Asparagus bean (Vigna. unguiculata ssp. sesquipedialis), known for its very long and tender green pods, is an important vegetable crop broadly grown in the developing Asian countries. In this study, we reported a 632.8 Mb assembly (549.81 Mb non-N size) of asparagus bean based on the whole genome shotgun sequencing strategy. We also generated a linkage map for asparagus bean, which helped anchor 94.42% of the scaffolds into 11 pseudo-chromosomes. A total of 42,609 protein-coding genes and 3,579 non-protein-coding genes were predicted from the assembly. Taken together, these genomic resources of asparagus bean will help develop a pan-genome of V. unguiculata and facilitate the investigation of economically valuable traits in this species, so that the cultivation of this plant would help combat the protein and energy malnutrition in the developing world.
