Viewed : 324 - Downloaded : 192 The relationship between electrophretic band/band patterns of seed storage protein (hordein) and malt quality criteria was investigated by using 28 barley cultivars. 19 different band patterns and 45 bands belong to this patterns were identified in the cultivars. It was detected that 28 cultivars examined in this study showed significant differences (p<0.01) in terms of each malt quality criteria. Differences between the means of malting quality criteria of some cultivars which had different hordein band patterns were non-significant. Cluster analysis based on highly effective criteria on malt quality showed that the cultivars having various band patterns were in the same groups, while the cultivars having same band pattern were in different groups. Therefore, it can be concluded that there is no correlation between hordein band patterns and malt quality. Relationship between every hordein band and malt quality criteria was determined based on significance of the main differences of means among cultivars. The relationship between absence or presence of hordein band and malt quality criteria such as humidity with 3, malt extract with 8, soluble nitrogen with 9, kolbach index with 3, viscosity with 20, friability with 20 and protein with 11 was shown significant. These hordein band patterns can be used in to account as an indicator of high or low malt quality criteria. Keywords : Barley, hordein, malting quality, electrophrogram
