The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
Based on the analysis of 422 samples of compound feeds and grain for processing of different farms of the Krasnodar region, we have established the level of their natural mycotoxin contamination and also identified prevailing combinations. Regularities of the frequency of contamination have been presented as well
Newest wine Muscat grape variety with colored pulp and juice Serra was breeded at Athens Institute of Viticulture (Greece) by P.Zamanidi and L.Troshin in 2007 by crossing the Ukrainian Odessa black variety (Alicante Bouschet x Cabernet Sauvignon) with the new Greek Muscat black berry Krimbas variety. According to the morphological and physiological characteristics it is included in the eco-geographical group of Black Sea Coast. Length of production period is 146-155 days. Strong growth of shoots (2,1-3,0 m). Percentage of productive shoots is over 90. Productivity is very high: 25-30 t / ha. Average weight is 350 g. Grapes characterized with high resistance to cold, drought and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite, with the stamens and fully developed gynoecium. Cluster is medium, conical, sometimes with wing, medium density. Berry is small, round, blue-black, with a thick waxy coating. Peel of medium thickness, dense, durable. Pulp and juice are intensely colored, flavored with Muscat taste. Sugar content is very high, in the bushes at sun-dried bunches up to more than 40%. Prolonged preservation of crop on bushes. Variety is intended for manufacturing intensely colored dry red wines of excellent grade and high-quality sparkling, dessert, sweet and liqueur wines, and is suitable for the manufacture of high quality intensively colored juice with Muscat taste. When used in blends with other varieties increases color, full flavor and improves the bouquet of wine
The development of leaf spot pathogens (yellow leaf spot and septoria spot) has been studied in Belarus and North Caucasian Region of Russia. The resistant wheat cultivars to the pathogens have been revealed
In the conditions of Krasnodar region variety-rootstock combinations of plum Russian in the period of growth and fructification for the purpose of allocation of best of them for use in intensive technologies of cultivation are studied. The most weak, productive, fast-grown variety-rootstock combinations are allocated. They represent the greatest value for use in technologies of intensive type by production of fruits of Russian plum
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
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
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
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

Research Institution of Agriculture
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
