Other claims from this paper (5)
- Observation Plant height and soluble starch content were the most robust indicators of triploid heterosis in loquat among eight vigor-related traits.
- Observation Paternal-excess triploids [3x(p)] consistently outperformed all other groups.
- Association Parent-of-origin effect was the main positive driver of triploid heterosis, +10.37% for plant height.
- Association Ploidy level had a negative impact on triploid heterosis (-20.87%), smaller in magnitude than the parent-of-origin effect.
- Recommendation The authors propose a breeding strategy that prioritizes paternal-excess crosses combined with novel InDel markers for rapid verification of superior seedless progeny.
