introduction of a suitable vetch as winter crop in cold drylands of iran is highly important. line vp-2670 with origin of turkey was selected from icarda nursery during 2002 and was evaluated along with other selected lines and local checks over nine years in different stations and on-farm conditions. vp-2670 with mean 3500 kgha-1 dry biomass over environments, high stability and protein conten...

abstract to determine the effects of different levels of drought stress on yield and yield components of corn hybrids as well as to determine the correlation between the characteristic and yield in different level of stress a experimental study was done in split plot with 15 corn hybrids placed in gharakheil. the main plot was contained different levels of stress(a1:irrigation after 50mm evapor...

in order to increase drought tolerance in bread wheat, an appropriate breeding program based on inheritance of drought tolerance is recommended. in the present study, nine bread wheat cultivars and their f2 progenies were evaluated in a randomized complete block design under normal and drought stress conditions. nine sensitivity/tolerance indices were calculated for studied genotypes and stress...

in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), ...

in order to evaluate drought tolerance of some aegilops triuncialis ecotypes a factorial experiment based on a completely randomized design was conducted under non-stress and drought stress (irrigation until 50% of heading) condition in the greenhouse of mohaghegh ardabili university in 2012. drought tolerance and susceptibility indices for grain yield were calculated and principal component an...

drought is the most significant constraint for crop production in arid and semi-arid regions. in order to assess drought tolerance in fifteen rapeseed (brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of college of agriculture, shiraz university, shiraz, iran during 2009-2010 growing season. the cultivars were arranged...
