In the trade of the European Union principally the analysis of alveographical and extensographical parameters mean the acceptance system.In the present study we analysed the extensographical parameters of 10 winter wheat varieties breed by the Cereal Research Non Profit Company with Brabender extensigraph and we made a comparison, correlation among the results. The examinations with Brabender the following among: show the GK Kalász and the GK Élet varieties show high resistance of extension and the GK Petur variety produces high extensibility. The GK Garaboly has shown low extensibility and energy. The other parameters had different values in the examined three years. The measurings with SMS2 Texture Analyser show middle positive correlation between extensibility and subarea. There are weak correlation between at the significantial level in the 90, 135 resistence of extension by Brabender and by SMS2 Texture Analyser and in the 45 extensibility by Brabender and by SMS2 Texture Analyser of relaxed dough. There is no correlation among other parameters.

The gluten examination test is dominant in Hungary, comparing it to the qualification system of other countries. The determination of alveographic parameters is a basic criterion of winter wheat specifications in some western and southern European countries.In the Hungarian and foreign winter wheat qualification systems, in the standards, there is no limit for extensographical parameters. Customers dictate the limits and make their claims as to the specifications.We analyzed the alveographic and extensographical parameters of 19 winter wheat varieties grown by the Cereal Research Non-Profit Company in Hungary, and we made a comparison between the results in the challenges of the European Union expectations.Examining the information of alveographic and extensographical values, we found that the experimental varieties provide high base to flour types suitable for baking bread and baker’s ware. The GK Élet, GK Petur, GK Memento, GK Csillag, GK Kapos and GK Marcel varieties can meet the market of paste flour needs, too.In the variety series, the GK Kalász represents the highest values and the GK Garaboly shows the lowest parameters regarding the alveographic W and the resistance to extension.On the basis of relation, we can establish that we can estimate the following little known and used quality indexes: the extensographical resistance to extension with extensographical energy and the alveographic W value, the extensographical energy with the alveographic W value and the alveographic P and L values with the other alveographic parameters.

Nowadays, many methods have been worked up in the interests of objective expression of winter wheat rheological quality. These define wide spectrum in view of their complexity and apparatus claim. The needs for the methods are definitely increasing in Hungary, too. It is very important to get acquainted with the alveographical quality and qualification and also their using in wide range.In our research we examined the alveographical parameters of 12 winter wheat varieties in Szeged (in Hungary) on the basis of the results in three years (2005-2007).We established with correlation analysis that there is no statistical relation between the alveaographical W and G values. The other alveographical parameters have significant correlation.

Winter Wheat Varieties

New varieties of soft winter wheat have been submitted for state scientific and technical expertise: Krasunya Poliska, Mokosha, Pyriatynka, Fortetsia Poliska, Efektna – in 2018, Zemlerob and Lyubito – in 2020. The best varieties in 2020 were Efektna – 6.87 t/ha, Pyriatynka and Zemlerob – 6.56 t/ha each, Fortetsia Poliska – 6.48 t/ha. During 2016-2020, all the varieties undergoing qualification examination exceeded the Lisova pisnia standard in terms of yield (5.97 t/ha). Thus, the yield of the Fortetsia Poliska variety was 7.31 t/ha, Pyriatynka – 7.10 t/ha, Zemlerob – 7.06 t/ha, Krasunya Poliska – 6.95 t/ha, Lyubito – 6.72 t/ha ha, Efektna – 6.36 t/ha, Mokosha – 6.27 t/ha. It is worth noting the significant variation in the yield over the years of research in all varieties submitted for further study and registration for state scientific and technical examination. At the Panfil research station, the yield of soft winter wheat varieties Mokosha and Zemlerob exceeded the standard in terms of yield – 6.4 t/ha, Fortetsia Poliska – 6.1 t/ha and the Efektna variety was not inferior to the standard – 5.9 t/ha. Brown rust damage during 2016–2020 was lower compared to powdery mildew. It was found that the Efektna variety had a very high resistance to both powdery mildew and brown rust. Very high resistance to brown rust was observed in 2020 for all varieties that were submitted for variety testing. It was found that the incidence of leaf septoria during 2016–2020 was high compared to brown rust and powdery mildew. The cultivar Zemlerob was selected, which had both a stable lesion (Min = 7 %) and a weak susceptibility (Max = 28 %). It was found that in the snowless 2020 and in the abundant rainfall of 2018, the defeat of septoria leaves had moderate resistance (X = 15.81 %) and (X = 20.03 %). Studies have shown that in 2020 a very high resistance to septoria of the ear was observed in the variety Fortetsia Poliska. In the Pyriatynka, Efektna, Lyubito varieties, the development of the disease was noted to be 1.0 % and the spread of the disease in the area – 10.0 %. Key words: soft winter wheat, variety, variability, yield, resistance to diseases, powdery mildew, brown rust, leaf septoria, olive mold, striped mosaic of leaves, BYDV.

Resistance of 31 winter wheat varieties (bred in 6 European countries) to Fusarium head blight (FHB) was evaluated in field trials lasting for three years (2007, 2008, 2009) after artificial inoculation with Fusarium culmorum. The data on deoxynivalenol (DON) content were supplemented by symptom scores and determination of % of Fusarium damaged grains and % reductions of thousand-grain weight and grain weight per spike due to infection. These varieties and also 120 advanced breeding lines from the Úhřetice Breeding Station, SELGEN company were examined for the presence of gibberellic acid (GA) insensitive semi-dwarfing genes to evaluate their effect on FHB. The conditions of experimental years highly influenced the performance of all characters. The highest production of DON occurred in 2008 at a high temperature and high moisture content during the infection period. In all years the moderate resistance to accumulation of DON (at the level of Swiss variety Arina) was detected in the Czech varieties Bakfis, Federer, Baletka, Samanta and Sakura. Among these varieties, Federer showed a low accumulation of DON at a relatively higher symptom expression and greater reduction of grain weight per spike, but the other four varieties and the reference variety Arina expressed resistance in all the examined traits. The varieties Pitbull, Cubus, Kodex and Bagou were found to be highly susceptible to FHB. The presence of the dwarfing allele Rht-D1b resulted in a significantly higher mean symptom score and also in a higher affection of the other traits. Nonetheless, the analysis of frequency distributions in symptom scores showed the presence of resistant lines also among the GA insensitive lines, but with a lower frequency than in the group of GA sensitive genotypes. A relatively greater effect on manifestation of the disease had plant height, and therefore it is suggested that the adverse impact of Rht-D1b on FHB resistance could be to a high degree excluded by opting for taller Rht-D1b genotypes.

Various concentrations of indolyl- and naphthylacetic acids were applied to ten varieties of winter wheat prior to planting in a replicated field trial, one-half of each plot receiving seed dusted with Ceresan plus phytohormone, and the other half receiving an equal quantity of seed of the same variety dusted with Ceresan only.Some differences between the hormone-treated and untreated sub-plots in respect of early growth and subsequent density of stand were apparent to visual inspection. There were also statistically significant differences in respect of straw production, and of yield, weight per bushel, and nitrogen content of grain. The effects on grain yield were complicated by the differential response of varieties to the same treatment, and at the higher concentrations some depressions of yield resulted. On the average both chemicals tended slightly to reduce the nitrogen content of the grain produced.The results as a whole seem to demonstrate the physiological activity of both substances tested when applied in this way. Further investigation of dosages, varietal characteristics, and seasonal effects, however, will be required before general conclusions can be reached.
