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
In the article, it is shown that stability of the enterprise is a complex concept. For an objective estimation of level of steady economic development, it is offered to use a technique on base of criteria indicators. The technique is tested at the enterprises of Stavropol region
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen

Diffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented
