The simplified AFLP method was developed and evaluated for identification and genetic diversity studies of wheat cultivars. Selective primers exploited in AFLP assay based on a single cutting enzyme PstI ((PstI)AFLP) generated total of 111 robust fragments, including 67 (60%) monomorphic and 12 (11%) cultivar-specific markers. Average similarity between 15 cultivars was 0.650, and varied from 0...

the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...

terminal heat stress in mediterranean climates like ahwaz is reduced wheat yield. in order to study effect of terminal heat stress on yield and yield components of 20 spring bread wheat cultivars, an experiment was conducted in ramin university of agricultural and natural resources, ahwaz in 2007-2008. the experimental design was stripe block design in randomized complete block design with thre...

The utility of mining DNA sequence data to understand the structure and expression of cereal prolamin genes is demonstrated by the identification of a new class of wheat prolamins. This previously unrecognized wheat prolamin class, given the name δ-gliadins, is the most direct ortholog of barley γ3-hordeins. Phylogenetic analysis shows that the orthologous δ-gliadins and γ3-hordeins form a dist...

One of the goals of organic crop production is to grow species which combinetraditional pro-healthy properties, innovative cultivation practices and harmonywith the environment. Among the ancient species the spring spelt is especiallypredisposed for organic farming. In comparison with common wheat spring spelthas a relatively short research history on physiological analysis of growth anddevelop...

twentieth century had faced considerable increase in crops yields. nonetheless, it is postulated that world population will reach 10.4 billion until 2050 which means the demand for agricultural crops production should be increased between 60 and 110 percent. in the present study, improvements in grain yields of wheat, maize and rice during the recent decades in iran were studies through analyzi...

this study was conducted to determine regression equations for the prediction metabolizable energy value corrected for zero nitrogen retention (amen) in 12 wheat cultivars (mahdavi, chamran, sabalan, sepahan, sivand, alamoot, sholeh, neishaboor, pishtaz, bahar, shiraz and shahpasand) cultured in alborz province of iran. chromic oxide marker bioassay was used to determine wheat cultivars nitroge...
