- Observation Groups from continuous and discrete traits did not agree under Tocher optimization.
- Method / resource Discrete variables separated Vitis vinifera and hybrids into different groups.
- Association Bunch weight, length and width had significant positive correlations.
- Association Titratable acidity and TSS/TTA were negatively correlated.
- Method / resource Four principal components explained 84.12% of total variation.
- Observation Wine grape accessions showed little variability in the collection.
