The article provides progress report on the barley of F3к-10029/Saratovske 4 height decreasing throughout 1974 to 2012 by way of selecting plants of the shortest stem. 38 years of selecting the shortest stem genotypes cut down plant height by 5,7 times at the background of dominant Hl gene expression. Average plant height during 38 breeding cycles was descending by 2,69 cm, but this was not an even trend. New creative donor for ultimate short stem characteristic, Gnome 3, has been developed, with Hl-3Hl-3alleles designation. Relative impact on the efficacy of minus-selection by the plant height of the selection differential (38,00%) and inheritance coefficient in its narrow sense (14,56%) is established. Efficiency of the selection is realized with the decrease of winter rye height plants by 72,08% as expected by the relative breeding forecast. Analyzes is completed for 11 genetic and statistical clusters of average utilitarian characteristics of Gnome 3 ultra short stem rye over the period from 1974 to 2012.

The trend for development and spreading of diseases and pests of blackcurrant at Orel region in the conditions of extreme drought in 2010 has been detected. Abnormal weather conditions of the summer and the lack of precipitation limited both growth of host plant and disease spreading. At the background of extreme conditions of 2010 the crop phenophases shifted to earlier dates. The awakening of wintering pathogen structures began in the classic dates of the spring, although in summer their biological cycle went off rapidly. Due to the lack of moisture the disease pathogens failed to fully realize their potential of development and spreading. A favorable aspect of the extreme conditions of vegetation period, the reducing of the protective measures against diseases, is to be admitted. Abnormal weather conditions accelerated the pathogen biological cycles and reduced the stock of wintering infection; meanwhile they provoked colonization of the plants by pests. In extremely high air temperature and lasting lack of precipitation the pests number was intensively increasing, exceeding the maliciousness threshold. Due to the above some additional insecticide and acaricide treatments of berry crops were applied. Thus, the vegetation period of 2010 was described as most favorable for the development and spreading of pests and less favorable for disease pathogens.
