بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
the present study was designed to examine the anatomical parameters of the cardiopulmonary system, the function of venous blood gas parameters and the development of ascites incidence in two genetic line chickens. three hundred forty day-old chickens from two pure broiler breeder lines, which were different in their growth rate and susceptibility to ascites syndrome were obtained. the relative ...
To improve crop yields and increase of production performance in marginal areas, the use of genetic potential of crops in terms of morphological and physiological characteristics can lead to yield improvement and increase of production performance in areas with saline water and soil salinity. In order to evaluate genotypic variation in growth and physiological traits of different bread wheat cu...
The data on 6772 growth records of Sirohi goats maintained at All India Coordinated Research Projecton Sirohi goat at Livestock Research Station, Vallabhnagar, Udaipur, India, and recorded between 2004 and 2016, were analysed to study the growth related traits and their genetic control. The overall least squares means of body weight at birth, W3M, W6M, W9M, W12M, were 2.34 ± 0.03, 12.44 ± 0.19,...

Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...
چکیده آنالیزژنتیکی صفات رشد در بز کرکی راینی شامل وزن تولد، سه، شش و نه ماهگی با استفاده از 4117 رکورد مربوط به 204 پدر و 1402 مادرانجام شد. این رکوردها از سال 1372 تا 1385 (13 سال) جمع آوری شده بود. به منظور برازش بهترین مدل برای آنالیز ژنتیکی این صفات از مدل حیوانی چند متغیره معین و نامعین و همچنین مدل تکرارپذیری استفاده شد. اثرات ثابت شامل سن، جنس، نوع تولد، شکم زایش و اثر سال و ماه تولد، ا...
camel is a resistant species to drought and cold weather and produces milk and meat in harshest environmental condition. camel population in iran has been decreasing during last decades, and genetic studies are quite necessary for considering the conservation and productivity of this species. in this study growth hormone gene influencing growth, milk production and reproduction was considered. ...
