Early in the growing season of 1976, rain and cool weather favored the blighting of leaves of young plants of barley by Fusarium nivale. The fungus was recovered in culture from infected foliage, and the perithecia of Calonectria nivalis were demonstrated to be present as well as the Fusarium state. On 22 April 1976, in Suweon, plants pulled at random revealed stem lesions from which F. nivale was cultured. On S May 1976 near Kwangju. Perithecia were found embedded within leaf sheaths and blades of mature wheat and barley plants. It was evident in the 1976, 1977 season that Fusarium(Calonectria) nivale was common but unrecognized as an early season pathogen of barley in Korea. The probable source of primary inoculum was the infected refuse from the previous season's barlry and wheat crops. Stem lesions caused by this fungus were considered to he detrimental to the maximum yield of barley or wheat,

This study was undertaken to find out national level changes in area, production and yield of two major staple crops wheat and potato in Bangladesh. The time series of secondary data was collected from yearbook of agricultural statistics under Bangladesh Bureau of Statistics (BBS) and used for the statistical analysis during the thirty-year period of 1989/90-2018/19. Moreover, selected data were divided into two groups and regarded as segment (1989/90-2003/04, 2005/06-2018/19) to examine the significant level in each crop. The results of different statistical techniques showed that wheat cultivated area and production were satisfactory level but yield was not too much standard in context of country demand. In the case of potato, yield as well as cultivated area and production were crossed the significant level and fulfilled the demand of population. In recent few years, the ratio of potato production rapidly increased, compared with the cultivation area. Based on segment (period) analysis, at the first half wheat production was always below, compared with the area but second half nine years saw slightly improved. On the other hand, in both segment potato growth rate in area, production and yield were increased throughout the study period. The highest instability was also shown in area, production and yield of potato during whole as well as segmented period. There was always a positive relationship between country’s demand and supply. Both wheat and potato are considered as staple crops and based on the productive capability over cultivated area, potato showed the higher productivity for the country of Bangladesh. In consequences, potato consuming demand also rapidly increased all over the country, compared with past respectively.

Wheat is an economically important cereal worldwide and is a staple food in many countries. Extensive researches have been performed on the nutritional value and antioxidant potentials of sprouts of legumes like soybean, however very limited studies have been carried out on the sprouts of Korean wheat cultivar. The objective of this study was to investigate the phytochemical and antioxidant potentials of Korean wheat sprouts. The sprouts were grown for 10 (WS-10), 20 (WS-20), and 30 (WS-30) days at room temperature. The pH, color, chlorophyll, free amino acid, 1,1-diphenly- 2-picrylhydrazyl (DPPH), and total polyphenol content of the sprout samples were determined. The pH of sprouts was increased in the older sprouts. Color values were significantly influenced by the age of sprouts. The chlorophyll content was lowest but the total free amino acid content was highest in WS-30. On the other hand, the DPPH free radical scavenging potential and total polyphenol content were lower in WS-30. The results suggested that Korean wheat sprouts could be a potential source of nutrients and natural antioxidants.

This study investigated the relationship analysis between wheat cultivated area and the climate data in Sindh province of Pakistan. The extraction of wheat cultivation area is detected using the remote sensing technique. The analysis of the study area reveals the annual mean maximum and the mean minimum temperature tends to risen with a large range of changes. The trend of average annual precipitation showed a large change, thus it was confirmed that the increase and decrease yield of wheat were depend on the various growth periods of wheat crop. The most influential factors are the annual mean precipitation and the annual mean minimum temperature at the seedling stage of wheat crop. The annual precipitation, annual mean maximum, and the annual mean minimum temperature are significant at the growth period. The annual mean maximum and the annual mean minimum temperatures are significant during the ripening stage of wheat crop in the study area. The results of the study showed that wheat production varies with climate change in the Sindh province. In addition, this study will be used as an important basis for solving crop cultivation areas and production problems caused by climate change in the region.

This study examined the efficiency of satellite images in terms of detecting wheat cultivation areas, and then analyzed the possibility of climate change through an correlation analysis of time series climate data from the western regions of Gyeongnam province, Korea. Furthermore, we analyzed the effect of climate change on wheat production through a multiple regression analysis with the time series wheat production and climate data. A relatively accurate distribution was achieved on the wheat cultivation area extracted through satellite image classification with an error rate of less than 10% in comparison to the statistical data. Upon correlation analysis with time series climate data, significant results were displayed in the following changes: the monthly mean temperature of the seedling stage, the monthly mean duration of sunshine, the monthly mean temperature of the growing period, the monthly mean humidity, the monthly mean temperature of the ripening stage, and the monthly mean ground temperature. Accordingly, in the study area, the monthly mean temperature, precipitation, and ground temperature generally increased whereas the monthly mean duration of sunshine and humidity decreased. The monthly mean wind speed did not display a particular change. In the multiple regression analysis results, the greatest effect on the production and productivity of wheat as climate factors included the annual mean humidity of the seedling stage, the annual mean temperature of the wintering period, and the annual mean ground temperature of the ripening stage. These results demonstrate that there is a change in wheat production depending on the climate change in the study area. in addition, it is determined that this study will be used as important basic data in the resolution of food security problems based on climate change.

Burdock powder (BP) has shown diverse functional activities; thus, it seems a good way to increase its consumption by incorporating BP into suitable food products such as cookies. Studies were carried out on cookies prepared by incorporating BP (2%, 4%, 6%, and 8%) into wheat flour. The cookie dough and cookies were evaluated for their physical, chemical, and sensory characteristics. The pH and density of cookie doughs ranged from 6.70-6.85 and 1.19-1.21, respectively, with no remarkable differences. Moisture content and spread factor of cookies appeared to increase with higher content of BP in the formulation but did not show significant differences (p>0.05). For color values of cookie surface, L*, a*, and b*-values significantly decreased as a result of BP substitution (p<0.05). The cookies became crispier as indicated by the reduction in the breaking strength value from 26.71 to 17.83 N. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging activities were significantly increased (p<0.05) with higher substitution of BP, and they were well correlated. Hedonic sensory results indicated that cookies supplemented with 2% BP received the most favorable acceptance scores for all sensory attributes evaluated. Overall, cookies with BP could be developed with improved physicochemical qualities as well as consumer acceptability.

Hexaploid wheat (Triticum aestivum L.) exceeds about 30% of the world’s cereal production and cultivated over 220 million ha worldwide. Heat stress during the grain filling period gives detrimental effect on crop yields and has emerged as a serious problem throughout the world. Korean wheat cultivars that were released since 1960s were developed for various aims such as winter hardness, earliness, and pest resistance, etc. However, heat stress resistance is an emerging target for wheat breeding nowadays. Selected 11 Korean wheat cultivars (“Baegjoong”, “Dajung”, “Goso”, “Hanbaek”, “Jokyung”, “Joeun”, “Jopum”, “Keumgang”, “Olgeuru”, “Sinmichal”, “Uri”) were exposed to high temperature from DAF (days after flowering) 9~13. In this study, plant responses to heat stress as measured by reduction ratios of total chlorophyll contents, 100 seed weight, shoot dry weight can be translated into degree of tolerance. Therefore, these parameters can be used in wheat breeding for heat tolerance during grain filling period. The obtained results allow us to classify cultivars for heat stress tolerance. Pedigree information of Korean cultivars was shown that wheat line of either tolerant, moderate tolerant, or susceptible trait is succeeded to their descendent, which enable breeders to develop heat stress tolerant wheat by appropriate parental choice.

Yellow alkaline noodles were prepared with various Korean wheat cultivars including different protein and amylose contents and made from two types of noodle machines. Korean food companies and restaurants generally used noodle machine made in Korea, whereas research institutes mainly practiced with noodle machine made in Japan. Noodle dough sheet from Korean machine showed 5% higher water absorption and 30 min shorter resting period than the noodle dough from Japanese machine because of the difference of size and weight of roller in two types of the machines. In 15 Korean wheat cultivars, thickness of noodle dough sheet was positively correlated with protein content and mixograph water absorption regardless of both types of the machines. Cooked noodles from Korean machine showed higher hardness and lower springiness than noodles from Japanese noodle machine, but difference in cohesiveness of cooked noodles was not found between two different noodle machines. In the three Korean wheat cultivars with different protein content, thickness of noodle dough sheet was also positively correlated with protein content, SDS sedimentation volume and mixing time of mixograph in both types of the machines. The more protein content increased, the more hardness of cooked noodles increased regardless of both types of the machines. However, springiness and cohesiveness of cooked noodles were not significantly correlated with protein content. In waxy and partial waxy wheat cultivars, lightness of noodle dough sheet from Korean noodle machine positively correlated with amylose content. Amylose content and setback in pasting properties were positively correlated with hardness, springiness, and cohesiveness of cooked noodles while both damaged starch and breakdown were negatively correlated with those.

Eleven RAPD primers were assessed to analyze genetic diversity of Korean wheat varieties and to develop DNA marker for cultivar identification. The average of the number of polymorphic bands was 5.2 and PIC values showed 0.48, respectively. Ten major clades were presented by phylogenetic analysis. Three cultivars containing Uri, Hanbeak and Jonong were distinct from the others in the phylogenetic dendrogram. Seven cultivar-specific fragments were detected from 11 RAPD fingerprinting among 35 wheat cultivars and they were sequenced. Four Korean wheat cultivars, Eunpa, Jopoom, Yeonbaek and Jeokjoong, were identified newly by four markers, 84, 173, 174 and KWSM011. We convince that these new DNA markers are useful for cultivar fingerprinting and are applied to marker-assisted selection in wheat breeding program.

Wheat is one of major crop and wheat flour is used to various end-use products such as bread, cookies and noodles due to its unique characteristic of it as elasticity and viscosity. Wheat consumption has been generally increasing in not only US and Europe but also Korea. Nevertheless, gluten proteins in wheat endosperm are cause of allergy by food ingestion. Hence, studies on the allergy have been conducting and have been attracting public attention. Herein, we report studies on research trend of the issue with research papers over the last decade for suggestion of future research direction. Since 2012, studies on allergy of gluten proteins have been dramatically increased based on the number of published papers related to the issue. As results of research activities by country, the Europe accounted for 60% corresponding to the number of papers. Next US (13%), Japan (9%), China (5%), and Korea (2%) came. In Korea, studies on allergy of gluten protein are less studied. In the field of studying of gluten allergy, there are two major technologies as preclinical technology and genome research accounted for 58% and 26%, respectively. In Korea, the study on glutenin proteins which is closely related to wheat allergy is actively performed. Therefore, it can be expected that research will be become more active.

Mixolab is suitable to evaluate mixograph and farinograph for testing dough rheology and amylopgraph for properties of starch pasting with a view to analyze protein and starch quality at the same time. Mixolab analysis revealed that water absorption and dough development time of Korean wheat cultivars were similar to it of soft wheats and flour while dough stability and protein weakening of Korean wheat cultivars were similar to it of hard wheat and strong flour. Also, starch properties of Korean wheat cultivars showed similar properties of hard wheats. There was a significantly positive correlation between mixolab and mixograph in the water absorption of dough, whereas no correlation was observed between them in dough development time and stability. Furthermore, maximum viscosity of starch and breakdown in amylopgraph were correlated to stabilities of pasting and cooking and setback in mixolab. Resultantly, in mixolab, properties of dough and protein highly and positively correlated to loaf volume, hardness of noodles, and size of cookies i.e. diameter. Moreover, positive correlation was identified between viscoelasticity of noodles and properties of protein, pasting, and setback in mixolab.

This study was executed to establish a basis of evaluation of starch properties of Korean wheat cultivars e.g. damaged starch, swelling, and pasting properties for Korean wheat breeding program. Damaged starch is critical evaluation factor for flour milling related industry because it influences water absorption and color of dough for processing quality and preference of end-use products. The present results revealed that there was significantly high positive correlation between the results of damaged starch analysis by amperometric (SD-matic) and enzymatic (Megazyme assay) methods. Evaluation of damaged starch must be considered as one factor to evaluate properties of starch due to its accuracy and a stable efficiency for the wheat breeding program. Properties of swelling and pasting of dough were important for cooking time and texture. Nevertheless, it was impossible to evaluate starch extracted from flour in the wheat breeding program i.e. small amount of flour or small number of spikes Comparison of results of evaluation of properties of swelling and pasting with starch or flour, the evaluation using flour positively correlated with the other evaluation using starch. In addition, swelling evaluation must be considered to apply for the wheat breeding program because the result of evaluation of swelling property, which possible to evaluate with low efficiency, and the quantity of a sample is highly under positive correlation with paste peak viscosity. In the future, studies using NIR (Near Infrared) analysis must be necessary to evaluate starch properties with grains in early generation lines for improvement of wheat breeding program.
