e0“Loose x loose crosses were all loose”
t0“ERAGROSTIS TEF”
e1“All the results showed a disomic inheritance pattern for all three traits which indicates that teff is an allotetraploid”
e2“the seed color genotypes of the parents were determined to be Fesho = BBB2B2, Trotteriana = BBb2('gy)b2('gy), Bursa = bbb2('gy)b2('gy) and Kay Murri bbb2b2('.)”

Other claims from this paper (19)
- Observation Four gene pairs were involved in lemma color inheritance.
- Observation Lemma color inheritance showed dominance, complementary, and epistatic interactions.
- Observation The four parental cultivars were assigned distinct lemma color genotypes.
- Observation Duplicate gene pairs governed seed color.
- Observation Seed color genes showed simple dominance with additive effects.
- Observation Fesho crosses with Kay Murri and Bursa segregated 15 brown to 1 white.
- Observation Fesho crosses with Trotteriana segregated 3 brown to 1 white.
- Observation Parental seed color genotypes were determined.
- Observation Panicle looseness was conditioned by duplicate gene pairs and branching by another pair.
- Observation Loose by compact crosses segregated 15 loose to 1 compact, indicating duplicate dominance.
- Observation Compact by compact crosses were all compact.
- Observation Branching pattern segregated 13 multilateral to 3 unilateral, suggesting recessive suppression.
- Observation Only Bursa had unilateral branching.
- Observation The authors adopted effusum, contractum and compactum for panicle forms.
- Observation The parental cultivars were assigned panicle looseness and branching genotypes.
- Observation No maternal effects were detected.
- Observation No linkage was detected.
- Observation All three traits showed disomic inheritance, indicating allotetraploidy.
- Observation The authors infer that diploid quantitative genetic theory applies to teff.
