- Association Chromosome number was positively correlated with floral and vegetative characters including pollen size.
- Observation Chiasmata frequency was about 0.63 per chromosome in diploids.
- Observation Chiasmata frequency was about 0.62 per chromosome in tetraploids.
- Observation Multivalents were common in tetraploids.
