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

Wild Beet

As the major source of sugar in moderate climates, sugar-producing beets (Beta vulgaris subsp. vulgaris) have a high economic value. However, the low genetic diversity within cultivated beets requires introduction of new traits, for example to increase their tolerance and resistance attributes - traits that often reside in the crop wild relatives. For this, genetic information of wild beet relatives and their phylogenetic placements to each other are crucial. To answer this need, we sequenced and assembled the complete plastome sequences from a broad species spectrum across the beet genera Beta and Patellifolia, both embedded in the Betoideae (order Caryophyllales). This pan-plastome dataset was then used to determine the wild beet phylogeny in high-resolution. We sequenced the plastomes of 18 closely related accessions representing 11 species of the Betoideae subfamily and provide high-quality plastome assemblies which represent an important resource for further studies of beet wild relatives and the diverse plant order Caryophyllales. Their assembly sizes range from 149,723 bp (Beta vulgaris subsp. vulgaris) to 152,816 bp (Beta nana), with most variability in the intergenic sequences. Combining plastome-derived phylogenies with read-based treatments based on mitochondrial information, we were able to suggest a unified and highly confident phylogenetic placement of the investigated Betoideae species. Our results show that the genus Beta can be divided into the two clearly separated sections Beta and Corollinae. Our analysis confirms the affiliation of B. nana with the other Corollinae species, and we argue against a separate placement in the Nanae section. Within the Patellifolia genus, the two diploid species Patellifolia procumbens and Patellifolia webbiana are, regarding the plastome sequences, genetically more similar to each other than to the tetraploid Patellifolia patellaris. Nevertheless, all three Patellifolia species are clearly separated. In conclusion, our wild beet plastome assemblies represent a new resource to understand the molecular base of the beet germplasm. Despite large differences on the phenotypic level, our pan-plastome dataset is highly conserved. For the first time in beets, our whole plastome sequences overcome the low sequence variation in individual genes and provide the molecular backbone for highly resolved beet phylogenomics. Hence, our plastome sequencing strategy can also guide genomic approaches to unravel other closely related taxa.
