Other claims from this paper (12)
- Observation Analyzed plants were diploid with 2n=2x=14.
- Observation Meiosis showed seven bivalents at metaphase and four microspores after division.
- Observation Pollen viability was 85.55% and 89.7%.
- Observation Some pollen mother cells contained univalents at 0.58% and 0.31%.
- Mechanism Univalents may indicate genetic isolation.
- Observation Tetravalents were present at 0.17% and 4.81%.
- Mechanism Tetravalents suggest heterozygosity for reciprocal translocation.
- Observation Abnormalities included laggards, chromatin bridges and micronuclei.
- Observation Abnormalities included unoriented bivalents, asynchronous divisions and syncytia.
- Observation Abnormalities included triads and cytomixis.
- Observation Caryopsis production ranged from 46.62 to 49.3%.
- Mechanism The cytogenetic findings alone appear insufficient to explain low caryopsis production or reliance on bulbs.
