<p>Lipoxygenase-1 (LOX-1) null 'New Sachiho Golden' is a two-row malting barley (<i>Hordeum vulgare</i> L.) cultivar released in 2015 that was developed at the Tochigi Prefectural Agricultural Experimental Station by backcross breeding using the high-yield leading cultivar 'Sachiho Golden' as a recurrent parent and the LOX-1 null mutant 'Daikei LM1' as a non-recurrent parent. To develop 'New Sachiho Golden' we used a simple LOX activity assay and marker-assisted selection. This is the first LOX-1 null malting barley cultivar in Japan that is resistant to barley yellow mosaic virus (types I–III). Agronomic characteristics and malting qualities of 'New Sachiho Golden' were similar to those of 'Sachiho Golden', except that 'New Sachiho Golden' had no LOX activity in ungerminated grains and had clearly lower LOX activity during malting than 'Sachiho Golden'. The concentrations of a <i>trans</i>-2-nonenal (T2N) precursor in wort and beer made from 'New Sachiho Golden' were significantly lower than in those made from 'Sachiho Golden', both before and after storage.</p>
