Yellow Lupin Flowering Time QTL Mapping Data from Greenhouse Trials

A recombinant inbred line population of 1,448 genotyped loci was phenotyped for flowering time across three spring seasons (2022-2024) and one winter season (2023/4). The dataset, authored by Ishani Dogra, contains quantitative trait locus mapping results for vernalization and photoperiod response in yellow lupin (Lupinus luteus L.). It identifies a major QTL on chromosome YL-16 explaining up to 34% of phenotypic variance and co-localizing with the LlutFTc1 gene.

Use Cases

• Identify candidate genes for flowering time regulation based on QTL co-localization with known homologues like LlutFTc1.
• Study genotype-by-environment interaction for flowering based on phenotyping under long-day and short-day photoperiods.
• Validate marker-trait associations using the developed marker for the 2,227 bp indel in the LlutFTc1 promoter.
• Compare the genetic architecture of vernalization response between different photoperiod conditions based on identified major and minor QTLs.

Strengths

• Genetic map anchors all 26 yellow lupin pseudochromosomes with 1,448 loci.
• Phenotypic data spans multiple years (2022-2024) and photoperiod conditions, showing differences up to ~68 days in flowering time.
• Major QTL is reported as significant across all years and both tested photoperiods.

Limitations

• The linkage map is moderately fragmented into 63 linkage groups versus 26 chromosomes.
• Row count and specific column-level documentation are unknown, requiring inspection after download.
• Data may reflect bias inherent to the specific parental lines and controlled greenhouse conditions used.
