Classification of plant genepool collections are presented, the principal tasks worked on by collections are examined. Databases on genepool collections of the Institute of Cytology and Genetics of Syberian Branch of Russian Academy of Sciences (Russia) and the National Centre for Plant Genetic Resources of Ukraine are described. Principles of formation of genepool collections, their existing problems, the methods of maintenance of their viability and genetical authenticity are discussed. Necessary amount of collection accessions, differences and specificity of their reproduction and multiplication aims and tasks are proved. Gradations of the permissible changes of accessions in connection with the type and the purpose of collections are proposed. The necessity of specialized periodical edition on genepool collecting is emphasized.

Flowering time synchronizes reproductive development with favorable environmental conditions to optimize yield. Improved understanding of the genetic control of flowering will help optimize varietal adaptation to future agricultural systems under climate change. Here, we investigate the genetic basis of flowering time in winter wheat (Triticum aestivum L.

Article Synopsis
- Genetic diversity is essential for improving taro, a key crop for nutrition and economy in Nigeria, where current yields are low due to limited genetic enhancement.
- A study assessed the genetic diversity of 490 taro cultivars from Nigeria using advanced DArT-SNP markers, revealing greater diversity among Eddoes compared to Dasheens and notable intermixing of cultivars across different states.
- The research found that both phenotypic and molecular methods indicated significant variation, with low correlation between the two assessments, highlighting the need to use both approaches for a comprehensive understanding of taro genetic diversity.

The use of plant genetic resources (PGR)-wild relatives, landraces, and isolated breeding gene pools-has had substantial impacts on wheat breeding for resistance to biotic and abiotic stresses, while increasing nutritional value, end-use quality, and grain yield. In the Global South, post-Green Revolution genetic yield gains are generally achieved with minimal additional inputs. As a result, production has increased, and millions of hectares of natural ecosystems have been spared.

Eggplant (Solanum melongena) is a major vegetable crop with great potential for genetic improvement owing to its large and mostly untapped genetic diversity. It is closely related to over 500 species of Solanum subgenus Leptostemonum that belong to its primary, secondary, and tertiary genepools and exhibit a wide range of characteristics useful for eggplant breeding, including traits adaptive to climate change. Germplasm banks worldwide hold more than 19 000 accessions of eggplant and related species, most of which have yet to be evaluated.

The comparison of closely related taxa is cornerstone in biology, as understanding mechanisms leading up to differentiation in relation to extant shared characters are powerful tools in interpreting the evolutionary process. Hotspots of biodiversity such as the west-Mediterranean, where many lineages meet are ideal grounds to study these processes. We set to explore the interesting example of Sooty Copper butterflies: widespread Eurasian Lycaena tityrus (Poda, 1761) comes into contact in Iberia with closely related and local endemic, L.
