Variety Description

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

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

Origin & Breeding History: 'Prosper' (experimental designation ND808) 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 1997. The pedigree is ND2857/Dapps. The F1 plants were grown in a greenhouse at NDSU in the spring of 1998. The F2 to F5 were selected, threshed individually and advanced. In the fall 2000 to spring 2001, the F5:6 generation was advanced and increased in a winter nursery in Christchurch, New Zealand and was harvested in bulk. In the summer of 2001, the F7 was grown in intermediate yield trials at NDSU research farms in Casselton and Prosper, North Dakota. Four spikes from a selected plot from Casselton were harvested, threshed separately and sent to New Zealand for purification and seed increase. The F7:8 were harvested in bulk and sent for yield trials in 2003. The F9 to F11 were tested in Elite yield trials in 2002, 2003 and 2004. ND808 was designated at this time. The line was tested in the summers of 2005-2010 in statewide yield trials at 7 locations. It was released in January 2011. 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 'Prosper' 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# 201100402.
