e0“Over 100 Brazilian hard red spring wheat cultivars released from 1986 to 2016 were evaluated for their agronomic performance in eastern Canada”
e6“The Brazilian germplasm is a valuable source of semi-dwarf ( Rht ) genes, and 75% of the Brazilian collection possessed Rht-B1b”

Other claims from this paper (9)
- Association Several Brazilian wheat cultivars were superior or statistically equal to the highest yielding Canadian checks in agronomic performance in eastern Canada.
- Observation Several Brazilian wheat cultivars had excellent resistance to leaf rust.
- Observation Only a few Brazilian wheat cultivars tested positive for Lr34 or Lr16 resistance genes.
- Observation Resistance of Brazilian wheat cultivars to stem rust and stripe rust was variable.
- Observation Many Brazilian wheat cultivars had high levels of resistance to Canadian and African Ug99 strains of stem rust.
- Observation Many Brazilian wheat cultivars had good Fusarium head blight (FHB) resistance.
- Mechanism Fusarium head blight (FHB) resistance of Brazilian wheat appears to be derived from the cultivar Frontana.
- Observation Brazilian wheat cultivars carry Rht-B1b in 75% of the Brazilian collection.
- Observation Many Brazilian wheat cultivars were genetically distinct from Canadian wheat and are a valuable resource to increase disease resistance and genetic variability in Canada.
