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
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
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
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
At the contaminated by Аmbrosia artemisiifolia fields, a mineral food increase promotes decrease in productivity of sunflower in a greater degree
Chemical and amino acid composition of bare-grained barley was studied. Use of bare-grained barley as a component of compound feeds for young pigs favors the increase of live weight, decrease of food conversion rate and increase of economic efficiency
Nitrogen supply of soils is an important factor in the successful cultivation of agricultural crops. Nowadays, in the Central Black Earth region there are planted orchards with high density of trees, with installed systems of drip irrigation and fertigation. Such orchards are relatively new, particularly in this region. Fertigation ambiguous effects on soil structure and its content of nutrients, especially hydrolysable nitrogen. Therefore, the study of the distribution of hydrolysable nitrogen in the soil under the influence of fertigation and drip irrigation is important. The aim of our research was to investigate the distribution hydrolysable nitrogen in the root soil layers 0-20, 21-40, 41-60, 61-80 cm. Investigations were carried out according to conventional methods. In these layers of the soil, we have determined the content of hydrolysable nitrogen and yield. As a result, we have found that in variants with fertigation were the highest yield. In addition, with fertigation it was noted higher content of hydrolysable nitrogen in the soil as compared with the control without irrigation, especially in the deep layers 21-40; 41-60 and 61-80 cm. It was also noted increase of hydrolysable nitrogen in the soil along the periphery of the wetting
The article presents the data of the degree of allelopa-thy-optical activity of extracts from the aerial parts, roots and rhizosphere of weeds, which is manifested in the inhibition of germination of winter wheat. Rusty-negative balances of cockle and wild oats, containing cellulose and decomposing slower, depress the test-culture of winter wheat after mineralization within 30 days
The article provides an overview of the results of the research of non-root treatment of bushes with activated water with the features of BAS. We have found that activated water, charged with the "Akvator" device through the BAS matrix has the property of impact on plant and the efficiency exceeds impact of BAS solutions themselves
This article presents the results of studies of the effect of different cultivation technologies of winter wheat on the content nutrition elements in the soil
