Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...
the new cereal, primary tritipyrum is a synthetic amphiploid derived from crossing between durum wheat varieties (triticum durum, 2n=4x=28, aabb) and wild coach grass species (thinopyrum bessarabicum, 2n=2x=14, ebeb). in this study the genotype × environment interaction effect containing change in rank and value for grain yield of seventeen genotypes including eight primary and combined primary...
Durum wheat (Triticum turgidum L.), like most other crops, is affected by various stresses. Therefore, cultivars that, in addition to the ability to produce higher yields, can maintain their yield potential in different years and locations are considered superior cultivars. In order to obtain high-yielding and stable genotypes of durum wheat, 16 lines with two control cultivars Dehdasht and Sey...
in order to study the effect of mallow weed competition and nitrogen (n) rates on grain yield and yield components of wheat cv. chamran, a field experiment was conducted in 2009. the experiment was designed as a split-plot with three replications and additive series. the n application rates were assigned in the main-plots (50, 100, 150 and 200 kg.n.ha-1) and sub-plots consisted of target common...
wheat grain yield is adversely affected by post-anthesis drought stress conditions in most wheat growing areas of iran. to evaluate the effect of late drought stress on wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of collage of agriculture, shiraz university during 2009-2010 growing season. ir...
in order to study the consequences of the application of mycorrhiza and azospirillum inoculants on yield and yield components of wheat cultivars, an experiment was conducted in the research station of shahid chamran university of ahvaz, iran in 2012-13. the experimental design was factorial based on randomized complete blocks design with three replications. the treatments including of mycorrhiz...
The stability of yield performance is one of the most desirable characters of a genotype to be released as a variety, which allows the developed varieties to be adopted in large areas. To obtain high yielding and stable durum wheat genotypes, 18 durum wheat lines and promising lines along with two commercial durum (Behrang) and bread wheat (Chamran) check cultivars were evaluated in four warm a...
Soil gravel content affects many soil physical properties, as well as crop yield. Little is known regarding the influence of soil gravel content on growth and nutrient uptake of durum wheat (Triticum durum Desf.). The accumulation of nitrogen and phosphorous during the vegetative and reproductive periods and the contribution of pre-anthesis assimilates to grain N and P content have been evaluat...
In order to evaluate the effect of different rates of nitrogen (N) and corn, rapeseed, sunflower and wheat residues on plant height, biological and grain yield and N use efficiency of wheat, an experiment was conductedduring 2010-2011 at Agricultural College of Shiraz University. The experimental design was split-split plot based on RCBD with four replications. Treatments were N (45, 90, 135 an...
Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...
