Busby

Barley

Variety Description

Variety used for comparison: 'Seebe'

Summary: 'Busby' has strong intensity of anthocyanin colouration on the auricles of the flag leaves whereas it is very strong in 'Seebe'. The spike emergence of 'Busby' tends to be earlier than 'Seebe'. 'Busby' has a medium intensity colouration of the tips of the lemma awns whereas it is strong in 'Seebe'. The flag leaf of 'Busby' is narrower than 'Seebe'. 'Busby' has a medium frequency of plants with recurved flag leaves whereas it is high in 'Seebe'. The spike of 'Busby' is recurved whereas it is horizontal in 'Seebe'.

Description:

PLANT: two row, spring feed barley, semi-erect juvenile growth habit, absent or very sparse pubescence on the sheaths of the lower leaves

FLAG LEAF: medium frequency of plants with recurved flag leaves, weak pubescence
FLAG LEAF SHEATH: medium glaucosity, weak pubescence
AURICLES: strong anthocyanin colouration, weak pubescence on the margins

SPIKE: early spike emergence, platform shaped collar, medium anthocyanin colouration of the tips of the lemma awns, recurved attitude, weak glaucosity, parallel shape, medium density, divergent attitude of sterile spikelet, the length of the glume and its awn of the median spikelet is equal relative to the grain
FIRST SEGMENT OF RACHIS: medium length, absent or very weak curvature
LEMMA AWNS: longer relative to the spike, rough spiculations on margins

KERNEL: absent or very weak anthocyanin colouration of nerves of the lemma at beginning of ripening, whitish aleurone layer, husk present, long rachilla hair, absent or very weak spiculation of inner lateral nerves of dorsal side of lemma, no hairiness on ventral furrow, medium length, medium width

AGRONOMY: good resistance to lodging, good resistance to shattering, good tolerance to straw breakage, fair tolerance to drought

Origin & Breeding History: 'Busby' (experimental designations H94034003 and TR06673) was developed at the Field Crop Development Center, Lacombe, Alberta using a modified bulk pedigree system. It arose from the cross H93089(F1)/Seebe in 1994. The line H94034003 was selected from the F7 head rows to be grown in yield trails from 2001 to 2007. It was further tested as TR06673 in the Western Two Row Barley Cooperative Test in 2006 and 2007. The selection criteria included grain yield, test weight, 1000 kernel weight, lodging resistance, disease resistance and maturity.

Tests & Trials: Tests and trials were conducted during the summers of 2008 and 2009 in Lacombe, Alberta. Plots consisted of 8 rows with a row spacing of 0.14 meters and a row length of 2.5 meters. There were 3 replicates.
