Winter Wheat Varieties

There are now a rich variety of genomic and genotypic resources available to wheat researchers and breeders. However, the generation of high-quality and field-relevant phenotyping data which is required to capture the complexities of gene x environment interactions remains a major bottleneck. Historical datasets from national variety performance trials (NVPT) provide sufficient dimensions, in terms of numbers of years and locations, to examine phenotypic trends and study gene x environment interactions. Using NVPT for winter wheat varieties grown in the UK between 2002 – 2017, we examined temporal trends for eight traits related to yield, adaptation, and grain quality performance. We show a non-stationary linear trend for yield, grain protein content, HFN and days to ripening. Our data also show high environmental stability for yield, grain protein content and specific weight in UK winter wheat varieties and high environmental sensitivity for Hagberg Falling Number. Using the historical NVPT data in a genome-wide association analysis, we uncovered a significant marker-trait association peak on wheat chromosome 6A spanning the NAM-A1 gene that have been previously associated with early senescence. Together our results show the value of utilizing the data routinely collected during variety evaluation process for examining breeding progress and the genetic architecture of important traits.

Penza region is characterized by a diversity of natural and climatic zones and considerable variability of meteorological factors over the years. Therefore, the creation of high-yielding winter soft wheat varieties with high protein content in grain is one of the most significant challenges in this crop breeding. The purposes of this research are twofold: assess the ability of winter wheat varieties to form high-protein grain in various environmental conditions and isolate a valuable source material for breeding. The research objective is to evaluate winter wheat varieties by such indicator as “mass fraction of protein in grain”. The research was carried out from 2008 to 2017 in a forest-steppe zone of the Penza region. The soils of the experimental field – medium-humus medium-thick leached chernozem with the 35–40 cm depth of the plowing horizon. Ninety varieties of winter wheat from the world collection were the material for the research. The forecrop is black fallow. Square of experimental fields is 3 m2, triple replication. Seeding rate – 5.5 million germinating grains/ha. Standard – winter soft wheat variety ‘Fotinya’. Mass fraction of protein in grain in early ripening and mid-early varieties of winter wheat significantly differed from those of the mid-maturing group. Winter wheat varieties from the mid-ripening group were distinguished by a high protein content (on average 15.5 %), high yield (on average 3.8 t/ha), high yield of protein per hectare (on average 0.59 t/ha). According to the level of stress resistance, varieties ‘Fotinya’ and ‘Moskovskaya 39’ stood out (0.7 and 0.6, respectively). The following varieties are characterized by high genetic flexibility (15.3–16.2): ‘Fotinya’ (Penza region), ‘Moskovskaya 39’ (Moscow region), ‘Bezenchukskaya 380’ (Samara region), ‘Badulinka’ (Volgograd region), ‘Ershovskaya 25’ (Saratov region), ‘Zimorodok’, ‘Pobeda 50’ (Krasnodar Territory), ‘Zernogradka 8’, ‘Konkurent’ (Rostov Region). All the aforementioned varieties have less variability of a characteristic over the years (coefficient of variation – 3.2–9.7 %) and are recommended for use as a starting material for creating new forms.

Marked Tendency

SummaryWinter wheat varieties of contrasting height were grown in a series of yield trials to investigate their response to nitrogen fertilizer. The treatments also included application of fungicides and the use of nets to prevent lodging. The varieties were ‘semidwarfs’ based on the Norin 10 genetic factor Rht2 or taller ‘conventional’ varieties, all well adapted to the U.K. environment. The average response of the semi-dwarf varieties was similar to the conventional and there were varietal differences within each group. There was a marked tendency for the newer varieties to be more responsive but the varietal differences were not consistent between trials, the occurrence of powdery mildew (Erysiphe graminis) being a major factor. When this disease was prevalent, response to nitrogen was greatest in resistant varieties and increased by application of fungicides. In farm practice the optimum rate of nitrogen application for a variety will depend on its physiological response, resistance to lodging and resistance to diseases if these are not controlled by fungicides. No evidence was obtained that the gene Rht2 necessarily confers a greater response to nitrogen.

We analysed five parameters (moisture-, protein content, Hagberg’s falling number, wet gluten content and alveographic W (10-4 J) values) and the microbiological changes of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) during storage, to determine the tendency, type and volume of the of the change of this five qualitative parameters during storage.We found that the examined winter wheat varieties retained their moisture, protein content and their Hagberg’s falling number, they did not change during storage.A slight growth could be experienced in the values of wet gluten content for all the four winter wheat varieties in terms of the duration of storage (129 days). This result proved the theory of after-ripening, when gluten percentage improves qualitatively and quantitatively as well. The value of the quantitative growth was about 10% for all the four winter wheat varieties.We placed a special emphasis on measuring the alveographic W (10-4 J) values during storage. All the four winter wheat varieties showed decreasing values of about 20-40%.Microbiological examinations on the four winter wheat varieties showed that mould, mould flora and total germ count remained balanced with some slight variations and they did not change in terms of time under optimal storage conditions.

Our data also show high environmental stability for yield, grain protein content and specific weight in UK winter wheat varieties and high environmental sensitivity for Hagberg Falling Number. We also show that UK varieties released within this period cluster into four main population groups. Using the historical NVPT data in a genome-wide association analysis, we uncovered a significant marker-trait association peak on wheat chromosome 6A spanning the NAM-A1 gene that have been previously associated with early senescence. Together our results show the value of utilizing the data routinely collected during national variety evaluation process for examining breeding progress and the genetic architecture of important traits.

Winter Wheat Varieties

Owing to the significant differences in the adaptability of state-registered varieties, those which can adapt well to the local conditions should be given preference. There are several high-yielding varieties available in Hungary with excellent agronomic properties, good adaptability and satisfactory baking quality. This study was conducted to analyse the adaptability of 34 state-registered winter wheat varieties tested in the small plot trials of the National Institute for Agricultural Quality Control (NIAQC) at 5–9 locations between 1994 and 1997 based on their gluten quantity and farinographic index. For the comparison of the varieties the evaluation method of Eberhart and Russell (1966) was applied as modified by Bedő and Balla (1977). The qualitative stability and adaptability values of the varieties differ from the adaptability and stability values calculated from the grain yields. Some winter wheat varieties have good qualitative adaptability and stability, while others have special adaptability and poor qualitative stability, but the majority of the varieties do not belong to these groups.
