Analysis of the technological qualities of spring wheat grain showed, that high-natural grain can be obtained from the varieties of Orenburg and Samara selection in 75.0% of the years, and the Saratov breeding - 62.5% of years. All studied varieties of spring durum wheat form high-natural grains of 87.5% years. Grain with high glassiness is characteristic to varieties of spring wheat of Samara breeding of 75.0% years and Orenburg and Saratov breeding - 87.5% years. High glassiness grain of spring durum wheat varities of Samara and Saratov breeding constitute 87.5% of the years, and the Orenburg selection of 100% of the years. Grain, which protein content is greater than 14% or more in Orenburg steppe, was formed only by varieties of soft wheat Orenburg breeding and Ukrainian durum wheat breeding in years of 12.5%. Grain, corresponding to 1 class by the content of gluten, in our experiments was obtained from following varieties: soft wheat of Orenburg and Samara selection in 75.0% of the years, and the Saratov - in 62.5% of the years; durum wheat of Orenburg and Samara selection in 25.0% of the years, and Ukrainian - 62.5% years. The investigation of soft wheat varieties form grain of I-III quality group and grade durum wheat - II-III quality group.

Identifying genotypes with a greater ability to absorb nitrogen (N) may be important to reducing N loss in the environment and improving the sustainability of agricultural systems. This study extends the knowledge of variability among wheat genotypes in terms of morphological or physiological root traits, N uptake under conditions of low soil N availability, and in the amount and rapidity of the use of N supplied with fertilizer. Nine genotypes of durum wheat were chosen for their different morpho-phenological characteristics and year of their release. The isotopic tracer 15N was used to measure the fertilizer N uptake efficiency. The results show that durum wheat breeding did not have univocal effects on the characteristics of the root system (weight, length, specific root length, etc.) or N uptake capacity. The differences in N uptake among the studied genotypes when grown in conditions of low N availability appear to be related more to differences in uptake efficiency per unit of weight and length of the root system than to differences in the morphological root traits. The differences among the genotypes in the speed and the ability to take advantage of the greater N availability, determined by N fertilization, appear to a certain extent to be related to the development of the root system and the photosynthesizing area. This study highlights some variability within the species in terms of the development, distribution, and efficiency of the root system, which suggests that there may be sufficient grounds for improving these traits with positive effects in terms of adaptability to difficult environments and resilience to climate change.

AbstractAssessing durum wheat genomic diversity is crucial in a changing environmental particularly in the Mediterranean region where it is largely used to produce pasta. Durum wheat varieties cultivated in Portugal and previously assessed regarding thermotolerance ability were screened for the variability of coding sequences associated with technological traits and repetitive sequences. As expected, reduced variability was observed regarding low molecular weight glutenin subunits (LMW-GS) but a specific LMW-GS allelic form associated with improved pasta-making characteristics was absent in one variety. Contrastingly, molecular markers targeting repetitive elements like microsatellites and retrotransposons – Inter Simple Sequence Repeat (ISSR) and Inter Retrotransposons Amplified Polymorphism (IRAP) – disclosed significant inter and intra-varietal diversity. This high level of polymorphism was revealed by the 20 distinct ISSR/IRAP concatenated profiles observed among the 23 individuals analysed. Interestingly, median joining networks and PCoA analysis grouped individuals of the same variety and clustered varieties accordingly with geographical origin. Globally, this work demonstrates that durum wheat breeding strategies induced selection pressure for some relevant coding sequences while maintaining high levels of genomic variability in non-coding regions enriched in repetitive sequences.

SUMMARYThe possibility of growing dry peas in the semi-arid areas of Mediterranean countries was assessed by comparing dry pea (Pisum sativum L.) varieties with the highest yielding barley and durum wheat varieties under rainfed conditions and with supplementary irrigation in Cyprus. The yield of barley cv. Kantara was greater than that of the best pea variety selected, PS 210713, especially under the driest conditions, but the differences between cereals and dry pea varieties were smaller when grown in areas where there was more rain or where supplementary irrigation was supplied. The protein content of the dry seeds and straw of the peas was higher than those of the cereals. It is concluded that selected varieties of dry peas could be grown in dry Mediterranean areas, particularly in rotation with barley or wheat.Pisum sativum L. para zonas mediterráneas

Seeding Rate

The results of the study of five seeding rates (variants) in the cultivation of spring durum wheat Bezenchukskaya Niva with seed treatment with Scenic Combi preparation (1.4 l/t) in order to identify the optimal rate are presented. On ordinary chernozem for 2017-2020 in the arid conditions of the Volga region, it was found out that when growing a crop for winter wheat, a decrease in seeding rates contributed to an increase in the coefficient of total and productive bushiness, the weight of grain from the ear and plant, the number of grains from the ear. On average, over the years of research, the yield of spring wheat grain at seeding rates of 2.0-5.0 million/ha was 2.00-2.22 t / ha. Under favorable weather conditions, the yield advantage was the norm of 4.0-5.0 million/ha by 6.2-37 %, in the acutely arid 2.0-3.0 million / ha by 3.4-16.4 % more, compared to other options. Wheat yield was most affected by the air temperature during the growing season (r=-0.97* to -0.99*). Of the elements of the structure, the maximum conjugacy with the yield at the norms of 1.0-4.0 is noted with the number and weight of grain from the ear and plant, the height of the plants (r=0,97*-1,0**). On average, over the years of research, the highest net income was established on the variants with the norm of 3.0-4.0 million / ha-17100.4-17442.8 rubles / ha, which is 761.9-1704.7 rubles/ha (4.7-10.8 %) more than the variants with the norm of 2.0 and 5.0 million/ha. The maximum level of profitability was revealed at the rate of 1.0 million / ha-194.6 %, which is 9.6-41.3% more than the options with the rate of 2.0-4.0 million / ha. Based on the conducted research, the seeding rate of 2.0-4.0 million/ha is recommended for the cultivation of spring durum wheat for commercial purposes. In the original seed production – 1.0 and 2.0 million/ha, providing a multiplication factor of up to 57.8 kg/kg of grain.

Aim. To study the selection value of new spring triticale varieties according to the main economic and valuable properties (duration of the growing season, plant height, lodging resistance, resistance to diseases, tillering coefficient, grain weight from one ear, grain yield). Methods. Laboratory, mathematical and statistical, physical. Results. The duration of the growing season of spring triticale was longer compared to wheat. Thus, it was the longest in 2015–122 days, in 2014–112, and in 2013–102 days or 3–9 days more compared to wheat, except for 2014 in which the duration of the growing season of spring wheat was 117 days. This figure did not change depending on the variety of spring triticale over the years of research. The shorter growing season of spring triticale in 2013 was apparently due to the later sowing period. On average, over three years of research, the height of spring triticale plants varied from 99 to 105 cm depending on the variety. Triticale spring exceeded soft spring wheat by 2–8 %. However, Heritage durum wheat plants were the highest. This figure has changed significantly over the years of research. Thus, the highest plants were in the favourable 2014 – 108–129 cm, the shortest in the less favourable 2013 – 85–92 cm, and in 2015 – 100–106 cm. Spring triticale plants had the highest resistance to pathogens of leaf spot in 2015. In 2014, the intensity of their defeat was at the level of 4.0–4.5% with the resistance of 9 points. Triticale spring significantly exceeded the plants of both types of wheat in this respect. On the average for three years of researches, the coefficient of general spring triticale tillering made 1.56–1.65 depending on the variety. This indicator was at the level of durum wheat and 9–14 % lower than that of soft wheat. The productive tillering coefficient was 10–15 % lower than that of soft wheat. Of the five varieties of spring triticale, the highest grain yield was obtained for the cultivation of Kharkiv Oberih variety – 6.12 t/ha. Yields of Kharkiv Lebid, Kharkiv Sontsedar and Kharkiv Korovai varieties were 18–22 % higher compared to soft wheat and 7–11 % higher than durum wheat. Conclusions. Indicators of growth and development of spring triticale plants and grain yield change significantly depending on the variety and weather conditions of the growing season. The duration of the growing seasom of spring triticale is 102–122 days. Plants can be medium and very tall, lodging resistance varies from 5 to 9 points. Triticale spring has a very high resistance to main fungal diseases. Grain yield is 4.93–6.12 t/ha depending on the genotype. To obtain a high and stable grain yield, it is necessary to grow Kharkiv Korovai and Kharkiv Oberih spring triticale varieties.

In the climatic conditions of the Central Black-earth region, the infection of wheat grain with Fusarium fungi is of latent nature and can only be detected by mycological analysis. For this reason, the varietal composition of the pathogenic complex of fungi Fusarium on winter and spring wheat has not been thoroughly studied yet. Working with the problem in the conditions of the Tambov region, it was found that the grain of these varieties was infected with various species of Fusarium. The most infected spring wheat varieties were “Nik” (69%), “Biora” (45%) and “Prokhorovka” (30%). The varieties “Saratovskaya 29” (4%) and “Tulaikovskaya 100” (5%) were less infected than the other. Nine species of fungus Fusarium spp. found on spring wheat seeds were F. acuminatum Ellis, an Everhart (1895), a Wollenweber (1917), F. avenaceum (Corda ex Fries) Saccardo (1886), F. culmorum (WG Smith) Saccardo  (1895), F. equiseti (Corda) Saccardo (1886), F. poae (Peck) Wollenweber in Lewis (1913), F. sambucinum Fuckel (1869), F. semitectum Berkeley and Ravenel in Berkeley (1875), F. sporotrichioides Sherbakoff (1915) and F. tricinctum (Corda) Saccardo (1886). The leading position was occupied by the species Fusarium sporotrichioides and F. avenaceum. The frequency of their occurrence on spring wheat seeds was 56.6 and 20.9%, respectively. The contamination of winter wheat with a Fusarium fungus was lower than the infection of spring wheat (1–8%). Four species of Fusarium spp. were identified on the seeds of winter wheat, they are F. avenaceum (Corda ex Fries) Saccardo (1886), F. graminearum Schwabe (1838), F. poae (Peck) Wollenweber in Lewis (1913) and F. sporotrichioides Sherbakoff (1915). The dominant position belonged to the species Fusarium poae and F. sporotrichioides (41.7 and 37.5%). It has been shown that the level of infection of wheat seeds by Fusarium fungi depends on the variety resistance to the infection.

The Impact

The impact of contrasting conditions of water availability on the size of the upper internodes in wheat varieties was studied under the conditions of the Orenburg steppe zone. It was noted, that less drought-resistant varieties formed a short upper internodes. We conducted a mathematical analysis of the relationship of productivity and length of ear-carrying internodes of spring soft wheat varieties of different ecological groups. It was established, that we can observe a gradual increase of grain productivity with increasing the length of the upper internodes in the studied range. As a result, the following varities were selected for inclusion into the hybridization: Logachevka, Tulaykovskaya steppe, Tulaykovskaya 1, Tulaykovskaya Belozernaya, Prokhorovka and Uchitel. They have the optimal settings for the presented feature. Using the selected varieties as parental forms can enhance the efficiency of wheat breeding programs for resistance to drought in the forest-steppe zone of the Southern Urals.
