Improvement Effect

The development of bakery industry is possible due to the use of such non-traditional raw materials as durum wheat. The purpose of the current study was to estimate the effect of varietal traits of durum wheat when mixed with bread wheat according to the results of rheological parameters of dough, technological and bakery estimation of flour. There have been studied technological indicators of grain, rheological and physical parameters of dough, general bakery estimation. There has been established that the high gas-forming ability of durum wheat allows it to be used (30%) as bread wheat improver during baking. However, the positive effect was present not in all years of the study. There has been estimated an improvement effect due to mutual compensation of the missing components and complementarity of the bread and durum wheat varieties. There was found that in 2008, 2010 there was practically no improvement effect when durum wheat flour was added to the mixture in a ratio of 30:70%. There was established that in 2015 the maximum bread volume of 930 cm3 and a good bakery estimation (flat surface, oval shape, golden brown crust, as well as fine thin-walled porosity with elastic light crumb) were obtained by adding bread wheat varieties to durum wheat varieties, which during the year of the study there was formed weak grain (dilute of dough was 110 u.f.; valorigraphic number was 46 u.v.). In 2020, the varieties used in the mixtures of both spring bread and durum wheat were of high quality, and bakery estimation gave excellent indicators both in the control (the variety ‘Tulaykovskaya 108’ with 1300 cm3) and in the mixtures with 1140–1255 cm3; the appearance of bread and crumb in almost all variants had an excellent mark. The largest volume of bread, 1255 cm3, was obtained when the durum wheat variety ‘Bezenchukskaya Niva’ was added to the mixture. Adding durum wheat flour to the mixture in an amount of 30:70% when baking bread reduced its staleness by 6.5% relative to the control (bread wheat); bread remains fresh for a long time with an elastic, quickly regenerated crumb.

Delayed Flowering

During the 2007 winter cropping season in Australia, severe leaf-spotting (necrosis) symptoms resembling chloride (Cl–) deficiency found in North America were reported in the newly released durum wheat variety Jandaroi. Testing for bacterial, fungal and viral pathogens all proved negative. Four Australian durum and four Australian bread wheat varieties were grown, along with a North American variety of each, in a glasshouse experiment using a sterile sand–vermiculite mix and nutrient solutions containing 0 (nil), 0.5, 1.0 or 2.0 mm Cl–. When grown in the nil Cl– solution, all durum and some bread wheat varieties produced leaf-spotting symptoms the same as observed in the field. Nil Cl– also delayed flowering, reduced biomass, decreased grain size, and depressed grain yield in most durum and bread wheat varieties. In field experiments, additions of Cl– fertiliser as KCl at sowing provided no biomass or yield response from a range of wheat varieties, probably because the plants accessed sufficient Cl– from below 0.9 m depth in the soil. Chloride concentrations in whole-plant tissue sampled at head emergence suggested that unfertilised plants were borderline deficient in Cl– according to critical values established in North America. An in-crop foliar Cl– application experiment showed linear uptake of applied Cl–, as MgCl2, until the end of tillering. However, because leaf-spotting symptoms typically appear only after tillering, it is not possible to correct Cl– deficiency by adding Cl– fertiliser to the affected crop after symptoms appear. Managing Cl– in susceptible crops therefore needs to be preventative rather than curative. Among commercial varieties, Jandaroi was highly sensitive to low Cl–, Caparoi was moderately sensitive, and EGA Bellaroi was tolerant. Several elite durum breeding lines grown in 2010 showed considerably reduced leaf spotting compared with Jandaroi under low Cl– conditions, indicating potential for conventional breeding to reduce the potential impact of low Cl– soils on durum production in northern Australia.

High Concern

Soil waterlogging at initial growth stages can cause heavy yield losses of winter cereals. Therefore, the screening for submergence tolerance traits in seeds of commercial varieties is of high concern worldwide. Ten Italian varieties of durum wheat (<em>Triticum durum</em> Desf.), bread wheat (<em>T. aestivum</em> L.) and barley (<em>Hordeum vulgare</em> L.) were investigated for their ability to germinate in submerged conditions and to recover after submergence periods of three to 15 days. Submergence prevented germination and decreased germinability, at rates that increased with duration of submergence. Sensitivity ranked in the order: barley &gt;durum wheat &gt;bread wheat. We related the higher sensitivity of barley to its slower germination and slightly higher leakage of electrolytes, whereas the percentage of abnormal seedlings was lower than in other species. It was less than 4%, compared to less than 15 and 8% in durum wheat and bread wheat, respectively. Wide varietal differences were found in all species. According to variety, after 6-day submergence, germinability ranged from 2 to 42% in barley, from 5 to 80% in durum wheat, and from 30 to 77% in bread wheat. Varieties with more than 40% seed survival were three, six and seven per species, in the same order. The differential submergence sensitivity of varieties indicates a potential to select for waterlogging tolerance within Italian genotypes of winter cereal crops.

The aim of this study was to investigate thermal and rheological properties of selected ancient grain flours and to evaluate rheological properties of mixtures thereof represented by pasta dough and dry pasta. Flours from spelt, einkorn, and emmer ancient wheat varieties were combined with quinoa flour. All these flour sources are considered healthy grains of high bioactive component content. Research results were compared to durum wheat flour or spelt wheat flour systems. Differential scanning calorimeter (DSC) and a rapid visco analyzer (RVA) were used to investigate the phase transition behavior of the flours and pasting characteristics of the flours and dried pasta. Angular frequency sweep experiments and creep and recovery tests of the pasta dough were performed. The main components modifying the pasta dough structure were starch and water. Moreover, the proportion of the individual flours influenced the rheological properties of the dough. The durum wheat dough was characterized by the lowest values of the K′ and K″ parameters of the power law models (24,861 Pa·sn′ and 10,687 Pa·sn″, respectively) and the highest values of the instantaneous (J0) and retardation (J1) compliances (0.453 × 10−4 Pa and 0.644 × 10−4 Pa, respectively). Replacing the spelt wheat flour with the other ancient wheat flours and quinoa flour increased the proportion of elastic properties and decreased values of the J0 and J1 of the pasta dough. Presence of the quinoa flour increased pasting temperature (from 81.4 up to 83.3 °C) and significantly influenced pasting viscosities of the spelt wheat pasta samples. This study indicates a potential for using mixtures of spelt, einkorn, and emmer wheat flours with quinoa flour in the production of innovative pasta dough and pasta products.

Yield Losses

In southeastern Australia, Fusarium crown rot, caused by Fusarium culmorum or F. pseudograminearum, is an increasingly important disease of cereals. Because in-crop control options are limited, it is important for growers to know prior to planting which fields are at risk of yield loss from crown rot. Understanding the relationships between crown rot inoculum and yield loss would assist in assessing the risk of yield loss from crown rot in fields prior to planting. Thirty-five data sets from crown rot management experiments conducted in the states of South Australia and Victoria during the years 2005 to 2010 were examined. Relationships between Fusarium spp. DNA concentrations (inoculum) in soil samples taken prior to planting and disease development and grain yield were evaluated in seasons with contrasting seasonal rainfall. F. culmorum and F. pseudograminearum DNA concentrations in soil prior to planting were found to be positively related to crown rot expression (stem browning and whiteheads) and negatively related to grain yield of durum wheat, bread wheat, and barley. Losses from crown rot were greatest when rainfall during September and October (crop maturation) was below the long-term average. Losses from crown rot were greater in durum wheat than bread wheat and least in barley. Yield losses from F. pseudograminearum were similar to yield losses from F. culmorum. Yield loss patterns were consistent across experiments and between states; therefore, it is reasonable to expect that similar relationships will occur over broad geographic areas. This suggests that quantitative polymerase chain reaction technology and soil sampling could be powerful tools for assessing crown rot inoculum concentrations prior to planting and predicting the risk of yield loss from crown rot wherever this disease is an issue.

Triticum timopheevii (Zhuk.) Zhuk. is noted for its resistance to diseases including leaf and stem rust of wheat. Only one gene (Lr18) for leaf rust resistance has been transferred from T. timopheevii to bread wheat. The objectives of this work were to study the inheritance of leaf rust resistance in five accessions of T. timopheevii and to transfer genes for resistance into durum and bread wheats. A diallel set of crosses was made among five T. timopheevii accessions that gave a fleck infection type with an isolate of leaf rust race CBB. None of the F2 populations of the 10 crosses segregated for resistance, indicating that the five accessions all had at least one gene for resistance in common. Several accessions were crossed and backcrossed twice to durum and to bread wheat. At least three genes for leaf rust resistance were transferred to durum wheat and one to bread wheat. The gene transferred to bread wheat and one of those transferred to durum wheat conditioned good resistance to a set of 10 diverse races of leaf rust. Resistance conditioned by all three genes was dominant in durum wheat but the one gene was recessive in bread wheat. Monosomic analysis of the bread wheat line showed that the gene is on chromosome 1A. It should be useful in breeding for leaf rust resistance in both durum and bread wheat. Key words: Triticum timopheevii, leaf rust resistance, durum wheat, bread wheat

The Middle Volga region is traditionally a production region of high-quality durum wheat. For sustainable grain crop production, a system of durum wheat varieties’ breeding is being developed here. For its diversification there has been developed the new variety ‘Bezenchukskaya Yubileinaya’. The breeding process from hybridization of the variety to its study in the competitive variety testing was carried out in the experimental plots of the Samara Research Institute of Agriculture. The competitive variety testing was carried out in parallel at the Federal Altai Scientific Center of Agrobiotechnology. There was conducted the ecological and geographical study in the KASIB system for 2 years (in 2017 and 2018) in 9 eco-points of various institutions in Russia and Kazakhstan. During the period of the variety development (2004–2020) there were spring and summer droughts, one being very strong and 6 being strong, 2 being strong spring and one strong summer droughts, one moderate spring-summer and one moderate spring drought. In the same period, there was an epiphytotics of various pathogens for 5 years. When studied in the competitive variety testing, there were severe spring-summer droughts in 2016, 2018, 2019; there was an epiphytotics of leaf blotches (fusarium, pyrenophorosis) and stem rust in 2016. The years 2017 and 2020 were favorable for the grain yield formation. The realized productivity of the variety ‘Bezenchukskaya Yubileinaya’ was 6.04 t/ha at FSBSI FANTSA (Altai Research Institute of Agriculture) in 2018. In the competitive variety testing of the Samara Research Institute of Agriculture, the new variety productivity exceeded that of the standard one on 0.25 t/ha for 5 years. According to drought resistance, resistance to leaf rust, the variety had an advantage over the standard one. The variety is resistant (R/MR type of resistance) to leaf blotches, grain and pasta quality is at the standard level. The purpose of the current work was to describe the methods of development, properties and testing traits of the new variety.

The purpose of the current study was to develop a new drought-resistant initial material, adapted to local conditions and spring durum wheat varieties on its basis. Due to the method of intraspecific hybridization and individual selection, there has been developed the spring durum wheat variety ‘Yasenka’ in the F5 hybrid combination obtained from crossing the varieties ‘Lilek x Nikolasha’. The developed variety is short-stemmed, middle maturing, resistant to drought and lodging. Its potential productivity is high, due to the maximum yield of 6.44 tons per hectare obtained in 2017 when sowing after peas. On average, over three years of competitive variety testing (2015–2017), its yield was 6.02 tons per hectare, which is higher than that of the varieties ‘Volnodonskaya’ on 1.08 and ‘Nikolasha’ on 0.40 tons per hectare. There has been found an advantage in terms of productivity over other varieties when sowing at a later date. Grain and pasta quality indicators are high. When evaluating grain according to the international standard ISO 21415-2, the variety ‘Yasenka’ showed a high Gluten Index (94) and a Minolta color index “b” (30), which corre- sponds to the world quality level. Under natural conditions, it is characterized by field resistance to the main leaf fungal diseases. Against the background of artificial infection, there has been established high resistance to head smut, powdery mildew and hard smut, resistance to septoria blotch and brown rust, moderate susceptibility to head blight. The variety has been included into the State List of Breeding Achievements of the Russian Federation since 2018 and it’s protected by the patent of the Russian Federation.

Abstract This study was conducted in Meket District, Amhara National Regional State, in northern Ethiopia. Cross-sectional data collected from 214 randomly selected farm households via a structured interview protocol was used for the study. Double-hurdle model was to identify factors affecting the probability of adoption and intensity of use of improved bread wheat varieties and associated technologies in the study area. The first hurdle of the model suggests number of oxen owned by household, mobile phone ownership, education level of the household head and access to extension services significantly affected the probability of any improved bread wheat variety adoption. The intensity of improved bread wheat variety adoption was significantly associated with ownership of main plots, participation in on-farm demonstrations, perception towards shattering problems of local bread wheat varieties, and annual income of household. The findings of this study highlight the importance of economic(such as number of oxen) and institutional(such as access to extension) factors related to agricultural extension and communication, the participation of farmers in on-farm demonstrations, wealth creation and acknowledging farmers’ perception regarding improved bread wheat variety attributes. Development interventions should strive to target such economic, institutional, and psychological factors to promote wider adoption of improved bread wheat technologies.
