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

Ishani Dogra published a dataset containing quantitative trait locus (QTL) mapping results for vernalization-insensitive and photoperiod-independent early flowering in yellow lupin (Lupinus luteus L.). The data was generated from a recombinant inbred line population phenotyped in greenhouse trials across three spring seasons (2022-2024) and one winter season (2023/4). It includes a linkage map with 1,448 loci and identifies a major QTL on chromosome YL-16 explaining up to 34% of phenotypic variance.

Use Cases

• Identifying candidate genes for flowering time regulation based on the co-localized LlutFTc1 gene and other regulators mentioned.
• Comparing the effect of photoperiod on flowering time QTLs based on long-day and short-day trial results.
• Assessing the genetic architecture of vernalization responsiveness in a potential alternative crop for European sandy soils.

Strengths

• Linkage map comprises 1,448 loci anchoring all yellow lupin pseudochromosomes.
• Phenotyping was conducted across multiple seasons (2022-2024) and under different photoperiods.
• A major QTL explaining up to 34% of phenotypic variance was identified and validated across years.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The linkage map is moderately fragmented, with 63 linkage groups versus 26 chromosomes.
