To make an efficient and laborsaving quality selection in a malting barley breeding program, the relationship between malting quality parameters and the hardness index (HI) measured by Single Kernel Characterization System (SKCS) 4100 was studied with barley genetic resources and a group of descendant lines from “Yon Rkei 1363” that possess the high lysine allele lys1 and a very high diastatic power (DP). There was a highly significant correlation between the grain HI and the malt extract both in the genetic resources (r = −0.48 ** ) and in the lys1 parent‐derived lines (r = −0.50 ** ). Malt HI showed a highly significant correlation with malt extract (r = −0.70 ** in genetic resources, r = −0.57 ** in the lys1 parent‐derived lines) and malt total protein (r = 0.73 ** , 0.84 ** , respectively). For the selection of very high DP lines from the lys1 parent‐derived group, high grain HI selection was effective as all the very high DP lines had much harder grain characteristics. Therefore SKCS was regarded as a useful tool for quality selection in malting barley breeding.
