IX. Other Business

Dear Watermelon Research & Development Working Group Members:

As a part of the continuing effort to ensure the availability of all accessions in the Citrullus germplasm collection, volunteers are being sought to grow out one or more selected genotypes of Citrullus lanatus (var. lanatus or citroides) in isolation or in a greenhouse environment for the production of pure seed for return to the germplasm repository where it will be maintained and distributed. Anyone willing to assist in this endeavor should contact Bob Jarret at bjarret@ars-grin.gov (Tel: 770-228-7303).
