Outline
In order to understand the variability and stability of grain protein content in two-rowed hulled barley, 334 varieties (lines) from different sources were used as materials to determine the grain protein content under six environments. The results showed that there were significant differences in grain protein content among varieties (lines), environments, and the interaction between trial sites and varieties (lines). According to the 10-class frequency distribution rule, the protein content of grains in each environment was mainly distributed in grades 3-8, which tended to be normally distributed. By calculating the BILPs value of grain protein content and analyzing the Di value of AMMI model, two stability varieties (lines) with high protein content were selected: Zhejiang 96-6, and Huadamai 8; two stability varieties (lines) with medium protein content were selected: Chuan 52209 and Nasonijo; and two stability varieties (lines) with low protein content were selected: Qu 146V025W and 9919 (Xinjiang, China).
