abstract water deficit is a major problem for the successful production of agricultural products in iran. this research was conducted to evaluate drought tolerance indices and identifying drought tolerant cultivars of canola. twenty eight canola cultivars were sassed implementing complete block designs experiments in normal and drought stress conditions at isfahan university of technology resea...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

salvia genus has 58 annual and perennial herbaceous species in iran that 17 species are endemic and salvia sahendica boiss & buhse is one of them. in order to investigate the effects of drought stress caused by peg 6000 and salinity stress induced by nacl on germination factors of salvia sahendica, two experiments were carried out based on a completely randomized design with 3 replications. in ...

in order to evaluate and drought tolerance selection in cowpea genotypes and to identify the best indices for drought tolerance, an experiment was conducted at research field university of tehran in karaj during 2011-2012 growing season. in this study, 31 cowpea genotypes were evaluated in a randomized complete block design (rcbd) with three replications under normal irrigation (non- stress) an...

breeding for environmental stress is one of the most important goals in plant breeding. among stresses, drought stress has high influencing on limitation of wheat production. so, in order to find the best drought tolerant genotypes, 24 genotypes were planted in three separate experiments in ardebil: one with optimum irrigation (control), another with water stress at pre-anthesis stage and the o...

drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...

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...
