Variety Description

Varieties used for comparison: 'Prosper', 'Carberry' and 'Glenn'

Summary: The lower leaf sheaths and blades of the seedlings of 'Barlow' are glabrous whereas they are pubescent on the reference varieties. The intensity of anthocyanin colouration on the flag leaf auricles of 'Barlow' is weak whereas it is medium intensity on 'Prosper'. The flag leaf blades of 'Barlow' are glabrous whereas they are pubescent on 'Prosper'. 'Barlow' heads earlier than 'Prosper'. The spike of 'Barlow' has very weak glaucosity whereas 'Carberry' has medium. The glaucosity of the culm of 'Barlow' is weak whereas it is medium on 'Prosper' and 'Carberry' and strong on 'Glenn'. The culm neck of 'Barlow' is slightly curved whereas it is straight on the reference varieties. The shape of the lower glume beak of 'Barlow' is slightly curved whereas it is straight on 'Prosper' and 'Glenn'. The kernel colour of 'Barlow' is dark red whereas it is medium red on 'Carberry'.

Origin & Breeding History: 'Barlow' (experimental designation ND809) is the result of the final cross using the modified pedigree and bulk methods made at North Dakota State University (NDSU), Fargo, North Dakota in the fall of 1999. The pedigree is ND744 ('Glenn 'S')/ND721. The F1 plants were grown in a greenhouse at NDSU in the spring of 2000. 200 spikes were selected from the F2 plants, were threshed and sent to Christchurch, New Zealand to be grown in a winter nursery as F3 head rows. In the summer of 2001, 10 spikes from the F3 were selected and advanced to the F4. In the summer of 2001, the F4 was grown and 10 spikes were selected, individually threshed and advanced as an F5 as head-rows in the winter nursery in New Zealand. In the following summer of 2002, the F6 was grown in yield trials at NDSU research farms in Casselton and Prosper, North Dakota. A selected plot from Casselton was harvested and bulked for yield trials in 2003. The F7 to F9 was tested in an Elite yield trials in 2003, 2004 and 2005. ND809 was designated at this time. The line was tested in the summers of 2006-2008 in statewide yield trials at 7 locations. It was released in January 2009. Selection criteria in the early generations included plant vigor, height, maturity and pest resistance. In later generations selection criteria included grain yield, lodging resistance, shattering resistance, test and kernel weights, disease resistance and milling and bread making qualities.

Tests & Trials: Tests and trials for 'Barlow' were conducted during the summer of 2013 in Rosebank, Manitoba. Plots consisted of seven rows with a row length of 5 metres and row spacing of 18 cm. There were 3 replicates. The tests and trials were supported by the test report purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA PVPO# 200900342.
