Other claims from this paper (14)
- Observation Flowering aneuploids had reduced corolla size.
- Observation Flowering aneuploids had altered pigmentation.
- Observation Flowering aneuploids showed partial conversion of stamens into petaloid organs.
- Observation The flowering lines were aneuploid with 150–182 chromosomes.
- Observation Pollen morphology was variable, with malformations and broad size distributions.
- Observation Aneuploid pollen viability was markedly reduced relative to control.
- Observation Aneuploid pollen germination was markedly reduced relative to control.
- Observation Microsporogenesis produced abnormal polyads and unequal tetrads.
- Observation DFR expression was uniformly downregulated in the aneuploid lines.
- Observation F3′5′H expression responses varied among aneuploid lines.
- Observation Severe lines failed to reach full anthesis.
- Observation Severe lines showed complete male sterility.
- Association Pigmentation, floral organ composition, and male fertility traits co-varied with severity within analysed lines.
- Recommendation The authors support early ploidy screening and targeted cytogenetic triage for ornamental breeding selection.
