Nutritional imbalance and starch properties of the most crop species are mostly affected by the change of soil environment. This study was conducted to evaluate the effect of environmental conditions on nutritional (dietary elements) and microelement changes in barley grain. Barley grain is composed abundant amount of carbohydrates, proteins, vitamins and minerals along with, it is particularly good source of dietary fiber, Fe, Cu, Mn and Se for human food source and animal feed but mostly affected due acute changes in environmental conditions such as soil, water salt and cold stress. For screening and evaluation purpose, thirty three Tibetan (Tibetan) barley accessions were collected from the extremely cold region of China (Tibet) and were studied to evaluate availability and variability of microelements: Fe, Zn, Mn, Se, Cu with amylose and amylopectin ratio at the experimental site of Northwest Agriculture and Forestry University, Yangling, China during 2012 to 2013. Results indicate TB-4406, TB-664 and TB-3835 performed very well in nutritional compatibility and trace elements as compared to other thirty accessions. Among all rest thirty accessions, TB-4406 showed great performance for all five trace elements with 84.8μg kg-1, 63.4, 51.0, 40.0 and 9.37 mg kg-1 concentration for Se, Fe, Zn, Mn and Cu respectively followed by TB-664 and TB-3835. Furthermore, the findings revealed that Tibetan barley is a highly auspicious resource for genetic diversity with higher amylose contents and nutritional value of dietary elements. It is concluded that the Tibetan barley has the potential to increase microelements and carbohydrates availability could be considered as a genetic source for barley breeding program.
