Assessment has been carried out for parental lines and hybrid combinations of forage beet by individual indices of productivity and morphological characteristics of root storages. Best combinations have been selected for further crossing and breeding.

The results of investigation of pigmental complex and anatomical structure of red currant leaves in connection with the drought resistance are given. The genotypes of red currant: «Gazel», «Belka», «Jonker van Tets», «Viksne», «Selyanochka», «Niva», «Gollandskaya krasnaya», «1432-29-98» and «1426-21-80» have more xeromorphic structure of leaves, providing of ecological tolerance to drought and high temperature. Varieties «Roza», «Dana» have a low adaptation to drought resistance.

Development and improvement of a female component of MS hybrids of sugar beet were carried out on the basis of the following methods: inereasing frequency of occurrence of sterility maintainers by means of preliminary saturation of the population with alleles of the x and z genes; the use, as a female form, of simple sterile hybrids from the crossing of sterile lines with unrelated O-types; and also the drawing in of complexes of valuable genes from materials of foreign origin.

Purpose. Creation of experimental sugar beet hybrid combinations of high sugar yield values and defining gene­tic determination of their heterotic effect. Methods. Diallel crossing and topcrossing, genetic analysis of quantitative traits. Results. The authors have studied the frequency of occurrence of sugar beet heterotic hybrid combinations for «sugar yield» trait created on the basis of two pollinator lines to be genetically valuable for productivity elements, CMS lines and single-cross sterile hybrids with the use of diallel and topcrossing system of controlled hybridization. The share of parental components’ effect and their interaction in CMS hybrids variability for productivity was determined. Expediency of heterotic forecasting based on high combining ability lines was substabtiated. Promising high-yielding sugar beet combinations were selected that exceeded the group standard by 4.1–16.3%. Conclusions. The theory of genetic balance by M. V. Turbin was confirmed. Such hybrids as [CMS 5OT 4]MGP 1 (116.3%), [CMS 1OT 2]MGP 1 (112.5%) and [CMS 3OT 5]MGP 1 (113.2%) were recognized as the best for their productivity, MGP 1 and MGP 2 lines – as the best for their combining ability.

The article considers the results of studying breeding material of sugar beet (MS-lines and many-seeded pollinators) of Ivanivsk Variety Testing Station in the framework of Beta-Intercross Program. Betaintercross Breeding Program for Sugar Beet has been developed by, and is implemented in, the Institute for Bioenergy Crops, formerly known as Sugar Beets Institute (ISB). Ivansivsk Variety Testing Station has been fully engaged into implementation of the Program since 1996. Key task for the Program is to draw genetic potential of breeding materials of sugar beet of the Institute research entities, namely Bila Tserkva Breeding Research Station, Ivanivsk Breeding Research Station, Uladovo-Liulinets Breeding Research Station, Uman Breeding Research Station, Ialtushkivka Breeding Research Station, as well as domestic and foreign companies with the view of maximizing the effect of heterosis use with the view of producing highly productive hybrids of new generation. Over various years, apart from various experimental re-search entities of the Institute, such companies as KWS (Germany), Novi Sad Institute (Serbia), Ramon (Russia), Danisco Seed (Denmark), Belorus ZDS and others have taken part [in the above Program]. The article provides key principles for the Program implementation scheme and its method. The cooperation has enabled to produce a range of highly productive hybrids listed in the State Register capable of competing at today’s market of sugar beet seed. Among these there are hybrids produced jointly with Ivanivsk Research Breeding Station, in particular: Romul (2005), Prometei (2008), Ramses (2009), Risolt (2007), Kvarta (2010), Zluka (2010), ITSB 0801 (2011), ITSB 0802 (2011), ITSB 0904 (2012), ITSB 0905 (2012).

Capitalistic relations were contributing to origination of research breeding during the second half of ХІХ Century. Breeding and seed companied were starting to emerge in Europe in the middle of ХІХ Century. Most famous among them were Velmoren, Depre, Turner (France), Rabbetge and Gizeke (Kleinvantsleben), Dippe und Shriber (Germany) and other.

The conditions for creating active collection of genetic material of sugar beets and coffee chicory by using the method of temperature limitations for in vitro culture are defined. It is proved that the temperature rate in culture rooms at 10 degrees Celsius ensures storing of sugar beets for ten months and chicory for eight months without transplanting.

The features of sugar beet polygerm seed populations were studied. The ways of creation of combinationaluable pollenizers line –– component hybrid on sterile base were improve. The environment conditions had influenced on reaction of different types of genic interactions in specific sets of hybrids. The positive effects of interaction is a part of heterosis effects. It is proved that plasticity and stability effect depend on environment condition where genotype realization occurs.

Molecular selection (MAS) makes the newest trend in breeding that has been progressively applied in many agricultural crops, including sugar beet. The article reviews papers on sugar beet MAL in Russia and overseas consi­ ering the methods applied and results obtained, das well as prospects for further development of this trend.

Evaluation of the genetic component values considered to be the important part of the selection process on creating hybrids of sugar beet and The aim of the study is to determine tetraploid pollinators combining ability Bilotserkovskoy breeding on yield and sugar content and the genetic determination of the productivity elements and their phenotypic manifestations in first generation hybrids of sugar beet. The methods of test crossing on the type top cross of pollen sterile lines of Uuladivsky and Ivanovsky origin and stabilized ployidnistyu tetraploid pollinators of beet sugar Belotserkovskoy selection on yielding of sugar beet tetraploid pollinators of Bilotserkovskoy breeding have been applied. A key role belongs to non additive gene effects in gene structure of characteristics variability yielding has been determined.The part of additive gene action pollinators is predominant in genetic control of top cross hybrids sugar content. The 16 hybrid combinations are differentiated by their parental components combining ability. Pollinators of 1007 (the yield) and 1013 (for the sugar content) have been characterized by their valuable additive gene complexes. Perspective hybrid combinations for their further breeding study are revealed, genetic determination of productivity elements and sugar yield is defined Analysis of gene interactions in sugar beet hybrids confirms the theory of genetic balance MV Turbine
