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.

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

It is explained the essence of the formation of seed production of lettuce Lactuca sativa var. secalina L. depending on the form of the inflorescence habitus, which formed during the different areas of plant nutrition. It is substantiated the mechanism of seed formation on different parts of the inflorescence of female plant with identification of it’s sowing quality. It is developed the agrotehnologcal measures aimed at improving the productivity of lettuce seed by overcoming its matrical heteroquality

As a result of the lead long-term selection works wint involving a World' s collection and intertype and intertype hybridization with purposeful selection on economic-biological attributes highly productive • grades of a winter wheat, with stability to various kinds of illnesses and high technological qualities of grain have been allocated. The adapted grades of a winter wheat for a various environment of various zones of the countries of the Central Asia that allows to realize potential opportunities of grades in different environments of cultivation and by that to prevent losses of a crop from biotic and abiotic stresses that allows to stabilize productivity and adaptability of culture in a zon winter husbandry are created. The long-term field experiences lead by us and laboratory analyses on a level of productivity, qualities of grain and stability to stresses allows to conclude, that alongside with a genotype, stabilityenvironmental conditions render strong and significant influence on all complex of selection attributes.

The author has estimated the effect of the cultivar-rootstock interaction peculiarities on the parameters of the apple winter cvs ‘Ascol`da’ and ‘Spartan’ on the IS series rootstocks. Dwarf and semi – dwarf combinations have been selected which are the most favourable for the establishment of this crop high – densed orchards in the Lisosteppe of Ukraine.

Three synthetics of Winter Rye were being observed for the quantity of seminal roots (QSR) to study their inheritance. High inheritance coefficients in a restricted sense were established. Genetic improvement of the Rye may be a result of direct breeding and of using heterosis effect. QSR expressed essentially negative genetic correlation with plant height, positive with grain size, productive bushiness and weight of grain in the ear of successors, as well as with grain yield per unit of the area. Genetic correlation coefficients shall be used in the applied breeding.
