Other claims from this paper (17)
- Association Resistance was associated with testa phenotype.
- Association Resistance was not associated with embryo phenotype.
- Observation A was completely dominant over a for resistance.
- Association Wrinkled seed form did not diminish resistance when A was dominant.
- Association Green cotyledons did not diminish resistance when A was dominant.
- Association The r recessive allele diminished resistance in seeds borne on white-flowering plants.
- Association The i recessive allele diminished resistance in seeds borne on white-flowering plants.
- Association Seed rot resistance was closely associated with testa proanthocyanidins.
- Association Seed rot resistance was closely associated with testa sclerenchyma.
- Observation A testas lacking anthocyanins but containing PAs and sclerenchyma had high seed rot resistance.
- Association A mutation removing PAs and sclerenchyma near the hilum markedly increased susceptibility.
- Observation Testa PAs were predominantly prodelphinidins in purple-flowered seeds.
- Observation Testa PAs were predominantly procyanidins in pink-flowered seeds.
- Association Prodelphinidins had higher antioxidant activity than procyanidins.
- Association Prodelphinidins were more likely to sequester iron than procyanidins.
- Association A B testas resisted seed rot more than A b testas, but the difference was slight.
- Recommendation The authors consider growing pink-flowered pea acceptable despite its slightly lower resistance.
