The assessment of agrobiological parameters of wild strawberry varieties in Krasnoyarsk forest-steppe conditions

The research purpose was the assessment of agrobiological parameters of wild strawberry varieties in Krasnoyarsk forest-steppe conditions. The objects of experiment were varieties: Elista - control, prototypes - Pervoklassnitsa, Solnechnaya polyanka, Feerverk, Zefir. Nitrate nitrogen was determined by special method (State standard specification 26488-85), mobile phos-phorus - by Chirikov's method in modifications of (State Standard 26904-91), hydrolytic acidity - by Kappen's method in modification according to special recommen-dations (State Standard 26212-91). On high winter har-diness varieties Zefir and Feerverk were allocated: freezing was missing. In all studied varieties excellent general condition of plants (September) in 2015-2016 was observed. For the beginning of vegetation period (June), 2017 of the plant were underdeveloped. The greatest productivity was recorded in the varieties Pervoklassnitsa - 22.9t/hectare and Feerverk - 21.6 t/hectare. For three periods of vegetation (2015-2017) in studied varieties the symptoms of diseases and damag-es by wreckers were not observed. According to the degree of large fruit of berry specimens Pervoklassnitsa, Feerverk, Solnechnaya polyanka were very large (15.5-18.0), variety Zefir - large (12.6 g) and berries of control variety Elista - average, by the size (6 g). The assess-ment of berries according to flavoring characteristics showed the advantage of varieties Feerverk and Zefir. The greatest content of vitamin C was in berries varie-ties Zefir - 51.2 mg/%. In the complex of agrobiological indicators for cultivation in the conditions of the Krasno-yarsk forest-steppe variety Feerverk was allocated.
