  In order to study yield stability of bread wheat cultivars including Alvand, Alamout, Zarrin, Navid, Azar 2, Sabalan, Omid and Bezostiya under irrigation an experiment was conducted in RCBD for three cropping seasons (2007-2010) at six locations. Simple and combined analysis of variances for three years, each location and also combined analysis of variances for 3 years and 6 locations were implemented. Lin and Binns parameter, environmental coefficient of variations and rank method were used for determination of stable cultivars. Results of combined ANOVA (three years x six locations) showed that interaction effect of year x location x genotype was significant. The highest grain yield belonged to the Alvand cultivar  with 3.74 tha -1. Results of stability analysis with Lin and Binns method also showed that Zarrin cultivar had the lowest within location variance for grain yield and lowest environmental coefficient of variations was belonged to cultivars Zarrin and Sabalan. The results of rank method showed that cultivars Alvand and Sabalan had the lowest rankingand cultivars Sabalan and Bezostiya had the lowest SDR among the experimental cultivars. It can be concluded that Zarrin and Sabalan cultivars had the highest yield stability and thus it can be recommended for locations in which it was studied. Manuscript profile

  یکی از مشکلات آنالیز پوششی داده ها (DEA) مشکل تبعیض در میان واحدهای تصمیم گیری کارآمد (DMUs) است و بنابراین، منجر به تعداد زیادی DMU به عنوان کار آمد میشود. هدف اصلی این مقاله غلبه بر این ناتوانی است. یکی از روش ها برای رتبه بندیی DMU های کارآمد به حداقل رساندن ضریب تغییرات (CV) برای ورودی-خروجی وزن میباشد. در این مقاله، یک مدا غیر خطی برای رتبه بندی DMU کارآمد مبتنی بر به حداقل رساندن انحراف مطلق میانگین وزن ها معرفی کردیم و سپس ما مدل غیر خطی به یک فرم برنامخ ریزی خطی تبدیل کردیم.

  There are more than two hundred horse breeds in the world that have different body structure, color and specific abilities depending on the geographical and weather conditions of their region. The Arabian horse, which history goes back about5 thousand years ago, has played a key role in the life history of human. Since the size of trunk region of breeds are different, biometric indices could be used to identify different breeds of horses. The present study was designed to determine the biometric indices of different trunk region were evaluated in 30 Iranian Arab horses. In this study 13 characteristics of different trunk regions were evaluated in 30 Iranian Arab horses. These horses were at least 3 years old and were selected from Kerman horse corrals. Then the mean, standard deviation, coefficient of variation and confidence interval of the characteristics were calculated. The data were compared between male and female as well as between the age groups older and younger than 8 years old by independent t-test. The results of this study showed that the gluteal height and length of lateral aspects of pelvis had the lowest and highest coefficient of variation among the measured characteristics, respectively. In this research, the characteristics were compared in different age and sex groups. This comparison showed a significant difference in the gluteal height in two different sex and age groups and length of lateral aspects of pelvis in two different age. Manuscript profile
