abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
abstract common root rot induced by bipolaris sorokiniana, is one of the most important diseases of wheat. chemical control of this disease is difficult because of it is a soil-born pathogen, so that, application of other methods is useful to reduce disease level especially resistance cultivars. in this research, were examined reaction of some wheat cultivars and lines against common root rot i...
چکیده پوسیدگی عمومی طوقه و ریشه گندم در سال های اخیر به عنوان یک بیماری مهم در استان خراسان شمالی جلب توجه نموده است. به منظور شناسایی عامل یا عوامل اصلی قارچی بیماری در سال های زراعی 86- 1385و87 - 1386 نمونه برداری هائی از مزارع گندم آبی مشکوک به بیماری درمناطق شیروان، فاروج، بجنورد، اسفراین و مانه و سملقان در سه مرحله گیاهچه، پنجه زنی تا ساقه رفتن و ظهور سنبله تا سفت شدن دانه به عمل آمد. از ب...
A PCR-based method was developed to distinguish between durum/common wheat and common wheat by leveraging slight differences of DNA sequence in Starch Synthase II (SS II) coded on wheat A, B and D genomes. A primer pair, SS II ex7-U/L, was designed to hybridize with a conserved DNA sequence region found in SS II-A, B and D genes. Another primer pair, SS II-D 1769U/1889L, was constructed to reco...
Th e objective of this paper was to show diff erences among qualitative parameters of commercially produced Slovak fi ne and wholemeal wheat fl ours prepared from Triticum aestivum L. (common wheat) and Triticum aestivum ssp. spelta L. (spelt wheat). Th e selected chemical parameters (protein, starch, ash, glucose, fructose, sucrose, maltose, pH, lactic acid, acetic acid, citric acid, succinic ...
Triticeae species have a large and complex genome, which has made it difficult to obtain their sequence data. Some alien chromosomes called the gametocidal (Gc) chromosomes introduced into common wheat can induce chromosomal breakage resulting in the generation of deletions and translocations. The induced deletions have been established as deletion stocks in common wheat. This Gc system is also...
Grain shape and size are involved in the main components of the domestication syndrome in cereals. Wheat grain shape has been dramatically altered at each stage of the domestication of tetraploid wheat and through common wheat speciation. To elucidate the evolutionary change of wheat grain shape, principal component (PC) analysis of grain shape-related traits was first conducted using wild and ...
ABSTRACT A total of 78 isolates of Puccinia triticina from durum wheat from Argentina, Chile, Ethiopia, France, Mexico, Spain and the United States and 10 representative isolates of P. triticina from common wheat from the United States were tested for virulence phenotypes on seedling plants of 35 near-isogenic lines of Thatcher wheat. Isolates with virulence on lines with leaf rust resistance g...
