The paper presents the results of studying 58 peach cultivar-samples in the collection of the Russian Research Institute of Floriculture and Subtropical Crops for 12 years (2007–2018). The existing peach assortment was updated due to 10 selected perspective cultivars and clones: cultivars – ‘Springgold’, ‘Medin Red’, ‘Earley Blow’, ‘Summerset’, ‘Comanche’, ‘Fayette’ and clones – ‘Ranniy Collins’ (‘Nicolai I’), ‘Rannyaya zarya’, ‘Krasnaya zarya’ and ‘Larisa’. In 2018, clone ‘Larisa’ was included into the State Register of Selection Achievements of the Russian Federation. The new presented cultivars and clones provide a fresh fruit conveyor for 2.5 months, both due to early cultivars (‘Springgold’) and later (‘Fayette’), as well as cultivars and clones whose fruits ripen between the main industrial cultivars: ‘Favorita Morettini’, ‘Collins’, ‘Redhaven’, ‘Veteran’. The allocated promising cultivars and clones are the most productive with high commercial qualities of fruit, not very demanding for cold in winter and heat in spring, which are limiting factors for the successful peach cultivation in the Russian subtropics. The method of estimating the lack of cold for peach in the winter is specified.
