The article presents the results of the influence of the magnitude of heterosis on the main elements of the formation of yield (grain size and productivity of the main spike) of spring wheat in the Irkutsk region. The following were used as maternal varieties: Irgina, Krasnoyarskaya 83, Tulun 15, Tselinnaya 60, Altayskaya 92, Niva 2 and a variety from Mongolia Orkhon 85, as testers - Skala, Angara 86, Tulunskaya 12 The best indicators of hypothetical heterosis were manifested by the number of grains in ear in combinations Krasnoyarskaya 83 × Angara 86, Krasnoyarskaya 83 × Skala, Altai 92 × Skala (81.6 ... 85.7%). In terms of grain weight from the main spike, the best results of hypothetical heterosis were noted in hybrid combinations Krasnoyarskaya 83 × Angara 86, Orkhon 85 × Angara 86, Ni-va × Angara 86, Altai 92 × Angara 86 (100.0 ... 130.7%) ... Krasnoyarskaya 83 × Angara 86, Altai 92 × Angara 86, Or-khon × Angara 86 are recognized as the best hybrid combinations that can give the greatest yield of transgressive forms of elite plants.

Risk Parameters

Irkutsk region is among territories of intense industrial development. Considerable part of the regional population is long exposed to chemical pollutants of environmental objects. Th e authors evaluated carcinogenic risk for the population of industrial centers and rural area. Findings are that maximal carcinogenic risk is carried by the urban population. Aggregated carcinogenic risk parameters evaluation proved inhalation to be a priority route of exposure. Irkutsk region appeared to have territories with high carcinogenic risk for public health. Among a list of chemicals in the ambient air are priority carcinogens: six-valent chromium and lead. The evidences necessitate measures on the risks minimization. Due to absent data on carcinogens content of drinkable water in some rural area, the necessity is to evaluate risk for the rural population by studies of drinkable water quality that does not match hygienic regulations, because oral one is a main route of carcinogens intake.

Semiarid Conditions

The aeolian processes play an important role in the relief formation under the semiarid conditions of the intermountain basins of Southern Siberia. Ancient sand landforms occur in different regions of Siberia — the Ob, Chuya, Аley, Yenisei, Аngara, Selenga, Chikoy, Khilok and Chara river valleys and Lake Baikal coasts. The sandy coasts of Lake Baikal are of great interest in terms of floristic diversity determined by a high degree of endemism. Despite centuries of study of the lake basin, sand vegetation is poorly described in the literature. This study presents an analysis of 184 relevés of psammophytic vegetation from the Republic of Buryatia (Severobaikalsky, Barguzinsky, Pribaikalsky districts) and Irkutsk region (Olkhon Island) obtained in 2009–2014.
