The predicted world population increase along with climate changes threatens sustainable agricultural supply in the coming decades. It is therefore vital to understand crops diversity associated to abiotic stress response. Heat stress is considered one of the major constrains on crops productivity thus it is essential to develop new approaches for a precocious and rigorous evaluation of varieta...
Emmer tetraploid hulled wheats are considered as the ancestor of modern wheat and have considerable potential for durum wheat improvement, especially in terms of grain protein content. To investigate the response of emmer and durum wheats to different levels of nitrogen fertilizer, eight durum and four emmer genotypes were evaluated in the field during 2017 cropping season. The experiment was c...
In order to study changes in morphophysiological traits of wheat cultivars released from 1940 to 2000 in Iran and to determine the association of these traits with grain yield, an RCBD experiment was conducted with 15 wheat cultivars released during past 60 years in Arsanjan (Fars province) in 2006 and 2007. Results indicated that grain yield increased significantly during these 60 years (r=0.9...
The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...
The present study was undertaken to evaluate direct and indirect selection criteria for the improvement of grain yield and quality components in Chenopodium quinoa Willd. Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing ...
the new cereal, primary tritipyrum is a synthetic amphiploid derived from crossing between durum wheat varieties (triticum durum, 2n=4x=28, aabb) and wild coach grass species (thinopyrum bessarabicum, 2n=2x=14, ebeb). in this study the genotype × environment interaction effect containing change in rank and value for grain yield of seventeen genotypes including eight primary and combined primary...
In this study, we compared the fecal microbiota and metabolomes of 26 healthy subjects before (HS) and after (HSB) 2 months of diet intervention based on the administration of durum wheat flour and whole-grain barley pasta containing the minimum recommended daily intake (3 g) of barley β-glucans. Metabolically active bacteria were analyzed through pyrosequencing of the 16S rRNA gene and communi...
most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...
