This research combines long and short-read sequencing with a dense genetic map to create a chromosome-level genome assembly for Lima bean (*Phaseolus lunatus* L.). Annotation reveals diverse disease resistance genes. Comparative genomics with common bean shows high synteny and chromosomal rearrangements. Population genomic analysis identifies six wild Lima bean clusters and three sub-clusters within Mesoamerican landraces. RNA-seq data highlight genes involved in pod dehiscence and seed development. These resources will advance understanding of *Phaseolus* evolution and aid climate-resilient breeding.
