     In order to evaluate the genetic variability of Iranian wheat landraces and cultivars and to determine the relationship between grain yield and other traits, 313 Iranian wheat genotypes including 203 Iranian wheat landraces and 110 Iranian cultivars were planted in a three separated augmented design along with three check cultivars repeated in seven blocks in 2014 on the research field of ...

The prairie grass (Bromus catharticus Vahl) is the annual/biennial native forage of temperate climates most importance and diffusion in Argentina. Several authors have studied phenotypic variability morphophysiological characters cultivars populations grass. first commercial were heterogeneous that considered best adapted region Genetic, agronomic molecular characterization selection base germp...

Introgression of traits from wild germplasm into pip fruit cultivars by means of classical breeding is painstakingly slow. Introgression of e.g., the apple scab resistance gene Vf from Malus floribunda 821 into marketable high quality apple cultivars took approximately 50 years. In the mean time the Vf resistance is being broken down in Europe. For durable resistance, different resistance genes...

toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...

the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

ping system, the crop species, and the cultivar. Organic farmers require cultivars that can be multiplied and The natural approach taken by organic agriculture obviates the grown in the organic farming system with no undue use of synthetic agrochemicals and emphasizes farming in accordance with agroecological principles. Also implicit in this approach is an negative effects on the health and fu...

Historical adaptation of sorghum production to arid and semiarid conditions has provided promise regarding its sustained productivity under future warming scenarios. Using Kansas field-trial sorghum data collected from 1985 to 2014 and spanning 408 hybrid cultivars, we show that sorghum productivity under increasing warming scenarios breaks down. Through extensive regression modeling, we identi...

Estimates of genetic diversity can be based on different types of data. The aim of this research were to study genetic diversity among Croatian wheat cultivars by random amplified polymorphic DNA (RAPD) markers, morphological traits and pedigree records; to analyse differences between wheat cultivars from two breeding centres; and to evaluate usability of RAPD markers for estimation of genetic ...

Natural variation occurs in the uptake and distribution of essential and nonessential trace elements among crop species and among cultivars within species. Such variation can be responsible for trace element deficiencies and toxicities, which in turn can affect the quality of food. Plant breeding can be an important tool to both increase the concentration of desirable trace elements and reduce ...
