DescriptionThe researchers of the institute are studying adaptive power of 17 varieties and 6 lines of winter wheat sown after peas using various methods of assessment of their adaptive properties. During the years of study (2012-2014) we found out that environmental conditions which account for 78% have the greatest effect on the trait ‘grain productivity’ in the formation of the yield. The share of genes accounts for 9,7%, the specific correlation ‘geno type x environment’ accounts for 10% which allow calculating adaptive properties. It has been defined that productivity of winter soft wheat changed a lot due to growing conditions and characteristics of varieties. The productivity ranged from 38,7 c/ha (‘Garant’ in 2014) to 76,5 c/ha 9’Lilit’ in 2013). The study found out that the varieties ‘Stanichnaya’, ‘Asket’ and ‘Lilit’ possess the highest response to cultivation with bi=1,15; bi=1,18 and bi=1,25 respectively. The varieties ‘Lilit’, ‘Krasa Dona’, the lines ‘430/07’, ‘260/09’ and 771/09’ possess a high adaptive ability and productivity with 111%, 105%, 108%, 105% and 106% respectively. The study of adaptive properties of winter soft wheat varieties gives an opportunity to distinguish adaptive, stress tolerant varieties with plasticity according to the primary structural elements which form productivity. The varieties ‘Asket’ and ‘Lidiya’ are characterized with high response to cultivation in different environmental conditions. The varieties ‘Lidiya’ and ‘Kapitan’ belong to adaptive cultivars. The varieties ‘Kapitan’, ‘Krasa Dona’ and the line ‘234/07’ are stress tolerant according to the trait ‘grain productivity’; the varieties ‘Kapitan’, ‘Krasa Dona’, ‘Lilit’ and the line ‘771/09’ are stress tolerant according to the trait ‘number of seeds per a ear’; the varieties ‘Lilit’, ‘Krasa Dona’ and the line ‘771/09’ are stress tolerant according to the trait ‘weight of seeds per a ear’

COLLECTION SAMPLES OF SOFT WINTER WHEAT TOLERANT TO LEAF RUST AND POWDERY MILDEW
06.00.00 Agricultural sciences
DescriptionDiseases cause great damage to agriculture, reducing yields and decreasing its quality. The losses are up to 20-30% of potential crop yields. Different types of rust and powdery mildew cause significant damage to wheat. Thereby, the growing of varieties tolerant to these diseases is of great importance at present. It allows solving such problems as the improvement of stability of grain production (especially in the epiphytotic time), improvement of its quality and reduction of prime cost of the product. Cultivation of resistant varieties gives the opportunity to avoid a use of crop protection chemicals and thus, to improve environment. The researches were carried out in the laboratory of intensive soft winter wheat breeding and seed-growing of FSBSI ARRIGC after I.G. Kalinenko in 2013-2015. The crop was sown in a bare fallow. 275 samples of soft winter wheat from the world collection VIR, Turkey (CIMMYT), new varieties of domestic and foreign breeding, varieties and constant selection lines of own selection were the subjects of the study. Favorable for disease development weather conditions allowed evaluating collection samples according to the degree of infection with leaf rust and powdery mildew under natural conditions. According to a complex resistance to leaf rust and powdery mildew we have distinguished the following samples: ‘Nakhodka’, ‘1226/98’, ‘662/99’, ‘1366/08’, ‘Patriarkh’ (Russia); ‘Shestopalivka’(Ukraine); ‘Simonida’ (Serbia); ‘MV 15-04’ (Hungary); ‘Rialto’ (England); ‘Menestrel’ (France); ‘№42 CIMMYT’ (US). Thus, our conducted study resulted in distinguishing the samples of soft winter wheat which are resistant to leaf rust and powdery mildew and are recommended to use as a source of resistance and tolerance to these pathogens. The samples with a combined resistance to both pathogens are of particular interest

06.00.00 Agricultural sciences
DescriptionThe key task of the agriculture in Russia is the further improvement of grain production. Thus, prevention of losses of winter wheat yields because of the diseases remains relevant. The significance of varieties tolerant to diseases, especially to smut (fungus) is of primary importance. Therefore, it’s essential to create initial material for breeding of the varieties tolerant to smut. According to the results of the trials with artificial infection with pathogens, among the samples of winter wheat there have been identified varieties belonging to different groups of tolerance to smut. They are a highly sensitive cultivar ‘к-69361’ (Korea), a sensitive variety ‘Izyuminka’ (Russia), moderately sensitive variety ‘Asket’ (Russia) and almost tolerant variety ‘1621/03’ (Russia). We studied the reaction of the hybrids F2 on infection with smut in different variants of hybridization to obtain stable progeny. The correlation between the number of infected plants in parent and hybrid (F2) populations have been considered. The productive tillering of the plants has been determined in all variants of the trials; it was the least one on the plants with 100% of infected leaves. The hybrids F3 and F 4 have been distributed according to the degree of their tolerance to smut. For further work we have selected the lines with practical resistance to smut (fungus)

DescriptionThe article substantiates a necessity to apply the method of interspecific hybridization in durum winter wheat breeding, using the present soft winter varieties for improvement of frost and drought tolerance at the beginning of germination; resistance to snow mold, fusariosis and bacteriosis of ears and grain. The article presents the results of a comparative study of different types of crossbreeding at interspecific and intraspecific hybridization due to germination, emergence, productivity. It has been shown that intraspecific hybrids ‘T. durum оз. х T. durum оз.’, interspecific hybrids ‘T. durum оз. х Т. аestivum оз’ and ‘Т. аestivum оз. х T. durum оз.’ possessed the highest germination and emergence with 71,8/75,3% for direct and 60,4/82,5% for backward, 42,8 and 35,5% and 55,4 and 64,1% respectively. In backward (triplecross) cross-breeding of F1 interspecific hybrids with durum winter wheat the grain germination was down to 37,4 and 36,6%, but the emergence was up to 64,1 and 69,7% and reached the level of intraspecific hybrids. According to the elements of ear (head) productivity (grain mass per head, number of seeds per head), interspecific double-cross hybrids of the first and the second generation significantly conceded to intraspecific hybrids, but they matched them in a number of spikelets and grain size. The triple-cross hybrids exceed the double interspecific hybrids in this respect, but they concede to double-cross and triple-cross intraspecific hybrids. We studied the principle of splitting of interspecific hybrids of the second generation ‘T. durum оз. х Т. аestivum оз.’ and ‘T. durum оз. х T. durum оз.’ (direct and backward) and the triple-cross hybrids obtained from cross-breeding of interspecific and intraspecific double-cross hybrids F1 with durum winter wheat

DescriptionThe organization of animal feeding in the summer and procurement of fodder for the winter are of great importance. The sowings of sugar sorghum can become a reliable and stable source of fodder even in the regions with insufficient humidity. It is a unique drought tolerant crop, which can be used as green mass, hay, silage, grain, mono fodder, briquettes. The article gives the study results of green mass and absolutely dry substance, and the assessment of cultivation efficiency of such sugar sorghum varieties and hybrids grown in FSBSI ‘I.G. Kalinenko ARRIGC’ as ‘Zernogradsky yantar’, ‘Debyut’, ‘Listvenit’, ‘Zersil F1’, ‘Elisey F1’. The productivity of green mass and dry substance of the new variety ‘Listvenit’ and the hybrid ‘Elisey’ exceeded the standard variety on 7,0-5,0 t/ha and 2,30-0,74 t/ha respectively. The cultivation technologies of sweet sorghum varieties and hybrids produced the high net energy of 69,6-121,9 GJ/ha with the coefficient of energy efficiency of 3,72- 5,08. As for the energy, the cultivation technology of the sweet sorghum hybrid ‘Elisey’ can be considered as the most efficient variant, as it produced the maximum net energy of 121,9 GJ/ha with the coefficient of energy efficiency of 5,08

DescriptionBased on the analysis of the nature of some flowering test crosses which have been resulted in the hybridization with purposely chosen sterile sources (analyzers), the new self - pollinated lines of maize have been identified according to the content of fertility-restorer genes of ‘C’ type of CMS. Genotype of the line RD 257 - rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD 245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V), genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6 (class VI ) genotype of the line RD 261 - Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification of the content of the alleles of fertility - restorer genes allows forecasting the nature of flowering hybrid progeny resulted in the hybridization with a known genotype. We have created a catalog of self - pollinated lines of maize according to the fertilityrestorer genes, which consists of 18 lines, which have been studied in all the years of research. We have identified the lines belonging to classes I, II, III, V, VI, VII and VIII. During the transfer of maize hybrids on a sterile basis the lines of classes I and VIII are those ones which have been of great interest. The self - pollinated lines KV 204, SP 286 (class I) are the reliable fixers of «C» type of CMS. The progeny resulted in the hybridization with any sterile lines is characterized by complete sterility. The new self - pollinated lines KV 498, KV 272, KV 227, SP 357, RD 261 (class VIII) are constant natural fertility-restorers. They are able to fully restore fertility in hybridization with any sterile lines and in any growing conditions

DescriptionThe value of the initial material for selection for heterosis is primarily defined by the combining ability in respect to the main economically valuable characteristics. Combining ability with respect to “grain productivity” has been studied among fourteen selfpollinated lines of maize of early ripening and three testers in the system of hybrid combinations. We have proved that weather conditions have an influence on the variability of the estimates of the combining ability. We have identified the new self-pollinated lines of maize SP 165 and SP 175, which are characterized by invariably high evaluations in the effects of GCA (gi) in different years. The new self-pollinated line SP 167 has got high variants of SCA (δ2si). The new lines SP 161, SP 163, SP 167 and SP 174 have been characterized by the variability of the evaluations in the effects of GCA. They are related to the first or second rank in respect of GCA, depending on the year of the conducted evaluation. These are SP 163, SP 164, SP 170, SP 171 and SP 173 that have differed by their variability of the variants of SCA (from the low variants to the high ones). The highly productive testcross hybrids: Madonna M × SP 165 (4.88 t / ha), Madonna M × SP 171 (4.85 t / ha), Madonna M × SP 167 (4.80 t / ha), T 7M × SP 165 (4.78 t / ha) have been obtained based on the self-pollinated lines having invariably high figures of GCA and SCA

DescriptionThe study was carried out during 2010-2015 years in the All-Russian research Institute of Grain Crops named after I.G. Kalinenko (the laboratory of the cultivation technology of plowing crops), situated in the southern soil-climatic zone of the Rostov region, which is characterized with the unstable and insufficient humidity. The trials were conducted on the heavy loamy, calcareous chernozem obyknovenny (natural blacksoil). The object of the study was the grain sorghum variety ‘Zernogradskoe 53’, approved to use in the Rostov region. The agroclimatic conditions during the years significantly differed during the vegetation in the amount of precipitations (from 110.2 mm in 2010 to 200.2 mm in 2013) and in the temperature regime (from 2512.9 0С in 2010 to 2788.8 ºС in 2015), that allowed evaluating the grain sorghum productivity more objectively. The article gives the study results of the effect of the weather conditions on the duration of vegetation, productivity and grain quality (content of protein, oil, ash and fiber). The article showed the estimated interconnection among the sum of active temperatures, precipitations and hydrothermal coefficient during the sorghum vegetation with the principal economic-valuable traits of grain sorghum. The sum of active temperatures showed the greatest effect on the duration of the vegetation (r=0.89); the sum of precipitations during the vegetation had the greatest effect on the productivity (r=0.80). There was determined the strongest positive correlation of the sum of active temperatures with the content of protein in the grain sorghum kernels (r=0.80) and the average negative correlation with the content of oil (r=-0.69). The sums of active temperatures and precipitations, when the grain sorghum gives the largest productivity, were established

MODERN ASSESSMENT OF NUTRITIONAL VALUE OF SORGHUM FORAGE
06.00.00 Agricultural sciences
DescriptionSorghum is a source of concentrated, succulent and coarse forage. Its grain is used for making the mixed fodder and as the concentrated forage for swine, cows, sheep, horses and poultry. Sweet sorghum is successfully used for silage and haylage. Green chop of Sudan grass is used as fresh food for domestic animals and it’s used for making hay and silage. The nutritional value of the fodder is the way to meet the animal needs in nutrients, necessary for living. To determine the nutritional value of the fodder, oat fodder units and energy fodder units or exchange energy are used. At present the assessment of nutritional value according to fodder units is being revised, because it doesn’t give the true picture of the value of fodder nutrition and animal needs in nutrients. The general energetic nutritional value of fodder is considered as contents of all organic substances, supplied with fodder or with its energy. The nutritional value of fodder is valued according to the characteristics of its chemical composition, digestion of nutrients and general (energetic) nutritional value. The purpose of the work is to assess the nutritional value of fodder, obtained from the best sorghum varieties, as the food for different kinds of agricultural animals. Sorghum, used as fodder for poultry possesses the largest nutritional value. Among the grain sorghum varieties, the variety ‘Zernogradskoe 88’ has got the biggest value of fodder units. The green chop of Sudan grass and green fodder for silage of sweet sorghum possess the greatest nutritional value for swine. The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’ and the variety of sweet sorghum ‘Listvenit’ are the best varieties according to the contents of fodder units
