The breed of grape of Hrisi Irini is bred in Greece by P.Zamanidi and L.Troshin in 2003 by mating of the Greek breed of Asirtiko with the French breed of Semilon. Duration of production period is 156-165 days. Growth of shoots is strong (2,1-3,0). Degree of ripening of a vine is very high. Productivity is high. Average mass of clusters is 200 Differs with high winter hardiness, drought resistance and the raised resistance to fungous diseases in comparison with breeds of Vitis vinifera L. Flower is bisexual. Cluster is average, cyclo-conical, average density. Berry is average, oval, greenish-yellow colour, with a dense bloom. A pellicle is dense. Pulp and juice with high-quality odour. Sugar content is very high, it reaches 40 % with constant acidity in air-dry clusters on bushes. The breed of Hrisi Irini is included in ecological and geographical group of breeds of basin of Black sea under its morpho-physiological characteristics. The breed is intended for manufacturing dry white wines of an excellent class, and also high-quality dessert, sweet and sparkling wines; it is applicable for production of high-quality juice, compotes as well. The breed is very perspective for southern zones where grapes have no sufficient acidity
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 newest wine white-berry fruitful high-grade breed of grape - Pontos is bred in Greece P.Zamanidi and L.Troshin in 2003 by mating of the Greek breed of Sideritis with a breed of Sovignon. Duration of productivity phase is 156-165 days. A breed is tall. A degree of vines ripening is very high. Productivity is very high, 15-16 t/hectares and more. The medial mass of racemations is 390 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds Vitis vinifera. A flower is bisexual. Racemations are big, pencil-point, with medial denseness. Baccas are average, circular, greenish-yellow color, with a dense wax coating. A peel is tight. Pulp and juice with the expressed high quality flavor. Sugar content is high. It dries when over-ripening and stays on bushes. Under morpho-physiological characteristics, it is included in ecological-geographical bunch of breeds of basin of Black sea. The breed is designed for production of dry white wines of the excellent class, and also high-grade sparkling wines; it is applicable for production of high-grade juice and compotes as well
