- ... Hordeum species develop a central spikelet flanked by two lateral spikelets at each inflorescence node. In ‘two‐rowed’ spikes, the central spikelet alone is fertile and sets grain, while in ‘six‐rowed’ spikes, lateral spikelets can also produce grain. Induced loss‐of‐function alleles of any of five Six‐rowed spike (VRS) genes (VRS1‐5) cause complete to intermediate gains of lateral spikelet fertil ...
