Other claims from this paper (9)
- Observation Twelve of fifteen lines had chromosome numbers from 2n=53 to 58.
- Observation One line had 50 to 52 chromosomes.
- Observation Two lines had 42 chromosomes.
- Observation Meiosis was more regular in 42-chromosome plants than in 54-, 56- or 58-chromosome plants.
- Observation Amphiploid progeny tended to stabilize at octoploid or hexaploid level.
- Observation Different octoploid lines differed in several chromosomes.
- Observation Octoploids appear to possess all three natural hexaploid genomes, with some structural modifications.
- Observation One derived hexaploid line resembled the parental hexaploid phenotype.
- Observation Another derived hexaploid line combined traits of both parents.
