Varieties used for comparison: 'AC Metcalfe', 'Merit' and 'Conrad'
Summary: The frequency of plants with recurved flag leaves is very low on 'ABI Voyager' whereas it is medium on 'Merit' and 'Conrad'. The intensity of anthocyanin colouration of the flag leaf auricles is very weak on 'ABI Voyager' whereas it is medium on 'Merit' and strong on 'Conrad'. The flag leaves of 'ABI Voyager' have weak glaucosity on the sheath whereas it is medium on 'Merit'. The spike attitude of 'ABI Voyager' is erect to semi-erect whereas it is horizontal in 'AC Metcalfe'. The spike collar of 'ABI Voyager' is cup shaped whereas it is platform on 'AC Metcalfe' and 'Merit'. The spike of 'ABI Voyager' is very lax to lax whereas it is dense in 'AC Metcalfe' and medium density on 'Conrad'. In the median spikelet, the glume and awn are equal in length to the grain in 'ABI Voyager' whereas the glume and awn are shorter than the grain in 'AC Metcalfe' and 'Merit'.
PLANT: two row, spring malting barley, erect growth habit at tillering, medium density of pubescence on the lower leaf sheaths, very low frequency of plants with recurved flag leaves
FLAG LEAF: weak to medium pubescence on blade
FLAG LEAF SHEATH: weak glaucosity, weak to medium density of pubescence
AURICLES: very weak intensity of anthocyanin colouration
SPIKE: emerges mid-season, very weak glaucosity, erect to semi-erect attitude, cup shaped collar, tapering to parallel shape, very lax to lax density, parallel to weakly divergent attitude of sterile spikelet, glume and awn length of the median spikelet are equal in length to the grain
LEMMA AWNS: equal to longer than length of spike, semi-smooth to rough spiculations on margins
FIRST SEGMENT OF RACHIS: short to medium length, weak to medium curvature
KERNEL: very weak anthocyanin colouration of nerves of the lemma at beginning of ripening, whitish aleurone layer, long rachilla hairs, husk present, weak spiculation of inner lateral nerves of dorsal side of lemma, weak hairiness on ventral furrow, frontal disposition of lodicules, horseshoe to transverse crease basal markings, medium length and width
AGRONOMY: good resistance to lodging, fair tolerance to straw breakage
Origin & Breeding History: 'ABI Voyager' (experimental designation 2B03-3719 and TR09402) was derived from the cross between '2B96-5038' and '2B97-4796' conducted in the spring of 2000 in Fort Collins, Colorado. The F1 generation was increased in the greenhouse during the fall of 2000, followed by an F2 population in Idaho Falls, Idaho in the spring of 2001 and an F3 single seed descent generation in the greenhouse during the winter/spring of 2001/02. A total of 43 F4 head rows were planted in Idaho Falls in the spring of 2002. One of six rows, identified as 043-097, was selected and increased in Christchurch, New Zealand and advanced to Y1. The single F5 row selection was assigned the experimental number, 2B03-3719, and was entered into replicated performance testing in the spring of 2003. Selection criteria include yield, maturity, straw strength, and malting quality traits. In 2008 and 2009, 'ABI Voyager' was entered in the Western Spring Barley Nursery regional performance nurseries. In 2007 and 2008, the line was entered into regional trials. In 2009, it was entered into the Canadian Western Two-Row Barley Cooperative Registration Trials as TR09402.
Tests & Trials: Tests and trials for 'ABI Voyager' were conducted in Minto, Manitoba during the 2011 and 2012 growing seasons. The trials consisted of 4 replicates per variety in a RCB design. Each replication consisted of 5 rows, measuring approximately 5 metres in length by 1 metre wide. Measured characteristics were based on a minimum of 15 measurements in 2011 and 20 measurements in 2012.
