Influence of the genotype and environment on β-glucan content of hulless barley

Hulless barley is the typical crop in Qinghai-Tibet Plateau. In order to understand the effect of genotype, environment and their interactive effects on 茁-glucans content of hulless barley, 5 hulless barley cultivars, Kunlun 12, Zangqing 25, Aqing 6, Ganqing 5 and Kangqing 6 respectively from Xining, Lhasa, Shangri-La, Hezuo and Maerkang were selected. The influence of genotype, environment and their interactive effects on β-glucan content were analyzed. The results showed that both genotype and environment had influence on β-glucan content. Average β-glucan content of cultivars from Lhasa was the highest among all selected cultivars, whereas the β-glucan content of Ganqing 5 was the highest with 3.567%.
