line n-78-14 with the pedigree of sha4/chil cm91099-25y-om-3n-1y-oyz-o10m-oy-3m-o10 was obtained from cimmyt, mexico in 1996 through high rainfall wheat screening nursery. preliminary evaluation of the genotypes in international nursery in gorgan and sari research stations during 1996-97 cropping season, resulted in selection of this line as one of the most high yielding genotypes. selected lin...

background & aim: despite valuable medicinal properties of safflower, breeding new varieties and development of the crop culture area has been limited due to the lack of genetic variation for some crucial characteristics as resistance to diseases and pests like safflower fly. in this study, populations of wild safflower, c. oxyacanthus were collected from western, central and southern regio...

conclusions methicillin resistance is a specialized concern in clinical studies, and it is mandatory to detect this mechanism by an accurate method that is updated periodically. increasing the resistance of s. aureus to multiple antibiotics underlines the need for intermittent resistance surveillance. results methicillin resistance was detected in 38% of s. aureus isolates, confirmed by the aga...

eight promising lines of bread wheat which had been selected through the preliminary and advanced traits, together with two check cultivar shiroudi and tajan were evaluated for yield, adabtability and response to cereal diseases in an on farm experiment conducted in two sites in moghan. combined analysis of variance on yield and yield components showed significant differences of lines in yield ...
