Abstract: In order to understand the effects of environment on grain characters related with malting quality, including grain length, width, thickness, 1 000-grain weight and grain protein content were evaluated among 10 barley varieties which grown in 6 locations. The differences in varieties and locations and the correlation coefficients among five grain characters were studied. The results showed that the differences in grain length, width, thickness and 1 000-grain weight were highly significant among varieties and trial locations. The difference in protein content was highly significant among trial locations, while it was not significant among varieties.

Key words: environment, barley, grain character
