به منظور بررسی تنوع ژنتیکی موجود برای برخی صفات زراعی و مورفولوژیک مختلف در 32 ژنوتیپ مختلف گلرنگ، آزمایشی در سال زراعی 83-84 در مزرعه تحقیقاتی دانشگاه صنعتی اصفهان در لورک نجف آباد در قالب طرح بلوک کامل تصادفی به سه تکرار اجرا شد ضمنا تنوع ژنتیکی 20 ژنوتیپ های مذکور با استفاده از نشانگر مولکولی rapd مورد بررسی قرار گرفت. در این مطالعه صفات زراعی و مورفولوژیک تعداد روز از 50 درصد سبز شدن، تعداد...
گلابی از جنس pyrus، عضوی از زیرخانواده pomoideae و خانواده rosaceae است که بعد از سیب و انگور مهمترین میوه منطقه معتدله به شمار می آید. ایران با نزدیکی به مراکز تنوع گلابی و نیز دارا بودن بیش از ده گونه از جنس pyrus به عنوان یکی از مهم ترین منابع ژنتیکی گلابی در دنیا شناخته شده است. از طرف دیگر، کشور ایران با سطح کشتی معادل 17000 هکتار و با عملکرد 114706 کیلو گرم در هکتار یکی از مراکز تولید گلا...
The genetic diversity of major crops, including durum wheat, has suffered an overall reduction with time. The knowledge of patterns of genetic diversity enhances the efficiency of germplasm conservation and improvement. In this study, 87 Iranian landraces of Triticum turgidum var. durum originating from different geographical areas of Iran, along with 21 durum cultivars from ten countries were ...
Genetic diversity among Russian olive genotypes in three different regions of East-Azerbaijan province (includes Tabriz, Maragheh and Malekan) were assessed using morphological and molecular (AFLP) markers. Results of the quantitative and qualitative traits statistics showed a significant genetic variation among studied germplasm and categorized them in five distinguished groups. The most numbe...
In order to have a sustainable management on Persian sturgeon as a highly commercial species in the South Caspian Sea, we need to identify its population structure and the level as well as its conservation status in their natural habitat. To develop a conservation program for this all Caspian Sea' sturgeon species it requires knowledge of its genetic diversity using reliable molecular marker t...
The wild mint "Mentha longifolia (L.) Hudson subsp. noeana (Briq.) Briq." is an important medicinal plant which contains several worthy components like: menthone, pulegone, pipertenon, menthol, thymol, and carvone in its essential oil. This plant grows extensively in center of Asia including Iran. Because of so worthy components and its big role in traditional and modern medicine, the wild mint...
Extended Abstract Introduction and Objective: Among the country's horse breeds, the Arabian horse has the largest population. Arabian horses are very beautiful and resistant to harsh environmental conditions and are mostly bred in the southern regions of the country. Due to the large population of this breed in the country, it has given rise to several genera that may be genetically distinct. ...

many agriculturally important traits are complex, affected by many genes and the environment. quantitative trait loci (qtl) mapping is a key tool for studying the genetic structure of complex traits in plants. in the present study qtls associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...
the kermani sheep is an important meat producing an animal in iran and its economic efficiency is mainly dependent on its growth and reproduction ability. inter-simple sequence repeat (issr) is the genome region between microsatellite loci. the aim of this study was to evaluate the association of two different issr markers with predicted breeding values (pbv) of body weight trait in kermani she...
