Estimation of genetic trends is necessary to monitor and evaluate selection programs. The objective of this study was to estimate the genetic trends for milk yield in Iranian Holsteins cows using random regression test day model. Data set was consisted of 743205 test-day records from 1991 to 2008, which were collected by the Animal Breeding Centre of Iran. Breeding, environmental and phenotypic...

The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...

Study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. In the present study, genetic diversity among and within 15 Iranian native Ajowan(Carum copticum L.) populations were determined using inter simple sequence repeat (ISSR) markers. Twelve selected primers produced 153 discernible bands, with 93 (60.78%) being ...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

background: the aim of this study was to examine the interaction of dietary food groups and genetic variants of apoa1/apoc3, relative to metabolic syndrome (mets) risk in adults. methods: in this matched nested case-control study, 414 mets subjects and 414 controls were selected from among participants of tehran lipid and glucose study. dietary intake was assessed with the use of a valid and re...

asthma is considered as a chronic inflammatory airway disease and defined as increased tracheobronchial responsiveness to variety of stimuli. edema and inflammatory cell infiltration in airway is observed in the asthmatic patients. one of the essential changes in inflammation is adhesion of leukocyte to endothelium and transmigration of leukocytes to the sites of inflammation. unfortunately, li...

objective(s): asthma results from the interaction between genetic and environmental factors. adam33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. materials and methods: this is a case-control study, where four snps s1 (rs3918396), t1 (rs2280091), t2 (rs2280090), v4 (rs2787094) of adam33 gene have been assessed in patients with allergic asthma and normal cont...
