One of the most important limiting factors of high-quality wheat production is Fusarium head blight infection. The various Fusarium species not only may cause severe yield loss but—due to toxin production—the grains also might become unsuitable for animal and human nutrition. In the present research, our aim was to examine the Fusarium resistance of a special mapping population (’BKT9086-95/Mv Magvas’) and identify the genetic factors and chromosome regions determining the tolerance to Fusarium culmorum and Fusarium graminearum. The connection between the genetic background and the Fusarium head blight sensitivity was confirmed by the analysis of variance in the case of three markers, among which the co-dominant pattern of the gtac2 and gtac3 amplified fragment length polymorphism (AFLP) markers might indicate a marker development possibility. Consistently expressed quantitative trait loci (QTLs) were identified on the chromosomes 2A, 2B, 2D, 5A, and 7A. Loci linked to resistance were identified on 11 chromosomes. During the investigation of phenological and morphological traits (heading date, plant height, ear compactness) influencing the head blight resistance and the location of the resistance QTLs, the total overlap was found in the case of the region identified on chromosome 2D and partial overlap on chromosomes 2A and 2B. Whereas 5A may be a rare allelic variant of a novel QTL.

Head scab is historically a devastating disease affecting not just all classes of wheat but also barley and other small grains around the world. Fusarium head blight (FHB), or head scab, is caused most often by Fusarium graminearum (Schwabe), (sexual stage – Gibberella zeae) although several Fusarium spp. can cause the disease. This study was conducted to determine the effect of mass selection for FHB resistance using an image-based optical sorter. lines were derived from the C0 and C2 of two populations to compare genetic variation within populations with and without sorter selection. Our overall hypothesis is that sorting grain results in improved Fusarium head blight resistance. Both of the used wheat derived line populations have genetic variation, and population 1 has more than population 17. They are significantly different from each other for fusarium damged kernel (FDK), deoxynivalenol (DON), and other FHB traits. Although both populations are suitable to be grown for bulks, population 1 seems better since it has more genetic variation as well as lower FDK and DON, and earlier heading date. Lines within each population were significantly different and some lines in each population had significantly lower FDK and DON after selection using an optical sorter. Some lines had significant reduction in both FDK and DON, and some others had either FDK or DON reduction. Lines of population 1 that had significant reduction, were more numerous than in population 17, and FDK and DON reduction were greater.

Since late 2010 and early 2011, the Arab region has witnessed mass protests in Tunisia, Egypt, Libya, Syria, Yemen, Iraq, Bahrain and other countries that have been referred to in the political, media and other literature as the Arab Spring. These movements have had a profound effect on the stability of the regimes Which took place against it, as leaders took off and contributed to radical reforms in party structures and public freedoms and the transfer of power, but it also contributed to the occurrence of many countries in an internal spiral, which led to the erosion of the state from the inside until it became a prominent feature of the Arab) as is the case in Syria, Libya, Yemen and Iraq.

Abstract:In model experiments in soil culture, the effect of different methods of treatment with sodium selenite on the photosynthetic activity of spring wheat variety Zlata was studied under extreme growing conditions. Under drought conditions, the inhibition of the growth of the photosynthetic surface of spring wheat plants was revealed. Under conditions of excessive water supply, a sharp decrease in the area of the assimilating surface of wheat plants was observed. The positive effect of sodium selenite solution on the photosynthetic activity of spring wheat plants was established with insufficient and excessive water supply to wheat plants.
