Pooled DNA sequencing in hairy vetch ( Roth) reveals QTL for seed dormancy but not pod dehiscence.

Introduction: Hairy vetch () is a promising legume cover crop, but its use is limited by high rates of pod dehiscence and seed dormancy.

Methods: We used phenotypically contrasting pooled DNA samples (n=24 with 29-74 individuals per sample) from an ongoing cover crop breeding program across four environments (site-year combinations: Maryland 2020, Maryland 2022, Wisconsin 2021, Wisconsin 2022) to find genetic associations and genomic prediction accuracies for pod dehiscence and seed dormancy. We also combined pooled DNA sample genetic association results with the results of a prior genome-wide association study.

is an incompletely domesticated annual legume of the Fabaceae family native to Europe and Western Asia. is widely used as a cover crop and forage due to its ability to withstand harsh winters. Here, we generated a reference-quality genome assembly (Vvill1.

Genome-wide association mapping in hairy vetch () discovers a large effect locus controlling seed dormancy.

Hairy vetch ( Roth), a winter-hardy annual legume, is a promising cover crop. To fully leverage its potential, seed production and field performance of must be improved to facilitate producer adoption. Two classic domestication traits, seed dormancy (hard seed) and dehiscence (pod shatter), are selection targets in an ongoing breeding program.
