А. В. Смиков | О. С. Федорова | Ж. Е. Сучкова
The article mentions that 113 peach hybrid forms resistance to drought, to leaf curl infection Taphrina deformans Tul. and powdery mildew Sphaerotheca pannosa Lev. var. persicae Woronich have been obtained in the result of their studying. One of the most important agronomic sigh is a drought- resistance. Elite forms assessment on this indicator has been carried out in the most drought year during the last50 years. 23 forms with high drought-resistance have been selected. The leaves curl and false mildew are considered to be the most harmful fungal diseases reducing the plants peach vitality and leading to their lethality. Infection assessment has been carried out according to the average annual dates, and in epidemic (epiphytotic) year with a maximum disease revealing. As a result 14 hybrid forms infected by low leaves curl and 16 – by false mildew have been selected. According to the varieties characteristics complex 15 ones have been selected. Most varieties identified by their drought-resistance have belonged to the North Chinese eco-geographic group (59,1%), by a low leaves curl infection (Taphrina deformans Tul. ) to the Iranian eco-geographic group (64,3%); by the false mildew (Sphaerotheca pannosa Lev. ) to the Northern Chinese eco-geographic group (54,3%). The selected varieties perform the interest as sources of important mentioned economic valuated characteristics and they can be used in breeding.

2013
В. В. Скорик
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.

В. Б. Кутовенко | Н. С. Гаврилюк
The article highlights potential features for the varieties of vegetable bean and actual losses of yield subject to the total amount of photosynthetically active radiation (PAR) received over the vegetation period in the Forest-Steppe of Ukraine. It is established that the potential of the vegetable bean yield in Ukraine depends on PAR received over the vegetation period. All the varieties had their yield upon receiving PAR higher by 0,26-0,41 t / ha compared to that of control. Potential yield of vegetable bean varieties when PAR is used by 2% amounted to 57.25–59.30 t / ha, which was 2.2–3.6 times more than their actual yield. The smallest actual yield loss compared to that potential was inherent in the varieties of Bartoli and Windsor (2.2–2.3 times). The actual yield losses for Karadag and Karestyno varieties were the highest, namely 3.6 times higher compared to the potential prospect.

Influence of varietal characteristics and growth factors on the quality of Natsional’na and Polis’ka 90 winter wheat varieties was studded. Grain of Polis’ka 90 variety was distinguished by considerable variability of grades, however, the grain of Natsional’na variety was exposed to greater number of growth factors. Grain unit index influenced the grain quality grade of Natsional’na 90 determination, gluten quality and protein and fiber content indices influenced that of Polis’ka 90. It was established that the grain of Polis’ka variety in most of the cases had higher grades of quality than Natsional’na variety. The highest grades of quality were registered for the seed harvested after perennial grasses, namely 2d and 3d grades of Natsional’na variety and the 1t and the 2d for Polis’ka 90 variety. Greater grades of quality were registered for the seed grown according to intensive and ecological farming systems (generally, grades 1 to 3), while the lower grades were inherent to biological system (generally, grades 3 to 5).

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.
