`Abstract

 

Macro and micro nutrients are essential for human health and growth development. It is reported that about three million people are suffering from nutrient deficiencies all over the world. Various sources are available like: vegetables, fruits, fish, meat and cereals to overcome these deficiencies. Among cereals, wheat and barley are main source to meet the requirement of this dietary element. Two year studies were conducted to investigate the Se concentration in grains of different wheat (T. aestivum L., T. turgidum L. and T. durum L.) and barley (H. spontaneum L. and H. vulgare L.) species originated from different parts of the world. Results indicated that the durum and emmer wheat grains contain higher Se level in both studied years (70.5 and 72.9μg kg^-1 in 2012 and 74.1 and 73.2 μg kg^-1 in 2013 respectively). Among H. spontaneum L. collected from six populations, Mahola population of barley showed remarkable variations in grain Se concentration ranged from 88.3-437.2 and 90.2-439.5μg kg^-1 in 2012 and 2013 respectively. The information obtained from the findings helps in identifying the lines of wild barley that have more Se uptake and accumulation capability. According to the conclusion of the study that H. Spontaneum L. had greater genetic variation for Se as compare to other species of wheat and barley.
