Genetic Dissimilarity for Cassava Green Mite Resistance Among Manihot Species

Nine wild Manihot accessions and two domesticated clones were evaluated for resistance to the cassava green mite (Mononychellus tanajoa) under controlled laboratory conditions. The larval-adult mite period ranged from 5.53 to 7.01 days across the genotypes, with the longest period observed on an M. glaziovii accession. V. de J. Boaventura authored this study, which used analysis of variance, cluster analysis, and principal component analysis to assess genetic variability.

Use Cases

• Identify mite-resistant cassava genotypes based on observed larval-adult development periods.
• Perform genetic dissimilarity analysis among Manihot species using the described UPGMA clustering method.
• Study the relationship between mite life cycle duration and viability on different plant hosts.
• Apply principal component analysis to explain genetic variation in pest resistance traits.

Strengths

• Specific mite life cycle durations are reported, ranging from 5.53 to 7.01 days.
• The first two principal components explained 77.50% of the total accumulated genetic variation.
• Data was collected under controlled laboratory conditions (25 ± 1°C, 70 ± 10% RH, 12-h photophase).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The dataset's scale and specific file formats are not described.
