Other claims from this paper (19)
- Observation Twelve of fourteen allozyme loci were polymorphic.
- Observation Polymorphism differed significantly among loci.
- Observation Alleles per locus ranged from 1.56 to 3.67.
- Observation Genotypes per locus ranged from 1.61 to 7.11.
- Observation Effective alleles per locus ranged from 1.02 to 2.50.
- Observation Expected heterozygosity ranged from 0.02 to 0.56.
- Observation Allele frequencies differed at the same locus.
- Observation Genetic differences among provenance populations were large.
- Observation Germanic provenances had relatively lower mean allele number, effective allele number and heterozygosity.
- Observation Genetic differentiation in Germanic provenances was lower within groups and greater among groups.
- Observation Hungarian and Slovak provenances had greater within group genetic variation.
- Observation Hungarian and Slovak provenances had smaller among group differences.
- Observation Within group differentiation exceeded among group differentiation overall.
- Observation Seed sources lacked evident geographic structure.
- Observation European and US provenances did not differ observably.
- Observation Most loci did not deviate significantly from Hardy-Weinberg equilibrium.
- Observation Allele and genotype frequencies were relatively stable among groups.
- Observation Mean gene differentiation coefficient was 0.052.
- Recommendation The authors recommend initial breeding selections based on within population variation.
