 Luoma is a reduced awned winter triticale adapted to the dark brown and black soils of the Canadian prairie provinces.

Luoma was tested as WT004 in the winter rye and triticale Co-op trial and in the Field Crop Development Centre (FCDC) trials as 94D024001 and is derived from the cross 92A003/2/81DE01012/87A076 /3/Pika /4/88DL01 produced at the FCDC in 1994. 92A003 and 87A076 were winter triticale germplasm introductions from Oregon. 81DE01012 is a sister line to the winter triticale Pika and 88DL01 is the original reduced awn (awnletted) winter triticale population from which the winter triticale Bobcat was selected. The awnletted characteristic in 88DL01 came from a triticale x spring wheat cross (RL4137) back-crossed several times to spring and winter triticale.

Luoma is an awnletted (reduced awn expression) standard height winter triticale line intended for use as a feed grain, conserved forage, grazing and potentially for industrial utilization for biomass (ethanol) and fibre production. This line is 10% higher yielding, 15% higher winter survival, 1.1 kg higher for test weight, 3 mg higher for kernel weight than the check variety Bobcat and is intermediate to the checks for lodging resistance. Luoma is intermediate between the two check cultivars for falling number. Disease data indicates that Luoma is similar to the check cultivars for ergot as well as leaf and stem rust resistance.

End Use

  • Luoma is an awnletted (reduced awn expression) standard height winter triticale line intended for use as a feed grain, conserved forage, grazing and potentially for industrial utilization for biomass (ethanol) and fibre production.
Strengths
  • Luoma yields equivalent to Pika with reduced awn expression similar to Bobcat and superior winter hardiness to Bobcat.
  • Luoma has higher biomass yields than Bobcat with improved test weight and kernel weight.
  • Luoma is intermediate between the two checks (Bobcat and Pika) for lodging resistance and falling number.
Neutral Traits
  • Luoma is similar to current varieties for ergot infestation as well as leaf and stem rust resistance.
Weaknesses
  • Luoma has a slightly lower winter hardiness than Pika and a slightly lower falling number than Bobcat.
