The article presents results of the six-year study of the
effect of stocks Riparia × Rupestris 101-14 and Berlandieri
× Riparia Kober 5BB on yield, quality of
grapes and Aligote wine in the central zone of the
Krasnodar region. Effect of stock on scion strongly
depends on the annual weather conditions. In a given
year, there is a stock better adapted to the weather
conditions. Stocks of Riparia × Rupestris 101-14 increase
winter hardiness, and the stock Berlandieri ×
Riparia Kober 5BB - drought-resistant varieties of
Aligote. On average, during six years the stock has not
been resulted in significant differences between the
percentages of developed into shoots buds and fertile
shoots shown in the coefficients of fruiting and fruitbearing
shoots of Aligote. Among all the influencing
factors, the degree of influence of stocks on the percentage
of buds have evolved to 16,4 %, by the percentage
of productive shoots 19,8 %, a factor of the
fruiting shoots and fruitfulness of 3,9 % and 2,7 %,
respectively. Some differences in forming of generative
organs of wintering buds along the fruiting twig
under the influence of stocks do not lead to the significant
difference in biological terms of fruiting varieties
in the whole piece. On average, six years of significant
differences in the influence of rootstocks on the number
of berries in bunches, hundred berries weight, an
average weight of bunches and yield is not defined -
the degree of influence of stocks on mentioned indicators
is 0,1-9,7 %. A significant impact of stocks on the
dynamics of sugar accumulation in berries has not
been discovered. The degree of influence of stocks
onto the final sugar content and acidity of berries is
2.9 and 1.0%, respectively. The wine produced from
Aligote berries on a stock Riparia × Rupestris 101-14
has the better tasting score than on the stock Berlandieri
× Riparia Kober 5BB (7.9 and 7.8 points, respect
vely). The main influence on fruiting of the variety
Aligote was provided by the conditions of the current
and previous vegetation. Within the conditions of the
central zone of the Krasnodar region the cultivating of
the variety of Aligote is reasonable for both studied
stocks
The influence of peach-tree stocks on growth and development of different varieties in the conditions of Krymsk ESS (Krymsk) was studied. There were assessed the different parameters of growth and development of fruit trees. The most effective combinations of this culture were selected by the complex of economic signs
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches of agriculture, economics of agricultural enterprises in whole as well. In article the method of calculation of sufficient balance soil is considered.
The heterosis and inheritance coefficient research results among the first and the second generation hybrids which have been got from the linear and synthetic varieties of winter soft crossing are discussed in this article
The detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability
This article reviews hybrid analysis data on monogenic and digenic patterns of quantitative traits: plant height, panicle length and total number of spikelets
In this work we examine the type of inheritance, number and force of the genes participating in determination of a quantitative attributes of length, width of grain, weight of 1000 grains at hybrids from crossing of the Iranian variety of rice Ambarbu with varieties of Virazh and Boyarin. It is established, that distinctions between samples of length of grain made 3 pairs of genes, of width of grain – 1 pair genes, of weight of 1000 grains – 2-3 pairs genes
The results of the analysis of inheritance of a sign «weight of 1000 seeds» in F1 winter barley are resulted in this article. Examples of various types of inheritance at double-row, correct six-row and wrong (tetrahedral) hybrids are resulted
Biometrical analysis of parents’ forms and hybrids F1 is accomplished; inheritance types of 4-seed beans and 1000 seeds’ mass are established. A degree of domination and value of heterosis and GСA and SCA is determined as well
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
