberries was estimated.

Key words: remontant raspberry, varieties, frost resistance
