Yellow Lupin Flowering Time QTL Mapping Data from Greenhouse Trials

A recombinant inbred line population of 1,448 genotyping loci was phenotyped for flowering time across three spring seasons (2022-2024) and one winter season. The data, published by Ishani Dogra on figshare, identifies a major quantitative trait locus on chromosome YL-16 explaining up to 34% of phenotypic variance. Several minor QTLs were also detected, co-localizing with candidate flowering regulator genes.

Use Cases

• Validate the major QTL on chromosome YL-16 for early flowering based on the described marker developed from the LlutFTc1 promoter indel.
• Investigate photoperiod-specific genetic effects based on QTLs identified under long-day (YL-04) and short-day (YL-14) conditions.
• Perform comparative genomics on flowering time regulators using the candidate genes EAF1B-like, CIB2-like, and bHLH93-like mentioned in the dataset.
• Assess the phenotypic variance explained by different genetic loci across multiple growing seasons as described.

Strengths

• Genetic map anchors all 26 yellow lupin pseudochromosomes with 1,448 loci, providing broad genome coverage.
• Phenotyping was conducted across multiple seasons (2022-2024) and under different photoperiods, capturing environmental variation.
• A major QTL was consistently significant across all years and photoperiods, explaining up to 34% of phenotypic variance.

Limitations

• The linkage map is moderately fragmented into 63 linkage groups versus 26 chromosomes, which may complicate genetic analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
