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 was generated from a recombinant inbred line population phenotyped in greenhouse conditions across three spring seasons (2022-2024) and one winter season (2023/4), with genotyping performed via DArT-seq. The dataset was last updated on 2026-04-23.

Use Cases

• Identify candidate genes for flowering time regulation based on the co-localization of a major QTL with the LlutFTc1 gene.
• Analyze the effect of photoperiod on flowering time using phenotypic variance explained by QTLs specific to long-day and short-day conditions.
• Study genetic map construction and collinearity in yellow lupin using the linkage map comprising 1,448 loci.
• Validate markers for plant phenology, such as the 2,227 bp indel marker from the LlutFTc1 promoter, for breeding applications.

Strengths

• Includes a linkage map with 1,448 loci anchoring all yellow lupin pseudochromosomes.
• Phenotypic data spans multiple seasons (2022-2024) and photoperiods (long-day and short-day).
• Identified a major QTL explaining up to 34% of phenotypic variance and several minor QTLs with specific environmental effects.

Limitations

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