Abstract Background Mungbean (Vigna radiata (L.) R. Wilczek, or green gram) is important tropical and sub-tropical legume and a rich source of dietary protein and micronutrients. In this study we employ GWAS to examine the genetic basis of variation in several important traits in mungbean, using the mini-core collection established by the World Vegetable Center, which includes 296 accessions that represent the major market classes. This collection has been grown in a common field plot in southern European part of Russia in 2018. Results We used 5041 SNPs in 293 accessions that passed strict filtering for genetic diversity, linkage disequilibrium, population structure and GWAS analysis. Polymorphisms were distributed among all chromosomes, but with variable density. Linkage disequilibrium decayed in approximately 105 kb. Four distinct subgroups were identified within 293 accessions with 70% of accessions attributed to one of the four populations. By performing GWAS on the mini-core collection we have found several loci significantly associated with two important agronomical traits. Four SNPs associated with possibility of maturation in Kuban territory of Southern Russia in 2018 were identified within a region of strong linkage which contains genes encoding zinc finger A20 and an AN1 domain stress-associated protein. Conclusions The core collection of mungbean established by the World Vegetable Center is a valuable resource for mungbean breeding. The collection has been grown in southern European part of Russia in 2018 under incidental stresses caused by abnormally hot weather and different photoperiod. We have found several loci significantly associated with color of hypocotyl and possibility of maturation under these stressful conditions. SNPs associated with possibility of maturation localize to a region on chromosome 2 with strong linkage, in which genes encoding zinc finger A20 and AN1 domain stress associated protein (SAP) are located. Phenotyping of WorldVeg collection for maturation traits in temperate climatic locations is important as phenology remains a critical breeding target for mungbean. As demand rises for mungbean, production in temperate regions with shorter growing seasons becomes crucial to keep up with needs. Uncovering SNPs for phenology traits will speed breeding efforts.

The article is devoted to the study of the state and trends of the publishing activity of Ukrainian scientists and leading countries in the field of life sciences («Life sciences»). The Web of Science Core Collection (WoS CC), Journal Citation Report (JSR) and InCites, as well as classifications of scientific fields designed to structure the publication flow of scientific papers and journals in these information resources, are used for the research base – Web of Science Categories and Research Areas. The article presents the results of the author’s research on the publication indices of scientists of Ukraine and the leading countries of the world for the period 2008-2018 in the field of “Life Sciences” according to the international science-computer database of Web of Science. Conclusions about the growth of indicators of publication activity of scientific works in the field of “Life Sciences” are made. The tendency of a significant increase in their number in Ukraine has been revealed, but domestic studies do not represent all the areas of «Life Sciences» most popular in foreign scientists
