Kupriyanova T. The Morphometric features of variety and interspecific hybrids of potato and their influence on the process of products

Object: a productive process in different manifestation of the ripeness and cultivars and interspecific hybrids of potato. Aim: To determine the effect on the productive process is the possibility of varieties of interspecific hybrids to form shoots, stems, establishing the dynamics of accumulation of crop varieties and hybrids, a manifestation of morphometric parameters and to establish links between them and productivity, taking into account the external environment. Methods: Field (registration and up) - to determine the morphometric, agronomic performance, phenological data of the material used in the research; laboratory (process) - to determine prorostaniya varieties and hybrids, statistics - to determine the correlation between the manifestation of symptoms, defining a significant difference between varieties , hybrids of them. Results: Bulbo forming ability capacity of waste forms, such as factor productivity and the relationship between recent levels, and five of its components. Established only by the high correlation coefficients between the number of large tuber sprouts and the number of stems, tubers, and a mass of commodity production. The influence of biological characteristics of cultivars, interspecific hybrids and conditions of the vegetation period at the beginning of bulbo forming ability, the date at which the curves rise phytomass of plants and weight of tubers. The nature of the growth of above-ground parts of plants, in particular, leaves, depending on the specificity of the material, the external environment. Established mutual influence of biological characteristics of cultivars, interspecific hybrids and external conditions on the rate of accumulation of the crop. Established specificity of the manifestation of the static metric and allometric morphometric parameters depending on the particular environmental conditions years of the experiment, the material (for different maturity varieties, interspecific hybrids) and its performance. Revealed a significant effect on the correlation between productivity and morphometric parameters of biological characteristics of cultivars, interspecific hybrids, the conditions during vegetation, assessed the performance of the material.New ness: first time in Ukraine conducted the original study to determine the ability of cultivars, interspecific hybrids of potato to form large, small shoots, stems from them, and additionally formed. Sphere of introduction:Breeding institutions.
