The spring wheat belt of Western Siberia and Northern Kazakhstan covers more than 15 million ha. While moisture stress is the main factor limiting production, rusts also represent a major challenge, especially in years with higher rainfall. Stem rust was not considered economically important until 2015 when a local epidemic occurred in the Omsk region of Russia and neighboring areas of Kazakhstan and affected more than 1 million ha. It occurred again in 2016 though the spread, severity and losses were less. This study used 16 pathotypes and 17 molecular markers to characterize a set of 146 spring wheat varieties and breeding lines identified as stem rust resistant in Kenya and the Kazakhstan–Siberia region for the presence of major genes. The genetic basis of resistance in the material was limited to Sr25, Sr31, Sr36, Sr6Ai, Sr6Ai#2, and some unknown major genes. Genes Sr25 and Sr6Ai#2 also provided high levels of resistance to leaf rust through linkages with Lr19 and Lr6Ai#2. Adult plant resistance to stem rust was observed in 26 genotypes (16.5 %), including eight possessing Sr57 gene. The high risk of stem rust—as indicated by the 2015 Siberian epidemic—means that there is an urgent need to diversify the genetic bases of resistance and to promote resistant varieties with farmers. © 2016 Springer Science+Business Media Dordrecht

Leaf rust represents the major threat to wheat production in Russia and Ukraine. It has been present for many years and epidemics of the pathogen occur in different regions on both winter and spring wheat. In some regions there is evidence of more frequent epidemics, probably due to higher precipitation as a result of climate change. There is evidence that the virulence of the leaf rust population in Ukraine and European Russia and on winter wheat and spring wheat is similar. The pathogen population structure in Western Siberia is also similar to the European part, although there are some significant differences based on the genes employed in different regions. Ukrainian wheat breeders mostly rely on major resistance genes from wide crosses and have succeeded in developing resistant varieties. The North Caucasus winter wheat breeding programs apply the strategy of deploying varieties with different types of resistance and genes. This approach resulted in decreased leaf rust incidence in the region. Genes Lr23 and Lr19 deployed in spring wheat in the Volga region were rapidly overcome by the pathogen. There are continuing efforts to incorporate resistance from wild species. The first spring wheat leaf rust resistant varieties released in Western Siberia possessed gene LrTR which protected the crop for 10-15 years, but was eventually broken in 2007. Slow rusting is being utilized in several breeding programs in Russia and Ukraine, but has not become a major strategy. © 2010 Springer Science+Business Media B.V.

This article defines the possibilities of using the cluster approach in vegetable and potato cultivation, by forming vegetable micro-clusters, which, unlike the ones used today, require the formation of a favorable institutional environment for innovative development of the industry. It has been substantiated that cluster development of vegetable and potato cultivation is the basis of sustainable development of rural territories, resolving the social and economic problems and development of local self-government. The main role in stabilizing the business sector belongs to the infrastructure support in the market of the region. © Oksana viktorovna shumakova, 2016.

The distribution of stomatocysts of chrysophyte algae in the plankton of bodies of water of different types in the basin of the middle reach of the Irtysh (at the Omsk Region), as well as in the plankton and in fouling of the deep-water oligotrophic lake Teletskoe (Gorny Altai) has been considered. The classification of morphotypes of stomatocysts has been carried out. The number of morphotypes found in plankton samples from bodies of water of the middle Irtysh basin is 30 and, in Lake Teletskoe, 60. Four similar morphotypes of cysts were revealed for the bodies of water under investigation. © 2012 Pleiades Publishing, Ltd.

The mass vegetation of the cyanobacteria Spirulina fusiformis Woronich. was discovered during examination of the shallow Lake Solenoye, situated in the territory of Omsk. Large resources of the raw spirulina biomass in summer make it possible to use the lake as a source of valuable raw material. © 2012 Pleiades Publishing, Ltd.
