Soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. The identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. The data obtained from 75 families produced by crossi...
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...
to study the effect of biofertilizers and manure on yield and yield components of barley (hordeum vulgare) an experiment was conducted at research farm of university of zabol, iran in 2012 cropping season. experimental treatments were arranged in a factorial design based on a randomized complete block design with three replications. treatments were three manure levels (control, 20 ton/h-1, 30 t...
This study was carried out to determine grain yield and components of five bread wheat genotypes 20 advanced lines at K?rklareli Tekirda? locations in 2017-2018 cropping year. The experiments were arranged a randomized complete block design with four replications. In the study, (GY), plant height (PH), spike length (SL), number spikelets/spike (SS), grains/spike (KS), weight/spike (KWS), test w...
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...

475 Abstract: The interactive effects of vernalization, photoperiod and light intensity on the length of the apex or spike and main shoot, and the diameter of the main shoot of five different wheat (Triticum aestivum L.) cultivars (Çukurova-86, Atay-85, Lancer, Haymana79 and Bezostaya-1) having different biological characters were investigated. The research was carried out in four independent e...
In order to analyze variation and find an efficient selection approach, we used crossing results between two wheat cultivars, Azar2 and 87-Zhong291. F3 plants (374 lines) and four check cultivars planted in the form of augmented experiment. For germination, seeds were irrigated once. After using multiple statistics methods such as cluster analysis, 79 different lines were selected and used for ...
Structural comparisons between bacteriophage PRD1 and adenovirus have revealed an evolutionary relationship that has contributed significantly to current ideas on virus phylogeny. However, the structural organization of the receptor-binding spike complex and how the different symmetry mismatches are mediated between the spike-complex proteins are not clear. We determined the architecture of the...
