- T his document has been prepared with support of the University of California Genetic Resources Conservation Program (UC GRCP) as part of its continuing effort to assess the value, status, and needs for access and conservation of crop genetic resources important for California. The California walnut industry has been remarkably successful, accounting for 99% of the US walnut production with a $267 million contribution to the state's economy (California Dept. of Food and Agriculture 1993). Components of this success, of course, include cultivars accepted by the producers and consumers, skillful horticultural practices, astute marketing, fortuitous climate, and available water. These were detailed and discussed in a report recently produced by a Walnut Industry Study Group convened by the University of California Agricultural Issues Center (Coppock 1994). This document emphasizes the genetic contributions to the success of walnuts in California. Genetic diversity is key to the sustained productivity of crops. Without it, there can be no new cultivars to meet society's future needs, which are unpredictable.

- T his publicationis dedicated to Eugene F. Sen and Harold I. Forde who conducted the walnut breeding program at the University of California, Davis from 1948 to 1978. Serr andForde's collaboration was collegal and productive. This brief history of some of their work and the description of their walnut germplasm collection is a tribute to them and to their success.
