Sammendrag
Red clover (Trifolium pratense L.) is a globally significant forage legume in pastoral livestock
farming systems. It is an attractive component of grassland farming, because of its high yield and
protein content, nutritional value and ability to fix atmospheric nitrogen. Enhancing its role further
in sustainable agriculture requires genetic improvement of persistency, disease resistance, and
tolerance to grazing. To help address these challenges, we have assembled a chromosome-scale
reference genome for red clover. We observed large blocks of conserved synteny with Medicago
truncatula and estimated that the two species diverged ~23 million years ago. Among the 40,868
annotated genes, we identified gene clusters involved in biochemical pathways of importance for
forage quality and livestock nutrition. Genotyping by sequencing of a synthetic population of 86
genotypes show that the number of markers required for genomics-based breeding approaches is
tractable, making red clover a suitable candidate for association studies and genomic selection.
