The type varieties of strawberry with complex resistance to dominant mycosis, that are qualitatively new source material perspective for use in breeding are selected
The paper presents the results of the evaluation of 8 hybrid pink-flowered forms of strawberry for the some economically valuable traits. Selections 1-28-12, 7-20-12, 6-9-12 (Djeni), 8-24-12, 3-27-12, 8-9-12 were studied from the hybrid combination Belrubi × F1 C-141 and 6-14-12, one form 5-9-15 was studied from the combination Onda × F1 Toscana. The analysis of the variability of breeding samples was carried out by the traits of the productivity and quality of the berry: the number of inflorescences, the number of berries, the weight of the 1st order berry, the average weight of the berry, the density of the pulp of the berry, the content of total soluble solids, the sum of sugars, acidity, sugar-acid index, the content of vitamins C, P and anthocyanins. The aim of this work was to evaluate hybrid pink-flowered forms on the traits of productivity and quality of berry and to identify the best ones for use in home gardening in the North Caucasian region. Programs and methods generally accepted in Russia were used for the research. A comprehensive study of strawberry hybrids by the economically valuable characters was provided the distribution of the studied forms on the groups using the cluster analysis by the Ward's method. With a linkage distance of 62.0 cu/s three groups were distinguished, which included one, two and five hybrid numbers of strawberry, respectively. The selection efficiency of partition into cluster groups of the studied hybrid forms of strawberry in accordance with their genotypically determined mutual affinity was also verified by plotting a graphical distribution of hybrids on the plane of the X and Y coordinate axes. As a result of a comprehensive breeding and genetic assessment of hybrid pink-flowered forms of strawberry by the traits of productivity and quality of berry, the best of them were selected for use in the home gardening in the North Caucasian region: 5-9-15 from the Onda × F1 Toscana combination, as well as 1-28- 12, 7-20-12, 3-27-12 and 8-24-12 from Belrubi×F1 C-141.
