In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...

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, ...

In order to assess the relationship of grain yield and some of the agronomic traits recombinant inbred lines (RIL) population of bread wheat derived from the Roshan × Sabalan were used to detect the informative traits on grain yield as the suitable criteria for indirect selection and path coefficient analysis. Two hundred and sixty seven recombinant inbred lines with three control cultivars (Ro...

Baking quality is one of the most important traits in wheat quality breeding. In the present study, allelic diversity of the genes encoding glutenin with low molecular weight (LMW-GS) was evaluated in 15 good, average and poor cultivars in term of baking quality using SRAP markers. Further, morphological traits, including 100-seed weight, spike number per plot, seed number per spike, plant heig...

     Determining the relationships between grain yield and some yield components of wheat is most important in permanent yield production.  Using path coefficient analysis in order to determine key traits affecting majorly yield, and also to study direct and indirect effects of yield and yield components, this research was performed during 2006-2009 ys using 94 doubled-haploid (DH) lines, their...

Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...

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...
