Scientists statewide are testing varieties of large-seeded and baby limas, both bush and vine types, for qualities that are great for consumers and for growers facing a range of conditions. Research updates were presented at the 2025 UC Dry Bean Field Day.
UC Davis researchers are developing improved lima bean varieties suited for U.S. climates. By studying wild genetics and breeding for heat tolerance, yield, and nutrition, they aim to expand lima bean cultivation and consumer appeal nationwide.
UC Davis researchers are leading a $3.3 million project to improve lima bean breeding. The initiative focuses on traits like heat tolerance and disease resistance and aims to develop climate-resilient varieties and create a public genetic database for breeders.
