Variety Description

Varieties used for comparison: 'CDC Kendall' and 'AC Metcalfe'

Summary: 'CDC Kindersley' has a narrower flag leaf than the reference varieties. The intensity of the anthocyanin colouration of the tips of the lemma awns in 'CDC Kindersley' is strong while it is weak to medium in 'AC Metcalfe'.

Description:

PLANT: two row, spring malting barley, semi-erect to intermediate growth habit at tillering, very sparse to sparse pubescence on the lower leaf sheaths, low to medium frequency of plants with recurved flag leaves

AURICLES: medium to strong intensity of anthocyanin colouration, weak pubescence on the margins
FLAG LEAF SHEATH: medium to strong glaucosity, weak pubescence
FLAG LEAF: medium pubescence on blade

SPIKE: early to mid-season emergence, medium to strong glaucosity, semi-erect attitude, v-shaped to platform shaped collar, parallel shape, dense, divergent attitude of sterile spikelet, glume and awn of the median spikelet is equal in length to the grain
FIRST SEGMENT OF RACHIS: short, medium curvature
LEMMA AWNS: strong anthocyanin colouration of the tips, longer than length of spike, rough spiculations on margins

KERNEL: absent to very weak intensity of anthocyanin colouration of nerves of the lemma at the end of anthesis, whitish aleurone layer, long rachilla hairs, husk present, weak spiculation of inner lateral nerves of dorsal side of lemma, hairiness of ventral furrow absent, clasping disposition of lodicules, horseshoe shape of basal markings, long, wide

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

Origin & Breeding History: 'CDC Kindersley' (experimental designations TR07114, SM05409) originated from the cross 'SM00490' / 'BM9674D-64' made under glass at the Crop Development Centre (CDC) in 2001 using the pedigree breeding system. 'SM00490' is a two-row hulled barley breeding line that originated from the cross SM94319 / Iona. BM9674D-64 is a two-row hulled barley breeding line that originated from the cross TR251 / CDC Kendall. The F1 thru F4 generations were grown as bulk populations with the F1 and F3 generations being grown in winter nurseries in New Zealand. It was then grown and selected as a single F4 derived F5 row plot in Saskatoon in 2004. The seed from the F5 row plot was bulked as the line that became 'SM05409'. It was tested in CDC yield trials in 2005 and 2006 followed by testing in the Western Canadian 2-row Barley Cooperative Trials as 'TR07114' during the years 2007 and 2008. Selection criteria included high grain yield potential, good kernel quality including high test weight, good to acceptable malting profile including low grain protein, early maturity, short straw and resistance to surface borne smuts.

Tests & Trials: Tests and Trials were conducted in 2010 and 2011 at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan. Plots consisted of 5 rows with a row length of 3.66 meters and a row spacing of 0.2 meters. There were 2 replicates in 2010 and 3 replicates in 2011 arranged in a RCB design each year.
