The wheat proteins soluble in chloroform-methanol mixtures are associated with several kinds of food allergies. A separation method based on capillary zone electrophoresis (CZE) with UV detection was developed for the analysis of these mixtures. An acidic phosphoric acid/β-alanine (pH 2.5) buffer containing HPMC, urea and acetonitrile was used for the separation. The capillary electrophoresis (...

Samples of grain from 40 New Zealand wheat and barley crops harvested in 2000 were assayed for Fusarium infection. Grain from all crops was infected, and Fusarium incidence ranged from 3 to 52% of grains infected, with a mean of 14%. Incidence of Fusarium was higher in spring wheat than in autumn wheat or spring barley. The highest level of infection (52% grains infected) was found in Otane whe...

The effect of greenbug, Schizaphis graminum (Rondani), feeding on the yield of four winter wheat cultivars commonly grown in Oklahoma was studied. Cultivars tested were 'Karl', a recent derivative 'Karl-92', and '2163', all greenbug-susceptible cultivars; and 'TAM-110', a cultivar with resistance to biotype E greenbugs. The objectives were to determine the effect of different greenbug densities...

Quantitative and Qualitative Evaluation of Spring Bread Wheat (Triticum aestivum L.) Cultivars under Different Planting Dates

Ordoñez, M. E., and Kolmer, J. A. 2009. Differentiation of molecular genotypes and virulence phenotypes of Puccinia triticina from common wheat in North America. Phytopathology 99:750-758. Wheat leaf rust caused by Puccinia triticina is widely distributed in the wheat growing regions of the United States and Canada, and is subject to selection for virulence phenotype by leaf rust resistance gen...

a total of 165 wheat landraces with their originated from northwest regions of iran were studied at research station of agricultural faculty, univ. of tabriz, using two experimental designs in two spring and fall growing seasons. during these experiments, growth habits of 104 wheat landraces were assessed and their representative seeds harvested in similar conditions. these landraces were analy...

Starch and cellulose are among the best known renewable reinforcing components. Scientists are continuously looking for various renewable sources such as flax, hemp, jute, and corn hulls with polymer matrixes to form composite materials and make structural biocomposites a reality. Wheat is a major cereal grain in the US and the world. During wheat milling, a large amount of wheat bran, a by-pro...

Aluminum (Al) toxicity is the key factor limiting wheat production in acid soils. Soil liming has been used widely to increase the soil pH, but due to its high cost, breeding tolerant cultivars is more cost-effective mean to mitigate the problem. Tolerant cultivars could be developed by traditional breeding, genetic transformation or introgression of genes from wild relatives. We used 30 wheat ...
