Winter Triticale

The aim of the study is to isolate from collection samples of winter triticale the sources of short-stemming and high grain yield for their further involvement in the selection process in the forest-steppe conditions of middle Volga region. The studies were carried out in 2013–2017 on typical gray forest soils. 93 samples of winter triticale of Russian selection, obtained from the collection of All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov. Standard is Bashkir short-stemmed. Weather conditions during the years of study varied significantly. The studied gene pool has a wide genetic diversity in plant height (65 ... 136 cm) and yield (277 ... 579 g/m2). According to the results of analysis of variance, a significant influence of the genotype and year conditions on the manifestation of these characters was established. Plant height and yield depended on both factors and their interaction, but the first trait is determined mainly by the heredity of the varieties (46.1%), and the second - by the growing conditions (61.8%). There was a significant variation in the values of the studied indicators, both by genotypes and by years: the coefficient of intervarietal variation in the average values of the traits of grain yield and plant height for 2013–2017 amounted to 15.0 and 17.2%, respectively, with variation by years 15 , 4 ... 30.7% and 15.1 ... 20.1%, respectively. According to the results of regression analysis, it was found that within the studied gene pool the highest grain yield was formed by samples with a plant height of 86 ... 105 cm. 13 sources of short-stemming with a plant height below 80 cm and 17 high-yielding samples with a yield of 515 ... 579 g/m2 were identified. In these genotypes, the yield excess over Bashkirskaya short-stemmed standard was significant and amounted to 33 ... 97 g/ m2, or 6.8 ... 20.1%. The varieties Tribun, Skif, Kentavr, Sotnik are characterized by the highest breeding value

Phases Of Development

Estimation of spelt wheat and the species of intermediate wheatgrass by the main agrobiological indicators (calendar dates of the beginning of the main phases of plant development, plant height dynamics, dry mass accumulation, grain yield and protein content) compared to soft wheat was done. The index of stability of grain yield formation was determined. It was found that the main phases of development in spelt wheat occurred on average 10–15 days later than in soft wheat. Plants of intermediate wheatgrass in the first year of cultivation had slower growth. The main phases of development in plants of intermediate wheatgrass of the second and third year of growth occurred almost in the same time with soft wheat. It was established that spelt wheat and intermediate wheatgrass were significantly superior to soft wheat in plant height. In the earing phase, the height of these plants was on average more than 100 cm, which had to be taken into account when growing these crops. It varied from 25 to 42 cm in spelt wheat and from 29 to 57 cm in intermediate wheatgrass during the stem elongation phase depending on the weather conditions of the research year. This indicator ranged from 107 to 113 cm and from 96 to 117 cm, respectively, in the earing phase, and from 137 to 168 cm and from 107 to 196 cm in the phase of milk ripeness of grain. Plants of spelt wheat and intermediate wheatgrass had a high stability index of the formation of dry matter and grain yield. It should be noted that intermediate wheatgrass formed a significant vegetative mass even in the earing phase. The vegetative mass in spelt wheat was formed during the earing period – full ripeness of grain. These crops (spelt wheat – 22.1 ± 0.4, intermediate wheatgrass – 22.4–24.6 ± 0.2–0.5) were significantly superior to soft wheat (12.1 ± 0.5) by the content of protein in grain, so it was recommended to involve them in the selection programs to create species with high productivity. However, spelt wheat (5.58 ± 0.13) was less and intermediate wheatgrass (0.98–1.22 ± 0.14–0.18) was the most inferior to soft wheat (8.03 ± 0.27) in terms of grain yield.

The main source of vegetable protein in world production is legumes, including peas (Pisum sativum L.). The creation of new highly productive pea varieties, adapted to local conditions, will solve the problem of food and feed protein. Modern varieties also should be characterized by high homeostaticity and stable productivity in a changing climate. The aim of the study was to study the homeostaticity of pea varieties on the basis of grain yield in the southern forest-steppe of the Republic of Bashkortostan. The studies were conducted on the experimental field of Soil Science, Botany and Plant Breeding Department at the Educational and Scientific Center of Bashkir State Agrarian University in 2009-2018. The soil of the experimental plot is leached chernozem of heavy loam granulometric composition. During the research years weather conditions were contrasting. The object of the study was the following pea varieties: Chishminsky 95, Chishminsky 229, Aksaysky usatuy 55 and in memory of Khangildin. Grain yield was recorded. The overall homeostaticity of the varieties (Hom) was determined. In our studies, the grain productivity of the studied pea varieties varied greatly from year to year. On average, over 10 years, the varieties Chishminsky 229 and a variety in memory of Khangildin were the most productive, and the least productive was Aksaysky usatuy 55 variety. Data analysis showed that the variety has a limiting effect on crop yield resistance to environmental stress factors. Varieties Chishminsky 229 (Hom = 36.6), in memory of Khangildin (Hom = 36.5) were characterized by the highest index of homeostaticity, and the variety Aksaysky usatuy 55 (Hom = 26.5) was the least. The varieties of Chishminsky 229 (Sc = 3.44), in memory of Khangildin (Sc = 3.35) and Chishminsky 95 (Sc = 3.38) possessed the highest breeding value.

One of the effective ways of creating high-yield tobacco varieties is the selection of donors of economically valuable characters and their optimal combination in new plant genotypes. Sources for selection and creation of such donors are gene pool collections, which concentrate source material of different geographical origin with a set of valuable breeding and genetic characters. The level of expression of these characters is modified by breeding conditions and the response of the genotype to environmental factors. Therefore, the main purpose of our research was to study the manifestation of morpho-biological features and properties of plants of tobacco collection samples in agroclimatic conditions of the Central Forest-steppe of Ukraine, establishment of breeding value of available gene pool of culture, selection of sources of economically valuable characters and formation of working tobacco collection. The strategic task of research is to create the varieties that are able to maximize the use of their genetic potential in a specific region, to be resistant to stressful environmental conditions, to ensure a high realization of the genetic potential of productivity. For the first time in the conditions of the Central Forest-steppe of Ukraine the analysis of 30 collection samples of tobacco of different ecological and geographical origin was carried out. New genetic sources for morphological character of plants, raw yield, seed productivity and early maturity, which are used at the Experimental station of tobacco farming National Research Center "Institute of Agriculture of the National Academy of Agrarian Sciences" in variety breeding, were identified. A certificate of registration of the working collection of tobacco gene pool of the present on morphological characters was received from the National Center for Plant Genetic Resources of Ukraine, according to the results of research in 2017–2019 (Certificate № 277 from 29.10.2019).

The results of the study of 250 collection samples of spring soft wheat of various ecological and geographical groups are presented in order to identify the source material that combines optimal plant height and high productivity for the conditions of the forest-steppe zone of the Middle Volga region. The work was carried out in 2017–2020 in the Samara region. The study and evaluation of samples was carried out according to the Methodology of the state variety testing and the methodological recommendations of the VIR. The average height of plants in the samples over the years of research varied within 68.5-109.2 cm, the coefficient of variation of the trait was 11.86-13.72 %. The presence of a positive average and weak correlation between the yield and plant height, regardless of the moisture conditions of the year (r = 0.15-0.47), was revealed. A strong positive relationship was observed between the height of the samples and the following weather factors: precipitation in June (r = 0.94), precipitation during the growing season (r = 0.87), hydrothermal coefficient of June (r = 0.93), hydrothermal coefficient for the growing season (r = 0.83). The highest grain yield was formed by samples from the group of undersized and medium-grown, on average 416 and 428 g/m2, respectively. A number of highly productive varieties were identified: 3 medium-grown samples (105 cm) with a yield of 419.7-435.7 g/m2 and 21 undersized samples (85-102 cm) with an average grain yield of 485.0-585.7 g/m2. Dwarf specimens sample a stable manifestation of short-stemmed growth over the years and high resistance to lodging were noted. According to the research results, it was found that the optimal height of plants for the forest-steppe zone of the Middle Volga region is in the range of 85-105 cm. The selected undersized and medium-grown samples with high grain yield and dwarf samples with high resistance to lodging are recommended for use in breeding programs of the region and places with similar conditions.

The aim of the study is to characterize winter triticale samples by protein content in grain and productivity, to identify sources of high protein content and high grain yield for use in breeding process. Experimental work was carried out in the conditions of Tatarstan Republic in 2013-2017. The collection of 93 varieties of winter triticale of Russian selection, obtained from the Federal Research Center “All-Russian Institute of Plant Genetic Resources"(VIR) was evaluated in field trials. Wide genetic diversity of the studied gene pool was demonstrated by grain protein content (11.69...16.15 %) and grain yield (277...579 g/m2). Protein content and grain yield were mostly determined by the growing conditions – the factor “year” (58.1 % and 61.8 %, respectively), with a relatively small share of the factor “genotype” (23.9 % and 15.4 %, respectively). Significant variation in the values of the studied indicators, both by genotype and by year, was observed. There were identified 19 sources of high protein content in grain (over 14.5 %) and 17 sources of high grain yield (over 510 g/m2), which showed a significant excess of the standard Bashkirskaya korotkostebelnaya. A group of samples with a relatively high protein content (13.8 ... 14.1 %) and yield higher than the average value (450...500 g/m2) was identified. The highest breeding value among the sources of high yield was shown by samples Zimogor, Kornet, Privada, Vodoley, 3/9 oh Ag 4418, and among the sources of high protein content – Kurskaya stepnaya, Mir, Student, Svyatozar. The listed variety samples additionally possessed a complex of positive features: high ear productivity, high full-scale weight and large grains. In varieties Dokuchaevsky 8 and Privada there was noted a favorable combination of significantly high levels of yield (542 and 527 g/m2, respectively) and protein content in the grain (14.28 and 13.93 %, respectively). The finding of a reliable moderate negative correlation (r = -0.682) between yield and grain protein content indicates that grain protein content can be increased by breeding methods at relatively high or medium yields of varieties.
