Characterization And Genetic Diversityof Hull-less Barley

Hull-less barley(Hordeum vugare L.)is one of the most important crops in China.Recently,there has been intense active research and interest in hull-less barley,due to its unique nutritional characteristics.However the information of systematic research on husk less barley is limited due to the wide varieties.Besides,the scientific guidance and standardization for the quality of products is unclear.In this study,the characterization of barley and their genetic diversities were investigated,including the content of protein,starch,ash,fat,dietary fiber,?-glucan,vitamin and the characterization of genetic background.We get four main results in this paper.Firstly,we get that the three varieties in Shangri-La have the lowest genetic variation coefficient in all the samples.Meanwhile the genetic variation of YunQing-2compared to other samples is high,which means that it has significant genetic diversity to other samples.Thus it can be used as the main variety for further study.Secondly,we find that Hull-less barley is rich in protein,vitamin and dietary fiber,while low in fat and sugar.Its nutritional characteristics are consistent with the objective of the modern nutriology.Thirdly,there are significant differences in the content of protein and fats between different Hull-less barleys,while small differences in the content of minerals,dietary fiber and starch.Precisely,there are significant differences in the content of ?-glucan,vitamin E and vitamin B3.Finally,we find that the varieties of Nanlong Wagner and Qinghai Yellow winter contain the highest content of dietary fiber in all the samples with no significant difference.Hence they can be used as the presentation of production withhigh dairy fiber.
