in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

to study yield and its relationships with yield components in 10 varieties of foxtail millet (kfm1 to kfm10), an experiment was carried out in safiabad agricultural research center in rcbd design with three replications for a period of three years (2003 to 2005). vegetative and reproductive characteristics of each cultivar were recordered during the growing seasons. three year results showed si...
