The paper presents the results of a study on pear varieties under the conditions of the monsoon climate in the southern coastal zone of Primorsky krai. The research goal was to select frost-resistant varieties with tasty fruits for growing and increasing the breeding assortment. Seventeen varieties originating from Altai, Ural, and Moscow regions were tested in 2017–2024 and compared to varieties from the Russian Far East. It had been established that newly introduced varieties remained less frost-resistant than local varieties related to Pyrus ussuriensis. Varieties Shuranovka 5 and Tyoma were used for comparison. The varieties were evaluated for frost and disease resistance and taste. Varieties Raya, Kitaika medovaya, and Khorup stood out for a complex of traits as new promising local varieties. Among varieties from other regions, variety Gvidon of the Ural breeding origin was selected; it survived during the whole period of experiments and preserved high frost resistance, yield, and taste. Early-maturing productive variety Obil'naya from Moscow region had a high positive score as well. It can be selected for creating an orchid of intensive-type for short-term use and harvest (4–5 years).
