Arabidopsis thaliana Fitness and Selection Data Across Three Years

Over 200 recombinant inbred lines derived from Italian and Swedish Arabidopsis thaliana populations were planted at a Swedish site for three consecutive years. The dataset enables analysis of among-year variation in selection on germination timing and the genetic basis of fitness across the entire life cycle. It supports QTL mapping for fitness components and the quantification of conflicting selection pressures.

Use Cases

• Map quantitative trait loci (QTL) for fitness and its components using data from over 200 recombinant inbred lines.
• Quantify selection on timing of germination during different life stages, such as seedling establishment versus adult survival and fecundity.
• Analyze among-year variation in the effects of fitness QTL across three consecutive growing seasons.
• Examine the performance difference between local Swedish and non-local Italian genotypes across multiple years.
• Investigate conflicting selection pressures on life-history traits that vary in direction and magnitude annually.

Strengths

• Data spans three consecutive years, enabling analysis of temporal variation in selection.
• Includes observations from over 200 recombinant inbred lines, providing genetic resolution.
• Covers the entire plant life cycle, from germination to fecundity.
• Derived from a cross between two locally-adapted populations (Italy and Sweden), offering a comparative genetic framework.

Limitations

• The dataset is limited to a single native site (Sweden), restricting geographic generalizability.
• Sample size specifics, such as the exact number of rows or observations per line, are not provided.
• Data collection ended in 2020, and conditions may not reflect more recent environmental changes.
