CORRELATION AMONG QUANTITATIVE TRAITS OF SORGHUM GRAIN
06.00.00 Agricultural sciences
DescriptionAt present, the farmers have to develop varieties and hybrids, which fully meet the requirements of agricultural production. The study of correlation among economic-valuable characteristics of grain sorghum is of great importance nowadays, as it allows optimizing plant-breeding work at its early stages. For a more productive process of developing of the initial material in breeding, it is necessary to determine the correlation among the traits to identify the strongest connections, and to conduct further work, based on the obtained data. Knowing the correlation, the estimation of timeconsuming economic trait can be replaced by the assessment of the simpler trait correlated with it. The article presents the analysis of correlation among various traits of grain sorghum. The degree and direction of the correlation have been estimated. The significant effect of the length of vegetation period on many traits has been seen. There have been also mentioned the characteristics, having an influence on a size and a number of kernels per panicle. There is a positive correlation between a size of panicle and dimensions of a leaf (length, width). Along with it there has been found a positive correlation among linier dimensions of a panicle, length and width of a leaf, a number of leaves with a number of kernels per panicle. While studying the correlation between an extension of a panicle with other traits, there has been noted a negative correlation between a length of vegetation period, length and width of a leaf, but there has been found a positive correlation with plant height. There has been found a positive effect of 1000-kernel weight, a number of kernels per panicle, a number of leaves and their dimensions on the formation of kernel weight per panicle

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

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

06.01.05 Selection and seed production of agricultural plants (agricultural sciences)
DescriptionThe purpose of the work was to test the winter wheat varieties artificially infected with North-Caucasus brown rust to identify its harmfulness. There was carried out a two-stage testing on two sets (8 and 10) of varieties that differed in their resistance to the pathogen. As a result, there has been identified high brown rust harmfulness in susceptible varieties, which led to a yield decrease from 16.3 to 32.2%. Among the maximum infected varieties, there has been identified the most tolerant variety ‘Tarasovskaya 29’ which, when damaged to 100%, had a minimum yield decrease (less than 10.6%). The poorly susceptible to brown rust varieties reduced their yields from 11.2% to 20.7%. Among them, the variety ‘Spartak’ showed lower rates of a yield decline. Among the five varieties that showed an average brown rust affection, there have been noted various indicators of a yield decrease. The variety ‘Donskaya Yubileynaya’ showed a minimum decrease of a yield and its structural elements under the conditions of artificial infection with brown rust; and together with the variety ‘Tarasovskaya 29’ can be classed to the varieties tolerant to brown rust. When predicting brown rust epiphytoty the susceptible and medium-resistant wheat varieties require obligatory protection with fungicides

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
