Variety Description

Varieties used for comparison: 'Xena' and 'Champion'

Summary: The flag leaves of 'Brahma' are longer and wider than those of 'Xena' and shorter and narrower than those of 'Champion'. The collar of 'Brahma' is cup shaped whereas it is platform shaped on 'Champion'. The spike shape of 'Brahma' is parallel whereas it is tapering in 'Champion'. The spike of 'Brahma' is longer than that of both reference varieties. The curvature of the first segment of the rachis of 'Brahma' is weak to medium whereas it is medium to strong on 'Xena'.


PLANT: two row, spring feed barley, intermediate growth habit at tillering, absent or very sparse pubescence on the lower leaf sheaths

FLAG LEAF: weak to medium pubescence on blade
FLAG LEAF SHEATH: medium glaucosity, weak pubescence
AURICLES: very weak anthocyanin colouration

SPIKE: emerges mid-season, weak to medium glaucosity, semi-erect attitude, cup shaped collar, parallel shape, lax to medium density, parallel to 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: weak anthocyanin colouration of the tips, longer than length of spike, rough spiculations on margins
FIRST SEGMENT OF RACHIS: short to medium length, weak to medium curvature

KERNEL: very weak to weak anthocyanin colouration of nerves of the lemma at beginning of ripening, whitish aleurone layer, long rachilla hairs, husk absent, absent or very weak spiculation of inner lateral nerves of dorsal side of lemma, no hairiness on ventral furrow, clasping disposition of lodicules, transverse crease basal markings, long, wide

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

Origin & Breeding History: 'Brahma' (experimental designation BZ504-125 and TR07728) originated from the cross 'Salute' / 'Xena' made near Yuma, Arizona in March, 2002 and was advanced using the standard pedigree method. The F1 was grown near Bozeman, Montana in the spring of 2002 and F2 seed was planted near Yuma in November, 2002. Single F2 spikes were selected in April, 2003, were threshed in bulk and planted as an F3 population in May, 2003 near Bozeman, Montana. Several F4 rows from this cross were selected based on plant height, straw strength and disease tolerance and were harvested in the fall of 2004. One such row was selected and designated BZ504-125. The F5 through F8 generations were tested for grain yield and other agronomic traits from 2005 through 2008. TR07728 was tested in the Canadian Two Row Barley Coop in 2007 and 2008 and was recommended for registration by the Prairie Recommending Committee for Oat and Barley in February 2009.

Tests & Trials: Tests and trials for 'Brahma' were conducted in Neapolis, Alberta during the 2008 and 2009 growing seasons. The trials were planted in a RCB design and consisted of 3 replicates of each variety, with each variety grown and replicated 4 times in each replicate. Each replicate was approximately 5 metres in length with 5 rows per replicate spaced 0.23 metres between rows. Measured characteristics were based on a minimum of 24 measurements per variety.
