continual heat stress affects approximately 7 million hectares of wheat in developing countries, while terminal heat stress is a problem in 40% of temperate environments, which cover 36 million hectares throughout the world. heat tolerance is a quantitative and complex trait that doesn’t have much success in direct selection. for this purpose, however, a thorough understanding of physiological ...

Objective: In order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of Kermanshah Sararood Dry Land Agricultural Research Institute, located on the western part of Iran. Methods: The experimental design was a randomized lattice design with tow ...

in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...

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 ...

current study aimed at determining the most reliable drought tolerant criteria for identification of sugar beet genotypes. a split plot design based on randomized complete block design with three replications was applied at motahari research station, karaj, iran in 2012. two irrigation treatments including normal irrigation after 80-90 mm and irrigation after 270 mm evaporation (stress conditio...
