genotype by environment interaction is one of the most important subjects in crop improvement, so that different statistical measures have been proposed to estimate this interaction. in the present study, nine varieties and hybrids of spring rapeseed were evaluated in five warm dryland areas including sarpol-e-zahab, gonbad, gachsaran, pol-e-dukhtar and masjedsoliman in two growing seasons 2002...

the interaction of genotype × environment effect, because of disordering effect on genotypes selection has special importance in plant breeding programs. therefore to better selection, yield and yield stability might be considered simultaneously. in order to study of grain yield stability and the evaluation of different selection methods efficiency, 18 advanced barely lines were studied in four...

drought stress due to water deficit and terminal temperatures is a serious problem in agriculture, and it is one of the most important factors contributing to crop yield loss. to evaluate drought tolerance of barley, 12 advanced barley genotypes were studied in two rainfed and irrigated conditions (in a subtropical region, gachsaran) in 2006-2007 in a rcb design with three replications. results...

Aim and scope: The most important complications after colorectal surgery is pain which use of nonpharmacologic methods to reduce the complications has been considered by researchers. This study was conducted aiming at study on effect of Pelvic-floor muscle (PFM) exercises on Severity of pain after colorectal surgery. Materials and methods: this study is a randomized clinical trial; the statist...

the conventional approach to seismic data analysis consists of two main steps: estimating seismic velocities, (the subsurface macro-model), and seismic imaging, (mapping of the reflected seismic energy to the reflector positions). the aim and the major challenge in the seismic data analysis is the construction of the best undistorted image. this challenge would be more problematic when geometri...

background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...
