Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat var...

Hexaploid Wheat (Triticum aestivum L.) is one of the most important food cereals grown in many areas worldwide. World population is to increase by 2.6 billion in 2050. Ethiopia is one of the world’s nine countries needed to increase food production. Since few studies on genetic diversity & in adequate evaluation of bread wheat varieties; my objective the project is to study genetic diversity of...

A field experiment was carried out in the Light village of Netrokona Sadar during the period from December 2010 to March 2011 to study the performance of some wheat varieties in terms of nutrient contents and their uptake. The experiment comprised of five varieties of wheat viz. BARI Gam 25, Shatabdi, BARI Gam 26, Prodip and Bijoy. The experiment was laid out in a randomized complete block desi...

Glutenins from II varIetIes of wheat representing the five different classes commonly grown in the United States were compared in terms of protein composition and sensitivity to salt precipitation. Gluten obtained from the different wheats varied from 8 to 10.5 % for soft wheats to about 9 to 11 % for hard wheats and 17 % for durums. Gliadinglutenin ratios were similar in all varieties investig...

A total of 206 wheat and 200 barley farmers were interviewed in northeastern Syria to understand farmer perceptions and practice relating to modern varieties, seed sources and seed quality. Wheat farmers had better awareness and grew modern varieties (87%), applied fertilizers (99.5%), herbicides (93%), seed treatment (90%) or insecticides (41%). In contrast barley growers had low awareness (36...

in order to investigate the competitive effects of wild mustard on yield and yield components of wheat cultivars, field experiments was conducted in gorgan reaserch station during 2010-2012 growing seasons. the experiments were laid out in four replicated, factorial arranged rcb design. factors of the experiments included five different densities of wild mustard (0, 4, 8, 16 and 32 plants.m-2) ...

The English grain aphid, Sitobion avenae (F.) (Hemiptera: Aphididae), is an important pest insect of wheat, Triticum aestivum (L.), in China. Grain aphid biotypes are necessary to breed aphid-resistant wheat varieties; however, none have currently been identified. Here, we describe a method to identify grain aphid biotypes and survey the aphid biotype variation in the wheat growth area of China...

In the present study phytase, phytate and protein content were determined in twenty wheat varieties. Among twenty wheat varieties, LOK-1 variety was found to have higher content of phytase, phytate and protein. During the study, phytase activity was 197.30±0.65 to 2132.77±0.29 nM/min/g, phytate 2.90±0.35 to 7.07±0.09 and protein 77.07±0.64 to 148.40±0.31 mg/g found, respectively through differe...
