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

Ishani Dogra's dataset contains quantitative trait locus (QTL) mapping results for vernalization-insensitive and photoperiod-independent early flowering in yellow lupin (Lupinus luteus L.). The data is derived from a recombinant inbred line population phenotyped in greenhouse trials across three spring seasons (2022-2024) and one winter season (2023/4), with genotyping performed using DArT-seq. The dataset was last updated on 2026-04-23 and is shared under a CC-BY-4.0 license.

Use Cases

• Identify major genetic loci controlling flowering time based on the QTL located on chromosome YL-16.
• Study genotype-phenotype correlations using the marker developed for the LlutFTc1 gene promoter indel.
• Analyze the effect of photoperiod on flowering time using data from long-day and short-day experimental conditions.
• Investigate minor genetic regulators of flowering based on QTLs identified on chromosomes YL-04 and YL-14.

Strengths

• Includes phenotypic data from controlled greenhouse trials across multiple seasons (2022-2024).
• Genetic analysis is based on a linkage map comprising 1,448 loci anchoring all yellow lupin pseudochromosomes.
• Identifies a major QTL explaining up to 34% of phenotypic variance for flowering time.

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).
