Other claims from this paper (8)
- Observation Half-sib families varied phenotypically and genetically in shoot and root traits.
- Observation Shoot height and root collar diameter had high heritability, up to 0.90.
- Observation Other shoot and root traits had low to moderate heritability.
- Association Shoot traits and shoot-root traits showed high phenotypic correlations of 0.82–0.91.
- Association Shoot traits and shoot-root traits showed high genetic correlations of 0.70–0.90.
- Association Root length was poorly correlated with other traits.
- Association Genetic variance explained a large proportion of variance in shoot and root traits.
- Recommendation The authors recommend shoot height or root collar diameter for selection for seedling growth and survival.
