Varieties used for comparison: 'AC Morgan' and 'CDC Dancer'
Summary: At the 5 to 9 tiller stage, the leaf blade pubescence of 'ORe6251M' is sparse whereas that of 'AC Morgan' is glabrous. The pubescence of the leaf sheath of 'ORe6251M' is sparse whereas it is glabrous for 'AC Morgan' and medium density for 'CDC Dancer'. 'ORe6251M' is earlier heading than both reference varieties. There are no hairs or spines on the lowest panicle node of 'ORe6251M' whereas there are a few hairs or spines for both reference varieties. The lemma of 'ORe6251M' has a weak tendency to be awned whereas the tendency is absent to very weak for both reference varieties. The kernel of 'ORe6251M' is light brown whereas it is yellow for 'AC Morgan' and cream for 'CDC Dancer'. The shape of the scutellum of 'ORe6251M' is rounded whereas it is pointed for both 'AC Morgan' and 'CDC Dancer'.
PLANT: spring hulled type, erect juvenile growth habit, sparse pubescence on lower leaf sheath and lower leaf blade
STEM: medium density of pubescence above and below the upper culm node
LEAF: light to medium green, sparse to medium density of pubescence of margin, absent or very weak glaucosity
PANICLE: equilateral/symmetrical orientation, medium density, semi-erect attitude of branches, 30 to 45 degree angle between dominant side branch and rachis, absent or very few short hairs or spines on lowest node
SPIKELET: semi-abscission separation, semi-nodding, 2 grains
LEMMA: small extent of lateral overlap on palea, white to yellow at maturity, absent to very sparse density of pubescence on lateral and dorsal surface, weak tendency to be awned
KERNEL: basal hairs absent, light brown
GROAT: dense pubescence
SCUTELLUM: rounded, medium size
AGRONOMIC CHARACTERISTICS: good resistance to lodging, good resistance to shattering
DISEASE REACTIONS: resistant to Black loose smut (Ustilago avenae) races A13, A60 and A617; moderately susceptible to Crown rust (Puccinia coronata) races CR13, CR223, CR249, CR254, CR257, CR258, CR259 and Barley yellow dwarf virus; susceptible to Crown rust (Puccinia coronata) races NGCB-94, NTGG and LQCB-91 and Stem rust (Puccinia graminis) races TGB, TGL and TJJ
Origin & Breeding History: 'ORe6251M' (experimental designation 308CM111 and OT6007) arose from the cross 'OT591' (female parent) by 'T108CM01F2' (male parent) conducted at the Oat Advantage research farm near Saskatoon, Saskatchewan in the fall of 2008. The F1 was grown from January to April 2009 with the F2 grown in bulk in a population plot during the 2009 growing season. Field selection in the F2 was based on plant type, disease resistance and grain quality. The F3 was increased in the growth cabinet in the fall of 2009 as was the F4 in the winter into 2010. The F5 seed was sown at the Saskatoon site and further selected for plant type, agronomic qualities, disease resistance, yield and visual grain quality. Seed from a subset of F5 derived F6 selected plants were sent to New Zealand in the fall of 2010 for increase. In 2011, the top performing lines were tested in yield trials in western Canada. One line, OT6007, arose out of this testing and was entered into the Western Cooperative Oat Registration Trial in 2012 and 2013.
Tests & Trials: The comparative trials for 'ORe6251M' were conducted during the 2014 and 2015 growing seasons at the research plots of Oat Advantage near Saskatoon, Saskatchewan. A three replicate design was planted using plots measuring approximately 3 metres by 1 metre with 6 rows per plot spaced 20 cm between rows. Measured characteristics were based on 20 measurements per variety per year. Disease ratings were provided through the Western Cooperative Oat Registration Trials, Disease Evaluation Team Report 2012 to 2013.
