IDENTIFICATION OF SEEDS DIVERSITY IN SUGAR BEET HYBRIDS AND LINES

Abstract

Background: Seeds diversity manifests in their heterogeneity according to morphological characteristics and sowing qualities, depending on the genotype and growing conditions. One of the main indicators of the different qualities of beet seeds is the germinative energy and germination capacity, which depend on the genotype. The influence of agrotechnical factors on the diversity of seeds exceeds genetic. Aim: The purpose of the study is to identify the effects of the pre-sowing treatment of the inorganic chemical compound on the diversity of sugar beet (Beta vulgaris L.) seeds for lines and hybrids. Methods: As the signs of the seeds diversity is understood, germinative energy, seedling length, seedling mass. It is presented a method for identifying the genetic diversity of seeds of hybrids and lines of Beta vulgaris, including the treatment of seeds with an aqueous solution of the inorganic chemical substance at a concentration of 10 % with an exposure of 15 s, calculation of criteria for the diversity of seeds: germinative energy, seedling length, seedling mass. Results and Discussion: It was used high concentrations of the inorganic chemical compound for revealing the genetic diversity of seeds. Reactions of genotypes of sugar beet on the provocative factor (the inorganic chemical substance) were different from each other. The inorganic chemical compound is used as a provocative factor and agrotechnical method, and the characteristics of seedling length and seedling mass are taken into account as indicators of the heterogeneity of hybrids and lines in the early stages of plant development. Conclusions: The study allows to reveal the genetic diversity of sugar beet seeds according to the criteria "germination energy" and to assess the heterogeneity of hybrids and lines at early stages of plant development according to the characteristics of seedling length, and seedling mass
