to evaluate the agronomic characteristics in three brassica species (rape, indian mustard, and turnip) and to determine the best stress tolerance indices, 16 brassica cultivars were studied under controlled conditions in -0.6 mpa of stress and as well under field (either stressed or irrigated) conditions at the dryland agricultural research station, kermanshah during 2004-05. the results showed...

in order to study of drought tolerance in bread wheat genotypes, this study was conducted in maragheh dryland agricultural research station. the study included two experiments and the statistical design of each experiment was a rcbd with four replications, and 20 bread wheat genotypes that were compared under drought stress (rainfed) and supplementary irrigation. analysis of simple variance sup...

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. in present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°c on 12 rice cultivars (including champa yasouj, gerde, lenjan askari, kaamfirouz, kohsar, shafagh, domsiya mamassani, dular, gharib, hasan saraei, mosa tarom and 304)...

salinity problem is continuously increasing in the arid and semi-arid regions of iran. to effectively utilize germplasm resources in breeding, it is necessary to characterize and evaluate genotypes for the desirable traits and as well for salinity tolerance. salinity tolerance of 80 wheat landraces from different parts of iran was studied in two steps. at first, the degree of salnity tolerance ...
