Other claims from this paper (8)
- Observation Broad-sense heritability of angular leaf spot resistance in the strawberry panel was moderate.
- Observation Narrow-sense heritability of angular leaf spot resistance was low.
- Mechanism The low narrow-sense heritability reflects non-additive genetic effects such as dominance and epistasis.
- Observation A GWAS locus on chromosome 1D explained 5% of phenotypic variance in angular leaf spot resistance.
- Observation A GWAS locus on chromosome 2D explained 18% of phenotypic variance in angular leaf spot resistance.
- Observation A significant epistatic interaction between a locus on chromosome 2D and an additional locus on chromosome 6B explained 15% of phenotypic variance.
- Mechanism Non-additive effects in these strawberry populations control angular leaf spot resistance.
- Recommendation The findings underscore the need for predictive breeding strategies that capture epistatic and environmental variance in strawberry.
