Resistance To Fungal Diseases

For breeding to create varieties resistant to fungal diseases, it is effective to work in the search for new genes of resistance to pathogens, as well as to constantly update the gene pool of spring wheat. The researches were conducted in 2014-2019 in the Samara region. The object of study was 352 collection samples of spring soft wheat of various ecological and geographical groups. The assessment of samples for resistance to fungal pathogens was carried out against a natural infectious background, including in years with a strong development of certain diseases (powdery mildew – 2014, brown rust – 2016, 2017). Accounting of plant damage by fungal diseases was carried out according to generally accepted phytopathological methods. Since 2000, the laboratory has studied and developed more than one thousand collection samples, formed working characteristic collections of samples for resistance to leaf rust (142), powdery mildew (185) and with complex resistance to these diseases (100). According to the results of six-year studies, collection samples with complex resistance to leaf rust and powdery mildew were identified: Kinelskaya yubileynaya, Erythrospermum 4112, Erythrospermum 4143, Erythrospermum 4144, Erythrospermum 4146, Erythrospermum 4147, Lutescens 6045/7, Erythrospermum 6310/10-63 (Kinel), Khutoryanka (Tambov), Ulyanovskaya 105, Yaritsa (Ulyanovsk), Tulaykovskaya 108 (Bezenchuk), Sigma 2 (Omsk), KVS Aquilon (Germany). Relatively resistant to root rot pathogens samples were noted: Kinelskaya 2010, Lutescens 3960, Erythrospermum 4112, Erythrospermum 4171, Lutescens 4394 (Kinel). The selected varieties and breeding lines are recommended by us as sources of resistance to fungal diseases for use in breeding programs of the middle Volga region and research sites with similar agro-climatic conditions.

The paper presents data on the evaluation of the effect of ten preparations based on humic substances and silver (FlorhGumat, FloraS, Edagum, Fitop Flora-S, Zerebra agro, BatyrMax, Batyr 40N, Batyr 40N + MAX, Azofoska) on the productivity of spring soft wheat. The productivity of wheat was studied in indicators of: the phase of the plant (according to the scale of Eucarpia) the number of germinal, coleoptile roots, the length of the germinal, coleoptile roots, the number of nodal roots, the length of nodal roots, the summary mass of the roots, the mass of the vegetative part of the plants, the length of the wheat spike, the number of spikelets in the wheat spike, the number of grains in the wheat spike, the mass of the spike, the height of the plants, the area of the flag leaf, the area of the pre-flags leaf, productive tilling capacity, general tilling capacity. Out-root treatment of plants with preparations in appropriate concentrations was carried out in the evening hours during the phases of wheat tillering and the formation of a flags leaf. The greatest influence on the productivity of wheat was provided by the preparation BatyrMax. The preparation Edagum showed maximum effectiveness in the number of reliable positive changes in the productivity of wheat compared to the control (untreated plants) and background (the plants were treated with the preparation Azofoska). Similarities in the action of Edagum, Phytop Flora-S and Zerebra Agro, Batyr 40N + Max on the changes in the most of the wheat productivity indicators were revealed. There was no statistically significant effect on the yield of Flora-S, FlorHumat, Azofoska.

High Quality Seed

One of the leading grain crops in Russia is spring wheat. This is a strategic food crop of our country; it is also an important component in the structure of forage crops for monogastric animals, such as pigs and poultry. The purpose of the research was to evaluate spring soft wheat varieties of different maturity groups in order to identify genotypes as the starting material for obtaining varieties adapted to the cultivation zones, and to determine the areas optimal for the production of grain for seed purposes with high quality indicators. Field studies have been carried out in three ecologically different zones: the Priobskaya zone, the Prialtaiskaya zone, and the Prisalairskaya zone. Under the conditions of the Altai Territory, genetic sources of spring soft wheat have been identifi ed for different soil and climatic parameters of the study zones, the use of which will allow obtaining high-yielding varieties with high quality grain for specific cultivation conditions. The variability of the indicators of the characteristics of varieties in three ecologically different zones has been determined. The indicators of adaptability and stability of spring soft wheat varieties in different zones of cultivation have been determined. The optimal zones for conducting breeding work and seed production of varieties have been identifi ed. New scientific data on the quality parameters of seed grain in various agro-climatic zones of the Altai Territory have been obtained. The share of the contribution of the factors “variety”, “year”, “environment” to the variability of grain quality characteristics has been established. The economic efficiency of cultivating varieties of spring soft wheat for the production of high-quality seed grain has been determined.
