At the contaminated by Аmbrosia artemisiifolia fields, a mineral food increase promotes decrease in productivity of sunflower in a greater degree
In the conditions of northern region of Krasnodar region, biological features of ambrosia artemisiifolia and its injuriousness in sunflower sowings were studied in 2006 - 2009
For perfection and enrich on structure of grape on Nakhchivani Autonomous Republic since 1985 has been running researches of agrobiological and technical delineation of new aboriginal, inductions and selection sorts of Vitis vinifera L. In this article the ampelo-descriptoric delineation of two selection technical sorts of grape: Alinja and Uzunsalkhimli is observed. These sorts belong to ecological-geographical group in eastern wine sorts- proles orientalis subpr. caspica Neqr by morphological indication and biological peculiarity. By genetic indication, the sorts of Alinja and Uzunsalkhimli are characterized with very long ( up to 40-50 cm) and big bunch (700-1500gr). Productivity from bush is 10,0 l- 8,0 kg, sugar is 20,2 or 22.0%, sour is 5,4 and 5,7 y/dm3. Selection sort of Alinja is made for preparing high quality red wine of various categories
The report, presented by 18-20.09.2012 in Gaylvaylerhofe / Germany at the European meeting of Ampelography ECPGR in international cooperation of the COST project, provides the information about the collection, the study and the storage of wild grape vines, as well as indigenous and selected varieties in the National ampelographic collections of Russia, nowadays containing 3,220 specimens of 42 countries, 191 of which were oppressed with phylloxera. The modern zoned assortment of grapes in Russia (according to the State register of breeding achievements of the Russian Federation) with the most common areas of local and introduced varieties is examined. The summary of the impact of the clonal selection of the classic industrial engineering classes, conducted by the author’s original technique, as well as the achievements of combinative breeding of the actively breed resistant varieties is given. Moreover, their reproduction at the level of selected protoclones or elite breeding forms (candidate variety) was conducted with in vitro method
The article reflects the results of experimental studies in heterosis breeding of corn. Defined the common (CCA) and specific (SCA) combining ability of the new material. Obtained the valuable inbreeding lines and testers of corn. The prospects are identified for the use of the selected material in heterosis breeding
In the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids
The article gives the analysis of installations using physical factors for seeds presowing treatment, particularly an electromagnetic field. The author has also cited an example of the registered installations for seeds presowing treatment by means of an electromagnetic field
The article presents the analysis of climatic data concerning Michurinsk district of Tambov region, which is necessary for modeling of stressors, on the stage of their maximum values, which will help to increase the precision of selection procedure in fruit crop forms. On the base of the investigation, differences in initial fruit crop forms by their adaptivity and productivity under stressor effect on the level of their maximum values were revealed
In this article, the analysis of thoroughbred sows of breed of Landrace and hybrid sows F1 in a combination (Yorkshire × Lanrace) on reproductive qualities and an index of commodity weight of a nest (ICWN-6) is presented. The economic benefit forecast is resulted at introduction system of hybridization with the use of imported breeds
Duration of vegetation period is one of the main
adaptive traits for any crop or variety. Reasonability
of cultivation of a variety in a particular soil and
climate zone is determined by the duration of the
vegetative period. One of the aims of breeding is
the creation of the varieties with the main vegetative
phases lasting at more favorable climatic conditions.
The most accurate way to determine maturity
group of a variety is by estimation of starting
of heading phase, which can be defined with the
greatest precision. The article covers the analysis of
the duration of the vegetative period of the lines
and varieties of winter barley of local and foreign
selection in the central zone of Krasnodar region.
All the varieties were divided into three maturity
groups. The vegetative periods of the varieties were
studied during four years. The most favorable and
adverse conditions for yield formation were determined.
The interactions between the productivity of
the varieties depending on maturity group were
identified. The varieties of the early maturity group
which are more productive than the check were
selected, which is most valuable for the breeding of
the crop. The best varieties with the high and stable
yield and the positive traits are regularly involved
in the breeding programs with the porpoise of making
new varieties of the winter barley
