in order to study the effects of planting systems on quantitative and qualitative characteristics of some onion genotypes, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in behbahan agriculture research station for two years (2012-2014). in this study two planting systems: onion set and transplant were assigned to main plots a...

in this study test-day records of milk (kg), fat (g), and protein (g) yields, somatic cell score (scs, cells/ml) collected by animal breeding center of iran during 2007 and 2009 were used to estimate genetic parameters using random regression model. models with different order of legendre polynomials were compared using bayesian information criterion (bic).for milk, fat yield and scs genetic an...

drought causes significant reductions in crop productivity in many parts of the world, including iran. identifying genotypes tolerant to drought stress is therefore one of the foremost goals of crop breeding programs. this study investigated the effect of terminal drought stress on yield and yield components of new winter rapeseed lines, and identified new winter rapeseed lines tolerant to term...
