Other claims from this paper (15)

Observation Across both marker systems, 160 loci were scored.
Observation Across both marker systems, 138 loci were polymorphic.
Observation SCoT generated 79 loci.
Observation SCoT produced 64 polymorphic loci.
Observation SRAP generated 81 loci.
Observation SRAP produced 77 polymorphic loci.
Observation SCoT polymorphism per primer ranged from 75% to 100%.
Observation SCoT PIC values were between 0.12 and 0.26.
Observation SRAP polymorphism per combination ranged from 85.7% to 100%.
Observation SRAP PIC values were between 0.22 and 0.33.
Observation UPGMA clustering of the combined matrix separated cultivated controls from wild accessions.
Observation PCA supported the same genetic structure as the clustering.
Method / resource The high cophenetic correlation confirmed strong agreement between the dendrogram and the original dissimilarity matrix.
Method / resource Amplification profiles were clear and reproducible.
Method / resource The combined SCoT and SRAP approach provided a robust and practical framework for germplasm structuring and parent selection.

Other claims from this paper (12)

Observation Meiosis showed seven bivalents at metaphase and four microspores after division.
Observation Pollen viability was 85.55% and 89.7%.
Observation Some pollen mother cells contained univalents at 0.58% and 0.31%.
Mechanism Univalents may indicate genetic isolation.
Observation Tetravalents were present at 0.17% and 4.81%.
Mechanism Tetravalents suggest heterozygosity for reciprocal translocation.
Observation Meiotic abnormalities had cumulative frequencies of 5.71 to 6.63%.
Observation Abnormalities included laggards, chromatin bridges and micronuclei.
Observation Abnormalities included unoriented bivalents, asynchronous divisions and syncytia.
Observation Abnormalities included triads and cytomixis.
Observation Caryopsis production ranged from 46.62 to 49.3%.
Mechanism The cytogenetic findings alone appear insufficient to explain low caryopsis production or reliance on bulbs.
