Other claims from this paper (9)
- Method / resource The model failed to fit total pectin, fracture hardness, and cohesiveness in Scarlet Warren × CF2.
- Method / resource The model fit all Scarlet Warren × CF4 attributes except dry matter and springiness.
- Observation Additive gene effects were negative for dry matter, alcohol-insoluble solids, sucrose, soluble pectin, and adhesiveness.
- Observation Additive gene effects were positive for glucose, fructose, total pectin, and springiness.
- Observation Dominance gene effects were negative for alcohol-insoluble solids and total pectin.
- Observation Dominance gene effects were positive for three sugars, soluble pectin, springiness, and adhesiveness.
- Observation Most attributes except sucrose had low heritability, suggesting larger environmental than genetic effects.
- Recommendation The authors concluded that breeding sweeter squash is feasible.
- Recommendation The authors concluded that breeding for texture improvement is problematic due to environmental effects.
