The study describes a brief history of selective work and gooseberry sort tests in Krasnoyarsk Region. Com-parative characteristic of varieties was carried out on Shushensky fruit and berry sort testing site for the peri-od from 2012 to 2017. The assessment of the following varieties was carried out: Konfetny - control, Narodny, Uralsky Izumrud, Shershnevsky. The interval of matur-ing of gooseberry berries made 9 days. The first berries of the variety Uralsky Izumrud (23.07), in other varieties - on July, 27 - on August, 2 ripened. All varieties showed good and excellent extent of berries maturing testifying to the fitness of varieties to climatic conditions of the area. Konfetny (control) appeared to be the most winter-hardy in relation to other varieties. Weak freezing of the varieties Shershnevsky and Narodny in single one-year old branches was noted (about 1 %). Winter hardiness of the variety Uralsky Izumrud was average. Gooseberry varieties research on the extent of defeat by diseases showed, that all sorts had field hardiness towards mil-dew. Septoria spot was discovered in all the sorts. The smallest point of defeat was in the variety Shershnevsky (2 points), the greatest was in the variety Uralsky Izumrud (3 points). The anthracnose defeat in not signif- icant degree was discovered in 2017 (3 points). The biggest damage was recorded in Konfetny and Shershnevsky varieties. The least point of defeat was in Shershnevsky variety (2 points), the most one was in Uralskiy Izumrud (3 points). Among these testing sorts, Shershnevsky variety was pointed out due to some characteristics, such as winter stability, harvest ability, disease stability. Freezing of this sort was insignificant, just single one-year old branches (1 %), the productivity was 1.9 t/hectare. Shershenevsky variety had the least point of septoris damaging (2 points) in comparison with Konfetny control sort. Shershenevsky and Uralsky Isumrud varieties had bigger berry sizes - 2.6 and 3.0 g respectively. The highest tasting point was also got by these sorts: Uralsky Izumrud - 4.7 points; Shershenevsky - 4.6 points. The work on sort testing of introduced gooseberry varieties on the territory of Kras-noyarsk Region is continued, the selection and studying of high-winter-hardy, sphere resistant, productive and low-pricking sorts varieties which will expand add al-ready available assortment of this culture across Kras-noyarsk Region are performed.
