Emmalea Ernest, extension agent in the University of Delaware’s Department of Plant and Soil Sciences (PLSC), has received federal funding from the U.S. Department of Agriculture’s Specialty Crop Block Grant (SCBG) Program for a project aimed at developing heat-tolerant lima bean varieties.
“Lima beans are Delaware’s largest acreage vegetable crop and anchor the state’s processing vegetable industry,” said Ernest. “The varieties that are currently available to growers suffer yield loss or delayed yield when they are exposed to high temperatures during flowering.”
In order to be eligible for funding from the program, grant money had to be used toward specialty crops as opposed to field crops, such as corn and soybeans, or animal agriculture. Specialty crops are a wide-ranging category that includes fruits, vegetables, dried fruits, tree nuts, horticulture, and nursery crops.
With her funding, Ernest aims to develop procedures for heat tolerance screening in the existing lima bean breeding program, examine the physiological mechanisms for heat stress tolerance or susceptibility in lima beans, and investigate the underlying genetic basis for heat stress tolerance in lima beans. Her findings could greatly impact Delaware vegetable farmers’ yields.
Ernest said she has collaborated on multiple USDA Specialty Crop Block Grants in the past six years and acknowledged that the program has been a vital source of funding to the Extension Vegetable and Fruit Research Program. The money has allowed Ernest to help address production problems many Delaware fruit and vegetable growers have experienced, as well as explore new crop prospects.
The SCBG program seeks out projects like Ernest’s in order to promote and enhance the local agricultural economy.
“My past and current grant projects through this program have included work on lima beans but also on a variety of other crops, including processing sweet corn, blueberries, snap beans, cucumbers and cantaloupes,” said Ernest.
Her research with lima beans will be over the course of the next three years and take place on UD’s research farm in Georgetown.
Ernest said that in the genetics portion of the project, which will be built off of work funded by the Building a Better Bean SCRI Grant awarded to UD researchers last year, she will be working closely with colleague Randy Wisser, assistant professor of plant and soil sciences, and Gordon Johnson, extension vegetable and fruit specialist.
