Yellow Lupin Flowering Time QTL Mapping Data from Greenhouse Trials (2022-2024)

A recombinant inbred line (RIL) population of 1,448 loci was developed from a cross between yellow lupin lines PRH444/14 and Parys. The population was phenotyped for flowering time across three spring seasons (2022-2024) under long-day and short-day photoperiods, with differences between early and late lines reaching ~68 days. The dataset, authored by Ishani Dogra, contains quantitative trait locus (QTL) mapping results identifying a major QTL explaining up to 34% of phenotypic variance.

Use Cases

• Validate the major QTL on chromosome YL-16 associated with the LlutFTc1 gene based on the described marker correlation.
• Investigate minor QTLs on chromosomes YL-04 and YL-14 for photoperiod-specific flowering effects mentioned in the description.
• Study genotype-phenotype relationships for flowering time under different photoperiod conditions (long-day and short-day).
• Perform comparative genetic analysis using the linkage map comprising 1,448 loci that anchors all yellow lupin pseudochromosomes.

Strengths

• The linkage map is based on 1,448 genotyped loci, anchoring all 26 yellow lupin pseudochromosomes.
• Phenotyping was conducted over multiple seasons (2022-2024) and under controlled photoperiod conditions.
• A major QTL explaining up to 34% of phenotypic variance was identified and co-localized with a candidate gene (LlutFTc1).

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, with 63 linkage groups versus 26 chromosomes.
