The article proves that the genetic cluster analysis using of parents – offspring system at the period of 38 generations of directional intentional selection to short stem, the height of winter rye plants has been reduced less than 90 cm with simultaneously productivity integral components increasing. Directional selection on parent plants short stem has revealed pleiotropic effects to increasing averages of productivity yield capacity, spike length, flowers number, grains, and short stem and simultaneously its productivity reducing, plant and weight reducing of 100 direct descendants grains. Plant height donor of short stem Gnome 1 has been controlled prevailing by genetic factors and has been less influenced by environmental conditions. Selection by enlargement of elite plants grains has predetermined genetically increasing of the average height of families in the next generation without the concept selection requirements satisfaction. Therefore, the directed selections, by the structural analysis results, are annually held in two phases, first – to the expressed short stem and then among of them – to the high weight of 100 grains per plant and desirable productivity elements. A creative dominant short stem donor with stems up to 90 cm and a weight of 100 grains per plant more than 4.0 g has been made. A short stem spike shortness donor Dwarf 1possesses a significant reserve of common genetic mutation of quantitative characteristics, which can be used by direct and indirect selection. This population has been represented by its large amount, in order to enhance capabilities of directional selection plants short stem providing with the desired productivity components during the studying. Informative additive genetic cluster analysis is high. Plants productivity is considered to be extremely complicated selection characteristics, including many component constituents parts related genetically. One of these traits changing inevitably causes genetic changes in other breeding traits. The aim of the task should be set clearly and information flow should be methodically and genetically corrected used. Keywords: winter rye, the efficiency of selection, inheritance, short stem, Dwarf 1, pleiotropic effects, genotypic, additive correlation.

The article provides progress report on the barley of F3к-10029/Saratovske 4 height decreasing throughout 1974 to 2012 by way of selecting plants of the shortest stem. 38 years of selecting the shortest stem genotypes cut down plant height by 5,7 times at the background of dominant Hl gene expression. Average plant height during 38 breeding cycles was descending by 2,69 cm, but this was not an even trend. New creative donor for ultimate short stem characteristic, Gnome 3, has been developed, with Hl-3Hl-3alleles designation. Relative impact on the efficacy of minus-selection by the plant height of the selection differential (38,00%) and inheritance coefficient in its narrow sense (14,56%) is established. Efficiency of the selection is realized with the decrease of winter rye height plants by 72,08% as expected by the relative breeding forecast. Analyzes is completed for 11 genetic and statistical clusters of average utilitarian characteristics of Gnome 3 ultra short stem rye over the period from 1974 to 2012.

Stabilizing (centripetal) breeding produced donor of short stem characteristic for winter rye (Secale cereale L.) with height of plants ranging from cm 50 to 60. Distribution curve of plant's height remained symmetric with cummulation of frequencies at central classes (leptokurtic). For the first time, designation for new allele of short-stem gene HI-2HI-2 and donor name Gnome 2 was suggested. Gnome 2 was found to have direct genetic correlation of plant height with number of flowers in the ear, length of the ear, weight of 100 seeds from the plant, as well as reverse correlation with ear density and weight of kernels from the ear.

The article presents the estimation of economic and biological characteristics of indeterminant tomato hyb­ rids (Raisa F1, Macarena F1, Emotion F1, Anabel F1, Mariachi F1) under conditions of winter hydroponic. The earliest emergence of fruits is established for Macarena F1 tomato hydrid. The total number of brushes, flo­ ers and w fruits formed on the plant during the vegetation period, is determined. The degree of fruit inception, yield per plant and average weight of the plant are measured. The monthly dynamics of hybrid tomato crops is presented. The largest harvest was collected through May to July. Marketable and non-marketable portions of the harvest and commercial quality of tomato fruits are determined. A close correlation between fruit weight and fruit yield is established. The Macarena F1 hybrid is distinguished as the most precocious and high-yielding variety.

A stabilizing (directed) selection has created a donor of short stem for winter rye (Secale cereale L.), plant height of which ranged from 50 to 60 cm. The plant height kept symmetry of its distribution curve and the frequency accumulation in central classes (positive excess). For the first time a symbolic designation to new short-stem related Hl-2Hl-2 allele and the donor name (Gnome 2) were proposed. 28 years of stabilizing selection showed that 57% of overall genetic variability of plant height resulted from adaptive genes available for directed selection by phenotype, and 43% from dominant and epistatic factors that predetermines the expression heterosis effect. Gnome 2 donor proved to have genetic additive correlation between the pants height and number of flows per ear, ear length, weight of seeds per plant , 100 seeds weight per plant; to have reverse correlation with ear density seeds weight per ear. The height of original parent components have displayed direct additive correlation with number of flowers per ear and reverse with the ear density. The additive correlation component directly exposes «genuine» impact of parental plants on the expression of the characteristics indicated among the offspring Productive bushing of parental plants, seed weight per plant directly, and seed size (100 seeds weight) indirectly, respectively, influence the height of offspring pants. The reverse additive correlation between the parents height and 100 seeds weight in the offspring is caused by pleiotropic effect of the genes impact thus enabling to combine the desirable characteristics in one genotype. Productive bushing is by 54% due to the impact of general genetic factors among the above, in particular, 30% due to that additive, 24 due to non-additive factors. The concept of genetic improvements for productive bushing of the Gnome 2 rye implies utilization of additive effect through the directed selection, as well as application of breeding techniques for controlling the effect of heterosis caused by the genes of dominant and epistatic impact. The selection paradigm requires simultaneous genotypes selection with immediate examination of the selection results by offspring while in parallel to develop inbred lines, combining these afterwards evaluating general and specific combining ability by productive bushing. It is also to be noted that the productive bushing essentially depends on the environmental conditions, which significantly corrects the implementation of productivity potent, thereby the issue of agronomical conditions aimed at extending the expression of characteristic in question remains.

Outlook for selection on increased photosynthetic productivity of winter rye plants is discussed. Donors of short-stem resistant to powdery mildew winter rye were bred with erect and drooping shape of leaf blade. In the erect form the apexes of leaf are oriented at the angle drooping form has 45° inrelation to the stem. Incomplete domination of the drooping leaf shape with ratio 1 : 2 : 1 is established. For the first time symbolic designation of dominating genes is offered with drooping leaf blade - StSt, with transitional heterozygote Stst with recessional heterozygote stst. Higher yield of grain in the comparative variety examination was proved to be received for the erect leaf form, which is predetermined by decrease of plant height, increase of kernel weight from ear, as well as of 100 kernels from plant and by quantity of redicles. Drooping leaf blade rye forms are also promising for selection on increased photosynthetic potential.
