The purpose of this breeding was to obtain barley lines with extremely low polyphenol content which have great advantages in preventation of the haze formation during beer brewing and the browning of polished barley after boiling. All the breeding lines possessing proanthocyanidine-free allele ant13, ant17 or ant28 had more excellent qualities and agronomic properties than their proanthocyanidine-free parents. Among these three ant alleles, the lines possessing ant28 showed the most excellent performances both in the malt quality and agronomic properties; Daikei HL107 and Daikei HL112 with ant28 had higher yield than Mikamo Golden with the similar characteristics in the malting quality. However, all the proanthocyanidine-free breeding lines showed poor tolerance to the pre-harvest sprouting. In the further breeding of the proanthocyanidine-free barley, the improvement of the tolerance to the pre-harvest sprouting is the most important problem.
