Other claims from this paper (6)
- Association Cyanogenesis, V leaf mark and leaf size declined with increasing latitude and altitude of origin.
- Association Early flowering, flower abundance and spring growth declined with increasing latitude and altitude of origin.
- Observation Geographic groups of white clover were phenotypically heterogeneous, with populations from the same region in several clusters.
- Observation Road-side collections occurred in several clusters and did not form an identifiable phenotypic group.
- Observation The southern Europe collection contained a group of very small-leaved, prostrate, non-productive populations not found in any cultivar grouping.
- Recommendation Clustering analyses assist the use of new germplasm by identifying similar accessions and reducing the number of lines to be evaluated.
