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 creation of salt-tolerant wheat genotypes can provide a basis for sustainable production in areas that are particularly sensitive to the impacts climate change on soil salinity. This study aimed select could serve as genetic resource breeding salinity tolerance. A two-year experiment was established with 27 genotypes, grown stress and non-stress conditions. Agronomic parameters (plant heigh...

Wheat is one of the most important sources food worldwide. A selection index helps in making decisions and permits exploitation information on correlated traits to improve yields. Two cycles pedigree based desired-genetic-gain were imposed identify best isolate promising lines. The base population was composed 120 families bread wheat F6 generation. Eight combinations constructed from six trait...

Purpose and Objectives. The purpose was to evaluate the breeding value homeostaticity of grain weight number per spike in modern Ukrainian Western European winter bread wheat varieties identify adapted Eastern Forest-Steppe Ukraine sources strong expression these traits.
 Materials Methods. Twenty-eight short-stemmed (Triticum aestivum L.) accessions from three countries - fourteen accessi...

Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cut-off conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16 in College of Agricultu...

Wheat is mostly cultivated at rainfed condition in Iran, so, water deficit stress has much effect on yield reduction. Hence, breeding activities are necessary for introduction of wheat tolerant genotypes to water deficit stress. In order to estimate the heritability and genetic correlation between traits of 36 wheat genotypes, an experiment was conducted in two separate conditions (water stress...

In order to evaluate the morpho-physiological and biochemical responses of six wheat (Triticum aestivum L.) cultivars to late season water deficit stress, this experiment was carried out in controlled conditions at College of Agriculture of Shiraz University, Shiraz, Iran during 2013-14. The experimental treatments were water deficit (50 and 100% F.C.) and wheat cultivars (Sirvan, Chamran, Shir...
