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

Peach (Prunus persica) is an economically important temperate fruit crop due to its edible fruits. Due to the need to develop new varieties better adapted to climate change, it is of great interest to find germplasm adapted to warmer conditions, such as those found in the Canary Islands. Peach was an important crop during the last century in one of those islands (La Palma), but its cultivation has been abandoned in recent years. Currently, commercial production is relict and isolated trees are relegated to family orchards with little management. With the objective to characterize and prevent the loss of local varieties of this crop, peach trees were sampled along La Palma. A total of 89 local peach accessions were prospected and analyzed with 10 single-sequence repeat (SSR) loci, which permitted 28 different genotype profiles to be detected. These genotypes were compared to 95 Spanish peach landraces conserved in an ex situ collection, and 26 additional samples from eight different countries. Results showed that the peach genetic diversity found in La Palma was low. In addition, a relation between La Palma samples and other Spanish peaches was observed, which could indicate the arrival of genetic material from the Iberian Peninsula and subsequent intercrossing and local selection of the genotypes more adapted to the subtropical climate of the island. The population structure reflects a grouping of the samples based on fruit type and geographic origin.
