In the article, the results of the genetic analysis of inhe-ritance of hybrids F2 are presented. Degree and fre-quency of transgression are calculated
The introgression of race-specific blast resistance genes Pi-ta, Pi-b, Pi-z into genotype of Russian rice variety has been performed by backcross method with marker control of donor alleles. Plants that demonstrated maximal similarity with recurrent parental form, the short vegetation period and abundant panicle fertility have been picked up from BC3-population.
Marker analysis of developed population revealed the samples carrying introduced target genes in homozygote state
Progress of molecular genetic developed different types of DNA-markers, which are founded on analysis of DNA-polymorphism. Using of these markers has hanged methods of genetic diversity estimation as well as plant cultivars passportisation and classification
The article deals with the modelling of the ecological soil fertility in two types of soil (alluvial-meadows and dark brown soils) under vegetable soils which had been constructed in the Autonomous Republic of Nakhchivan. In the content of the work the ecological conditionus which effects the model soils, physico- chemical properties and capability had been analuzed, the ecological soil fertility modelling in two tupes of soil of the Autonomous Republic had been constructed.As a rezult, the theoretical and practical significance of the ecological fertility modelling which had been constructed in two types of under vegetable soils in the Autonomous Republic of Nakhchivan
The stages of forming a unified system of planting in Volzhskiy are reviewed. Economic mechanism for implementing the proposed activities is statedм
The differences of phenotypes of perspective varieties of the apple-trees of Pinova and Honey Crisp and peculiarities of passing the main phenological phases of growth and development, relation to draught, amount and quality of crop yield with the regard to tree stock and conditions of growing were revealed in this research
The article presents the results of studies on the species composition of fungi isolated from seedlings of grapes affected by vascular necrosis
The history of department of genetic, breeding and seed-growing is linked to development of Kuban Agricultural Institute. The role of V.S. Pustovoit – the first chief of department, a famous breeder of sun-flower is shown
The changing dynamics of nutrients in soil, doses of mineral fertilizers, efficiency, a mode of onion irrigation on irrigated soils of Rostov region are resulted in the article
The "Academician Trubilin" breed of grape with the colored pulp and juice is bred in Greece by P.Zamanidi, L.Troshin and L.Maltabar in 2003 by mating of the Greek breed of Armeletusa with French Alikant Bush. Duration of rule-oriented phase is 146-155 days. Productivity is high. The medial mass of racemations is 170 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds of Vitis vinifera L. Flower is bisexual. A racemation is medial, cylindrical with a wing, medial denseness. Bacca is small, roundish, blue-black color, with a dense wax coating. Peel is tight. Pulp and juice are intensely colored, with high quality tang. Sugar content is high. Differs with long preservation of crop on bushes. The breed is designed for production of intensely colored dry red wines of the excellent class, and also for high-grade dessert and sweet wines; it is applicable for making high-grade juice as well
