Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

Understanding the variability of pedological properties as well as the soil quality attributes on different landscape positions in hummocky terrains would result in a better land management in such areas. Despite the importance of such studies, no research has been couducted on the landscape-scale variability of soil quality indices in Iran and most researchers have so far focussed on pedologic...

Geometallurgy tries to predict the instability the behavior of ores caused by variability in the geological settings, and to optimize the mineral value chain. Understanding the ore variability and subsequently the process response are considered to be the most important functions of an accurate geometallurgical study. In this paper, the geometallurgical index is presented as a new tool to...

Background & aim: Pelvic shape has important effects on obstetrical outcomes. Therefore, this study aimed to determine the etiologic factors that contribute to the formation of female pelvis and describe its variability. Methods: This study was conducted on 131 women referring to Saint Joseph Hospital, Marseille...

soil alkalinity and salinity are serious problems in arid and semi-arid regions, and therefore monitoring of soil ph and electrical conductivity (ec) is necessary in any region. the present study aimed to properly interpolate soil ph and ec as soil quality indices in a semi-arid mountainous area with annual precipitation of 342.4 mm. the study area is the karimabad rangelands in hamadan provinc...

genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. in this study, r-rap, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of aegilops sp. originating from different geographical regions of iran. the 15 r-rap primer combinations revealed a total of 338 bands ranging ...
