Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...

Despite its economic importance, not much information exists on growth and productivity of durum wheat in Iran and Isfahan. In order to evaluate growth, grain yield, and attributes in three durum wheat genotypes, Osta/Gata, Dipper-6, and PI40100, with five planting densities of 200, 275, 350, 425 and 500 seeds/m2, a four-replicate RCBD field study with a spilt-plot layout was carried out in win...
In order to study the physiological and morphological characteristics of canola cultivars at different planting dates, an experiment was carried out in 2008-2009 at the Agriculture Research Station of Yasouj. A factorial with Randomized Complete Block Design with four replications was conducted. Four planting dates (September 12, September 22, October 2 and October 12) and four cultivars (Zarfa...
A generation mean analysis was conducted to study genetic of yield and yield related traits of bread wheat in drought stress condition. In this research F1, F2, BC1 and BC2 generations were developed created using Kavir and Roushan as parents. The generations and parents were evaluated in a randomized complete block design with three replications and the traits including yield, flag leaf area, ...
This experiment was conducted to determine the effects of time and rate of nitrogen fertilizer (urea) application on yield and yield components and quality of sunflower (Helianthus annuus L. )cv.Euroflor. A field experiment was carried out at College of Agriculture, Shiraz University during Summer 2009. The experimental design was a factorial based on a randomized complete block design with 3 ...
this study was aimed at evaluating the effects of planting’s different dates on the trend of leaf area index, dry biomass weight and panicle weight in addition to the yield of rice varieties for one year in the north region of khuzestan, as spilt plots in the form of fully random blocks in three repetitions. main factor was the date of planting at three levels (26 may, 10 jun, 26 jun) and the s...
an experiment was conducted as a split plot based on complete randomized block design with three replications in the fall of 2010 at the farm of lorestan university, khorramabad, iran. four winter wheat cultivars (marvdasht, azar, shiraz and line m-79-7) as the main plot and levels of iron oxide nanoparticles (ion) along with control treatment were the subplot. iron fertilizer spraying was done...
The rice plant need the silicon element more than other nutrition elements, but its importance has not been clearly known. In order to study of silicon effect on the growth and yield of rice (Tarom Hashemi variety), an experiment was carried out in pot and field conditions with three replicates in the greenhouse and in the field of Rice Research Institute of Iran (Amol) in 2009 and 2010. Three...
An experiment was carried out to study the variability of leaf anatomical characters of wheat (Triticum aestivum L.) cultivars and their association with grain yields. Results indicated that in most of the cases cultivar differences were significant. In respect of 6th leaf anatomical characters, simple correlation coefficients indicated that most of the leaf anatomical traits had significant ne...
