- Observation Anthracnose disease resistance had low heritability of 0.42.
- Observation White leaf spot resistance had low heritability of 0.34.
- Observation Brown leaf spot resistance had low heritability of 0.29.
- Observation Blight leaf spot resistance had moderate heritability of 0.51.
- Observation Disease resistance varied over a narrow range.
- Observation Yield traits varied over a wider range than disease resistance.
- Association Higher first discriminant-function scores were associated with increased yield traits.
- Association Higher second discriminant-function scores were associated with increased disease severity.
- Observation Most clusters had hybrid characteristics for yield traits and disease severity.
- Association Brown and blight leaf spot resistance were strongly correlated, with r = 0.96.
- Association Anthracnose resistance correlated with other diseases at r = 0.53 to 0.58.
- Association Yield traits were not significantly correlated with disease resistance.
- Observation Selection differentials for disease resistance were modest, from -2.31% to -3.61%.
- Observation Selection on fresh root yield gave an 82% differential.
- Observation Selection on dry root yield gave a 39% differential.
- Observation Selection on shoot yield gave a 49% differential.
- Observation Selection on plant vigor gave a 26% differential.
