In order to find compounds that increase sugar beet resistance to the adverse effects of herbicides, a series of naphthalenesulfonamides derivatives have been synthesized. The protective effect of new compounds for the herbicide mixture Betanal, Lontrel and Super Zeleke was studied in field conditions. The effect of pyridylhydrazones on the synthesis of photosynthetic pigments in leaves was investigated. Substances with a high protective effect were found
We present a brief description and analysis of the weather conditions of 2005-2011 in North, Piedmont, and the Kuban Krasnodar fruit zones. In the course of many years of research, the optimal conditions for precipitation of water supply as one of the most im-portant factors in increasing the productivity of agro-phytocenoses in the region
The dynamics of α-, β-amylase and summering amylase activity of single germinating spring barley seed is presented for the first time. It has been shown,
that the environment of seed growth period influences the development of ferments’ activity
The ability of Phomopsis to transmit from affected seeds to plants has been studied in both anamorphic and teleomorphic phases of its development in the year of sowing. The sunflower lesion with Phomopsis affects not only the germination, but also causes the plant disease
To control irrigation erosion, the artificial aggregation of soil by structure-forming materials was proposed in the article. The research was conducted for establishing the impact of the percent content of each fraction on soil cation exchange capacity
As a result of the research conducted there have been distinguished the sources and the donors for the subsequent usage in the selection programmers of stone-fruits assortment improvement
The article covers the stages of evaluation and
selection of new self-pollinated corn lines. The results
of testing of new lines and test crosses were reflected.
Comparative analysis of yield of the best test crosses
was presented. General and specific combining ability
of new lines was calculated. The opportunities of
further usage of new lines in breeding programs and
early maturing hybrids including these lines are
considering. The researches were conducted on the
field of the institution, following the course of
scientific researches of department of selection and
seed management of corn, Federal State Budgetary

During 2012-2015 from the two fissile populations
of rice hybrid Il.14 x Kuboyar and Il.28 x Kuboya
we conducted multidirectional selection of panicles
with low, medium and high number of grains in
them. It was established a different reaction to the
selection of hybrid generations by yield. The lowest
yield was formed at planting grain from small panicles,
intermediate - from the middle panicles and
biggest - from the major panicles. The reaction to
selection decreased with each successive generation.
In the hybrid Il.14 x Kuboyar at positive selection of
the yield increase towards the initial population F2
was in F3 - 10,5%, in the F4 - 3,8% and F5 - 1,9%, at
Il.28 x Kuboyar - respectively 4, 4%, 3.1% and
0.7%. At negative selection in Il.14 x Kuboyar there
was a decrease of yield on 7.7% F3, in F4 on 6.9%
and in F5 on 0.2%. By years of research was not observed
variations in grain yield obtained from the
panicle with an average grainness and generally was
at the level of the original population. At the hybrid
Il.28 x Kuboyar for negative selection of the relative
yield initially decreased on 1.7% in F3, while then for
all kinds of selection to the fifth generation grew up
and different to a lesser extent than the first the hybrid,
although the ranks of the values preserved. The
yield from a fraction of well-grained was 98.4%,
medium grained - 96.5%, low grained - 94.2% of the
initial Kuboyar variety
There were cited the results of the comprehensive assessment of the initial material of tomatoes with the marker signs for the aim of their use in the selection of heterotic hybrids of tomatoes on an open ground in Krasnodar region
The article shows the results of integrated assessment of variety-rootstock combinations of plum on clonal rootstocks and different schemes of landing. We have defined the basic biometric parameters of trees, and specific indicators of productivity, allowing to identify the most optimal variety-stable rootstock combination for the conditions of the Krasnodar region
