A high-speed sorter was used to remove kernels infected with Karnal bunt from 1800g wheat samples. When the sorter removed about 8% or more of the sample, the reject portion contained 100% of the bunted kernels. Concentrating the bunted kernels in a smaller sample size will reduce sample inspection time and should reduce inspection errors. One high-speed sorter can process up to 8800 kg/hr, thu...

Cell walls are complex structures surrounding plant cells with a composition that varies among species and even within a species between organs, cell types and development stages. For years, cell walls in wheat grains were described as simple walls consisting mostly of arabinoxylans and mixed-linked beta glucans. Proteomic and transcriptomic studies identified enzyme families involved in the sy...

Ryegrass is the probably the most damaging weed to winter wheat over a large part of the high rainfall area in the central, north and east Texas. Economic losses in wheat occur through reduced grain yield, quality, foreign matter, and harvest efficiency. Yield loss can exceed 90% in heavy infestations. In addition to yield reduction, reduced harvest efficiency results in lower test weight, high...

Phaeosphaeria nodorum (E. Muller) Hedjaroude (anamorph = Stagonospora nodorum (Berk.) Castellani & E.G. Germano) causes Stagonospora nodorum blotch (SNB), a disease of wheat (Triticum aestivum) leaves, stems, and glumes. SNB occurs persistently, but with varying degrees of severity, in the eastern U.S. soft red winter wheat region. Acceptable levels of partial resistance are available in adapte...

Wheat (Triticum aestivum L.) is one of the most important crops cultivated worldwide. Identifying the complete transcriptome of wheat grain could serve as foundation for further study of wheat seed development. However, the relatively large size and the polyploid complexity of the genome have been substantial barriers to molecular genetics and transcriptome analysis of wheat. Alternatively, RNA...

This research was carried out to assessment agro physiological traits of bread wheat affected salinity stress, Nano zinc oxide and arbuscular mycorrhiza (AM) fungi under greenhouse condition via factorial experiment based on randomized complete blocks design with three replications. Experimental factors included salinity stress in three levels [no-salt (S0) or control, salinity 40 (S1), and 80 ...

In higher plants, seed storage proteins (SSPs) are frequently expressed from complex gene families, and allelic variation of SSP genes often affects the quality traits of crops. In common wheat, the Glu-D1 locus, encoding 1Dx and 1Dy SSPs, has multiple alleles. The Glu-D1d allele frequently confers superior end-use qualities to commercial wheat varieties. Here, we studied the haplotype structur...

In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...

to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...
