In this article we present the results of the evaluation of 20 red currant varieties from NCRRIHV collection. Evaluation of varieties for commercial quality and biochemical composition of berries are presented
We have studied 17 strawberry varieties due to their economically valuable traits: the number of berries (pcs per plant), average fruit weight (g), biological yield (g per plant), firmness of fruit (g). Among the studied varieties is 6 - Honeoye, Alba, Belrubi, Asia, Nelli, Bogota are zoned varieties; 3 - Djeni, Elegia, Kemia is a new varieties of local selection and 8 an introduced varieties from the EU - Joly, Onda, Galia, Vivaldi, Rumba, Florence, Alina, Molling Opal. The purpose of the work is to identify the strawberry varieties which are promising for industrial production in the south of Russia among new strawberry varieties of local selection and introduced varieties. Based on two-factorial analysis of variance according to 2018-2019 studies there were revealed significant differences between the genotypes of varieties for all studied parameters. It is shown that the greatest differences in the variability of traits are observed by the “year” factor. The varieties were ranked according to the values of the smallest significant difference for each individual trait. In accordance with the results of the cluster analysis on a complex of traits we have identified strawberry varieties which are showing the prospect for industrial cultivation. In the new varieties of strawberries as Joly, Vivaldi and Rumba the values of yield and quality of berries are comparable to the best zoned varieties, such as Nelli, Asia and Bogota
The article presents the results of evaluation of 20
strawberry hybrids by breeding in the NCRRIHV on
the traits of productivity and chemical composition of
berries. The results of the grouping of studied hybrids
at the number of berries per plant and average weight
of berries were shown. We have also highlighted the
best hybrids, that shows the maximum number of berries
(pcs per plant) – 2-10-06 Firework × Honey, 5-2-
06 Primella × Marmolada and average weight of berries
(g) - 5-1-12 Elsanta × Alba, 11-7-06 Molling Pandora
× Marmolada, 7-1-12 Elsanta × Camarosa, 6-1-06
Vesnyanka × Primella, 2-4-12 Eros × Camarosa, 3-4-
12 Belrubi × Camarosa. It was found that the integrated
combination of high productivity characteristic values
(the number of berries per plant and average
weight of berries) are not mentioned in any of the hybrid
selections. Study of the traits of berries quality in
strawberry hybrids showed that they contain from 6,3
to 11,4% soluble solids, from 4,8 to 8,6% sugar, from
0,62 to 1,30% acid, the sugar-acid ratio It varies from
4,0 to 8,8 relative units. Almost all the studied hybrids
accumulate in the berries more vitamin C in comparison
with the control variety Honey. According to the
complex biochemical parameters highlighted hybrids
2-9-12 Eros × Camarosa, 2-4-12 Eros × Camarosa, 5-
3-12 Elsanta × Alba, 3-1-12 Belrubi × Camarosa
