Yellow Lupin Flowering Time QTL Mapping Data from Greenhouse Trials

A recombinant inbred line population from a cross between yellow lupin cultivars PRH444/14 and Parys was phenotyped for flowering time across three spring seasons (2022-2024) and one winter season (2023/4). The dataset includes genotyping data from DArT-seq and results from composite interval mapping that identified a major quantitative trait locus on chromosome YL-16 explaining up to 34% of phenotypic variance. The data was authored by Ishani Dogra and shared under a CC-BY-4.0 license.

Use Cases

• Validate the major QTL on chromosome YL-16 for vernalization-insensitive early flowering based on the described marker-trait correlation.
• Investigate the effects of photoperiod on flowering time genetics using the long-day and short-day phenotyping data mentioned.
• Perform candidate gene analysis for the minor QTLs on chromosomes YL-04 and YL-14 based on the described EAF1B-like, CIB2-like, and bHLH93-like genes.
• Assess linkage map collinearity and fragmentation (63 linkage groups vs. 26 chromosomes) for genomic studies in yellow lupin.

Strengths

• Phenotyping spans multiple seasons (2022-2024) and photoperiod conditions (long-day and short-day).
• Genetic map comprises 1,448 loci anchoring all yellow lupin pseudochromosomes.
• A major QTL explains a defined portion of phenotypic variance (up to 34%).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The linkage map is described as moderately fragmented (63 linkage groups versus 26 chromosomes).
