Grain texture: A negative in either Pina or Pinb results in hard texture. Both positives results in soft.

Gluten strength: Glu-D1 2+12 associated with weak gluten, Glu-D1 5+10 associated with strong gluten.

Waxy endosperm: One negative Wx allele is sufficient for a partial Waxy phenotype.

Grain protein: Positive indicates the presence of the T. diccocoides allele for high grain protein content.

Lr37/Yr17/Sr38: Positive indicates presence of the 2NS/2AS translocation carrying this set of three resistance genes.

Hessian fly resistance: Positive indicates presence of the H9 allele.

Leaf rust resistance: Positive indicates presence of the Lr21 allele.

Stripe rust, high temperature adult plant (HTAP) resistance: The 172 - 272 haplotype is associated to the resistant allele of Stephens.

Aluminum tolerance: T indicates the presence of the Atlas tolerant allele, S indicates susceptible genotype.

VRN: One dominant allele at any of the three loci is sufficient for a dominant spring growth habit.

Dwarfing genes Rht-1: The a allele is for tall, and the b allele is for semi-dwarf.

Drought tolerance: The presence of the 1RS translocation on 1AL or 1BL enhances drought tolerance.
