Conilon Coffee Genotypes and Their Reaction to Rust Under Controlled Conditions

54 conilon coffee clones were evaluated for resistance to coffee leaf rust under controlled temperature and photoperiod. The study used a randomized design with three replicates, measuring incubation period, latent period, incidence, sporulation, spores, and severity. Rodolfo Ferreira de Mendonça authored this research, which identified 19 resistant, 19 moderately resistant, and 16 susceptible genotypes.

Use Cases

• Classifying coffee genotypes into resistance categories based on measured phenotypic components.
• Identifying candidate clones for breeding programs based on resistance to H. vastatrix.
• Analyzing relationships between different resistance components like incubation period and severity.
• Comparing the performance of different genotypes under standardized controlled conditions.

Strengths

• The dataset includes results for 54 distinct coffee genotypes.
• Experimental design was standardized with three replicates and controlled environmental conditions.
• Six specific resistance components were evaluated, providing a multi-faceted view of rust reaction.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect experimental bias inherent to controlled laboratory conditions.
