  • Yield loss of wheat and barley due to meteorological constraints has been analyzed in order to get the basic information, which will lead to the counter-measures for dissemination of agricultural technology and administration. These meteorological damages were analyzed on the results of percentage yield loss and mechanism of damage and the aspects of constraints were explained. The annual yield loss of wheat and barley were 21.7% by meteorological stress: Cold damage, 5.9% ; excessive soil moisture, 5.6% ; lodging, 2.9% ; drought, 3.0% ; disease, 4.3% etc. Those damages by the stresses mentioned above and rain damage were analyzed in relation to the growth stages and the degrees of damage. The predispositions and the growth of wheat and barley to those meteorological stress are also discussed. Varietal resistances of wheat and barley to those stresses were indexed and the physiological and morphological characteristics of these resistant cultivars are described. Cultural practices to minimize the damages were also reviewed.

  • 국내산 밀품종인 그루밀과 탑동밀의 성분분석과 수입밀과 전분의 대체 비율 또는 가수량을 달리 하였을 때의 반죽 및 국수의 품질특성을 살펴보았다. 국내산 밀가루는 수입 연질밀에 비해 단백질과 회분함량이 높았다. 국내산 밀가루반죽은 수입밀보다 수분흡수율과 반죽도달시간이 높게 나타났으며, 안정도는 낮고 약화도가 높게 나타났다. 탑동밀의 반죽형성시간이 가장 높았으며, 그루밀이 가장 짧게 나타남으로써 연질밀일수록 반죽형성시간이 짧게 나타남을 알 수 있었다. 탑동과 그루밀에 수입밀 혼합량이 증가함에 따라 수분 흡수율은 감소되는 경향을 보였으며, 반죽형성시간은 탑동밀에 수입밀 30% 대체까지는 감소하였다. 수입 산 밀가루의 첨가는 국내산 탑동과 그루밀의 연화를 감소시켰으며, 가수량이 증가함에 따라 전 시료의 점착성이 증가하였는데, 특히 그루밀의 가수량 65%, 10~20% 수입밀 혼합시 가장 점착성이 높게 나타났다 견고성은 가수량이 증가할수록 감소하였고, 품종별로는 탑동밀이 수입산 밀가루에 비하여 높은 견고성 을 보였다. 국수의 기계적인 조직감은 탑동밀에 수입 밀의 첨가는 인장력은 증가하고 인장길이는 감소되었으며, 그루밀은 이와는 반대의 경향이 나타났다. 국수의 견고성은 대조구(수입산 밀가루)>탑동>그루밀 순서였으나, 수입산 전분 첨 가량이 증가함에 따라 품종에 관계없이 견고성, 부착성및 씹힘성 모두 증가하였고, 3%이상 첨가시 대조구와 거의 비슷한 경도를 나타내었다. 전분의 첨가에 따른 조리된 국수가닥의 인장력은 대조구인 수입산 밀가루에 비하여 탑동과 그루밀에서 비교적 낮은 값을 보였고, 인장길이는 대조구에비하여 전반적으로 늘어나지 않아 국내산 밀이 대조구보다 쉽게 끊어지고 늘어나지도 않음을 알 수 있었다 따라서 그루와 같은 한국산 연질밀은 아밀로즈 함량이 높거나 단백 질함량이 상대적으로 낮은 밀가루를 혼용한다면 수입밀에 뒤지지 않는 제면 성질을 가지며 유연성을 더욱 향상시킬 수 있음을 알 수 있었다.

  • 본 연구는 표준화된 밀 메주를 제조하기 위해 원료밀의 도정에 따른 수침 및 증숙조건과 품질특성을 조사하였다. 수침시간에 따른 2분도 밀, 5분도 밀, 통밀, 밀가루의 물리적 특성변화를 조사하기 위해 무게, 부피, 수분 함량, 수분 흡수량을 살펴 본 결과, 대부분의 밀에서 수침 4시간 이후에는 평형상태에 도달하였다. 원료밀 종류에 따른 증숙시간을 조사한 결과, 통밀을 제외한 밀원료의 증숙시간은 $100^{\circ}C$에서 10분이 적합하였다. 최적 수침 및 증숙조건으로, 가공한 2분도 밀과 5분도 밀을 각각 A. oryzae와 B. subtilis M1으로 발효하여 우리밀 메주를 제조한 후 일반 성분 및 효소역가를 비교한 결과, 황국균을 사용한 경우 발효 효율이 더 우수하게 나타났다. 또한 2분도 밀보다 5분도 밀에서 총당, 환원 당 및 ${\alpha}$-amylase 역가가 높게 나타나, 우수한 밀 메주의 제조를 위해 5분도 밀을 A. oryzae로 발효하는 것이 효율적이라 사료된다.

  • Wheat is one of the most important crops in production and consumption. Despite increasing of importance, the self-sufficiency of wheat is less than 2% in Korea. To improve yield potential and broaden the genetic pool of common wheat in Korea, introduction of alien germplasms into the Korean wheat breeding program is suggested. For effective utilization of the germplasm, we introduced total 1,195 germplasms from the world, which were provided by National Plant Germplasm System (NPGS, USDA) and evaluated the yield, field performances and agronomic traits for 8 years. Among 55 countries, germplasms from Canada, Ethiopia, Mexico and United States accounts for 78%, especially germplasms collected from United States accounts for 50%. Yield comparison of germplasms and collected region analysis indicate that the high yielding germplasms are collected from countries or states of particular range of latitude. The combination analysis of the yield and agronomic traits and the geographical information of collected region will be utilized for improving Korean wheat breeding programs.

  • End-use properties of six Korean waxy wheat lines and their parental plants were evaluated in this study. Korean waxy wheat lines showed unsuitable characteristics for end products, such as sticky crumb of bread, sticky cooked wet and dry noodles and small cookie diameter. Korean waxy wheat lines produced lower loaf volume and less desirable crumb grain structure of bread, and lower chewiness of cooked wet and dry noodles than their parental plants even though Korean waxy wheats were much higher in protein content and SDS-sedimentation volume than their parental plants. We observed adverse effects of high flour protein content in Korean waxy wheat lines, such as smaller cookie diameter and harder snapping force than those produced from their parental plants.

  • The rheological properties of dough made the substitution of wheat flour(composite flour) at the levels of 0%, 5%, 10% and 15% soymilk residue flour, with addition of vital wheat gluten at the levels of 3, 6 and 9% were investigated. And nutrition contents of soymilk residue flour were analyzed. The results were as follows; Principal components of soymilk residue flour were 22.0% crude protein, 13.2% crude lipid, 54.3% carbohydrate, 27.2% dietary fiber and $220{\mu}g/g$ isoflavones. Free amino acid component of soymilk residue were L-glutamic acid, L-leucine, L-lysine, L-valine, L-phenylalanine, L-isoleucine, L-threonine, L-methionine and L-cystine. Total dietary fiber content of bread with soymilk residue and wheat flour were 5% soymilk residue; 3.50%, 10% soymilk residues; 4.65%, 15% soymilk residues; 5.96%, and wheat flour bread: 2.1% respectively Mixing water absorption capacity was increased by increasing amounts of added soymilk residue and vital wheat gluten. Dough development time was increased by increasing amounts of added soymilk residues, while decreased by increasing amounts of vital wheat gluten. The dough volume of composite flour with 5%, 10% and 15% soymilk residue flour were the smaller than wheat flour dough. But the dough volume was increased by added vital wheat gluten, and the composite flour with 5% soymilk residue flour and 9% vital wheat gluten was better than the others. This study proved that the dough volume of composite flour with 5% soymilk residue flour and 9% vital wheat gluten was better than the others. On the other hand, the soymilk residue flour contains dietary fiber, isoflavone, protein, lipid and carbohydrate. Therefore the soymilk residue flour will be very useful as food material.

  • The production of spring wheat, the major crop in Mongolia, is accounting for 98% of the cultivated area. Collection, conservation and utilization of wheat germplasm resources play an important role in wheat breeding and production in Mongolia. Understanding genetic variability in the existing genebank accessions is important for collection and conservation of wheat germplasms. To determine the genetic diversity and population structure among a representative collection of Mongolian local wheat cultivars and lines, 200 wheat accessions were analyzed with 15 SSR markers distributed throughout the wheat genome. A total of 85 alleles were detected, with 3 to 5 alleles per locus and a mean genetic diversity value of 5.66. The average genetic diversity index was 0.68, with values ranging from 0.37 to 0.80. The 200 Mongolian wheat accessions were divided into two subgroups based on STRUCTURE, un-rooted NJ cluster and principal coordinate analyses. The results from this study will provide important information for future wheat germplasm conservation and improvement programs with Mongolian genebank.

  • 재배 환경 조건이 주요 밀 품종의 품질에 미치는 영향을 보기 위하여 조광을 포함한 9개 품종을 8개 지역에 재배하여 지역별 기상인자와 소맥분 단백질함량 및 침전가와의 관계를 검토한 결과는 다음과 같다. 1. 소맥 재배기간중의 기온이 낮은 북부 일수록 단백질 함량과 침전가는 품종에 관계없이 높은 경향을 보였다. 2. 소맥분의 단백질 함량 및 침전가에 미치는 가장 큰 기상요소는 등숙기간중의 평균 기온이었다. 3. 기온이 낮은 북부지역일수록 출수일이 늦어져서 등숙기간의 기온이 높아진다. 등숙기간의 평균기온이 높은 지방일수록 소맥분의 단백질 함량 및 침전가는 높아졌다. 4. 소맥의 단백질 함량에 미치는 온도반응은 품종에 따라 차이가 있었으며 온도반응이 예민한 품종은 Altas 66, Kitakamikomugi 및 영광이었고 둔감한 품종은 원광, Centurk 및 Bezostaya 이었다. 5. 소맥분의 침전가에 미치는 온도반응은 침전가가 높은 Atlas 66, Centurk, NE 701132, 품종들에서 높았고 침전가가 낮은 Roussalka 및 국내 품종들에서는 둔감하였다.

  • This study was carried out to establish methods for irradiation detection of irradiation in Korean wheat flour by pulsed photostimulated luminescence (PPSL) and viscometric methods. The photon counts of the irradiated Korean wheat flour measured by PPSL immediately after irradiation increased with increasing irradiation dose. The photon counts in the irradiated Korean wheat flour almost disappeared with lapse of time after storage in normal room conditions, but irradiation detection was still possible after 6 months in darkroom conditions. All irradiated samples indicated a decrease in viscosity with increasing stirring speeds (rpm) and irradiation doses. Irradiation at 1 kGy significantly decreased the viscosity. Consequently, these results suggest that the detection of irradiated Korean wheat powder is possible by both viscometric and PPSL methods.
