Winter Wheat Varieties

Experimental researches had been carried out during 2012–2016 in the crop rotation of Sumy National Agrarian University (SNAU) of the Ministry of Education and Science of Ukraine. Soils on the experimental field of SNAU – black soil typical deep, non-humusful medium-loam with high and medium provision with elements of mineral nutrition. The humus content about 3.9 %. The reaction of the soil solution is close to neutral (5.8). The analysis of the weather conditions of 2012–2016 researches was conducted on the basis of annual data provided by the meteorological station of the Institute of Agriculture of the North-East of the NAAS, located five kilometers from the experimental field of SNAU. The SNAU soils are classified in the second agro-climatic region of the Sumy region, which according to a long-term data is characterized by temperate continental climate with warm summers and not very cold winters with thaws. Average daily (average annual) air temperature during 2012–2016 fluctuated from +7.9 to +9.5 ºС, and the legth of the frost-free period was close to 230 days. Long-term indicator, precipitation falls within 597–600 mm, with most of it – in the warm period (April-October). In general, the weather conditions during the winter wheat vegetation periods differed from the average annual parameters of the temperature regime, the amount of precipitation and their monthly distribution. It should be noted the excess of temperature to the average long-term index, as well as a slight precipitation increasing. In general, it facilitated to a comprehensive evaluation of the studied Chinese varieties as for an adaptive ability under condition of Ukraine. The samples of Chinese winter wheat varieties which originated from the expeditionary gatherings conducted by V. A. Vlasenko in Gansu and Hebei provinces in (2000–2012) were the material for conducting researches. The cultivar Podolianka (the standard) was used in the study for comparison. The research was carried out using field, laboratory and mathematical-statistical methods. Phenological observations and records, evaluation and harvesting were conducted in accordance with generally accepted methods. The results of research as for adaptive potential of Chinese bread winter wheat varieties are presented. 50 new cultivars of Chinese origin were analyzed under the conditions of left-bank side of North-East Forest-Steppe of Ukraine: super-early varieties – 10 %; early ripening varieties – 54 %; middle-early varieties – 12 %; mid-ripening varieties – 24 %. As for the level of tolerance for winter conditions, all groups of alien crops were inferior to the standard (cultivar Podolyanka) though they had a great level of index (6.4–7.9 points). In general, Chinese cultivars under the conditions of the research were characterized by relatively satisfactory tolerance for winter conditions; 52 % of analyzed patterns wintered at the level of standard with 8 points. Among them: super-early varieties – 2 %; early ripening varieties – 20 %; middle-early varieties – 8 %; mid-ripening varieties – 22 %. As for the height of the plants we identified – from medium-sized (81‒110 cm) forms to dwarf (30-50 cm). The analyzed genotypes divided into medium-sized forms – 22 %, dwarf forms – 14 % and semidwarf forms – 64 %. There was a direct relation between: a plant height → group of ripeness (r = 0.96) → group of ripeness (r = 0.92) → resistance to overwintering (r = 0.78). Among the analyzed patterns high resistance against a group of diseases had the varieties: middle-early genotypes – Longzhong 10, Zhong mai 19, Shijra zhuang 8; mid-ripening genotypes – Longzhong 1, Longzhong 3, Longzhong 2, Longzhong 4, Longzhong 12, Longzhong 7; early ripening genotypes – DF529, Lankao 906, DF581, СА0175, Zhongmai 9, Shi 4185, Jimai 22, Shixin 733, Shimai 12. As for the crop better than the standard: early ripening varieties –Jimai 19, DF529; middle-early varieties – Shijiazhuang 8, Longzhong 10, Jingdong 8; middle-early varieties – NSA 97-2082, Longzhong 2, Longzhong 4, Longzhong 7, Longzhong 5, Longzhong 8, Longzhong 12, Longzhong 11, Longzhong 3. 16 % of analyzed cultivars distinguished by the totality of researched characteristics – DF529, Shijiazhuang 8, Longzhong 3, Longzhong 10, Longzhong 4, Longzhong 7, Longzhong 12, Longzhong 2.

Breeding wheat with blue grain was conducted at the Crop Research Institute in Prague. Initial donor material came from the legacy of Erich von Tschermak-Seysenegg. Long-term crosses with a series of winter wheat varieties were made with the aim of transferring blue grain colour into cultivated varieties. The prospective material was later handed over to Agrotest Fyto, Ltd., Kroměříž, where line no. 6 was selected from the population RU 440. At the end of 2011, the new winter wheat variety Skorpion with blue grain was registered in Austria. It is intended for special use in the food industry. The anthocyanins which it contains are considered to offer health benefits due to their antioxidant effects.

Gaudet, D. A., Puchalski, B. J., Despins, T., McCartney, C., Menzies, J. G. and Graf, R. J. 2013. Seeding date and location affect winter wheat infection by common bunt (Tilletia tritici and T. laevis) in western Canada. Can. J. Plant Sci. 93: 483–489. The majority of western Canadian winter wheat varieties are susceptible to common bunt (Tilletia tritici and T. laevis) and the risk to production, particularly in Saskatchewan and Manitoba, where the majority of production occurs, is unknown. Inoculated trials were employed to determine the effects of fall seeding date on bunt infection levels on one resistant and two susceptible winter wheat varieties at three locations in western Canada during three growing seasons from 2007/2008 to 2009/2010. Among the three locations, average infection levels were highest in Lethbridge, AB, followed by Glenlea, MB, and Saskatoon, SK. Later seeding resulted in high infection levels at all three locations in the susceptible varieties, particularly in Lethbridge, but high infection levels were observed in the earliest seeded treatments at both the Saskatchewan and Manitoba locations. The resistant variety Blizzard consistently exhibited infection levels of less than 3% infection across all environments. In a second test at conducted at Lethbridge, 10 of the 11 currently grown winter wheat varieties were susceptible to common bunt. These results indicate that there is a general risk of common bunt infection to winter wheat production across western Canada and that control measures must be taken until resistant varieties are developed.

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 tested the fertilizer reaction of four different winter wheat varieties in three different crop years, on chernozem soil, in long-term experiment. We examined the optimum fertilizer requirements and the maximum yield of the varieties. According to our results there were significant differences among the years: the yield of the winter wheat varieties changed between 1.4–6.1 t ha-1 in 2013, 3.8–8.6 t ha-1 in 2014 and 3.2–8.6 t ha-1 in 2015. The yield increasing effect of fertilization was significantly different in the tested years. The optimum level of fertilization was determined by, besides the genetic differences among the varieties, the crop year and the extent of fertilization. In milder winter months, due to the higher average temperatures, yields of winter wheat increased compared to an average crop year.

The purpose of the current work was to study the winter wheat varieties artificially infected with the North Caucasian population of brown rust to identify a damage degree. The study was carried out in two stages on two sets (8 and 10) of varieties with different level of resistance to the pathogen. The trials have established a high damage degree of rust on susceptible varieties, which resulted in productivity decrease from 16.3 to 32.2%. Among the varieties with the maximum damage degree, there was identified the most resistant variety ‘Tarasovskaya 29’ which, when completely (100%) damaged by the disease, showed a minimum productivity decrease, no more than 10.6%. The varieties being poorly susceptible to brown leaf rust reduced the productivity from 11.2% to 20.7%. The smaller indices of productivity decrease among this group were shown by the variety ‘Spartak’. Among the five varieties that showed moderate leaf rust damage, there were different degrees of productivity decrease. The variety ‘Donskaya Yubileynaya’ artificially infected with brown rust, showed a minimal productivity decrease and its structural elements, and it could be identified as the leaf rust resistant variety like the variety ‘Tarasovskaya 29’. When predicting the brown leaf rust epiphytoty, the susceptible and half-resistant wheat varieties require obligatory protection with fungicides.
