appears that sweet potato flour could substitute for a good pro-
portion of the wheat flour now imported in the Caribbean.

Future Prospects, Plans, and Needs
 The greatest need for the future is to get people excited about
the sweet potato. If others can share our dreams they need not
establish rival, duplicative, or competitive programs. In place of
this, all comers are welcome to try our plant materials and our
processes. Furthermore, we are convinced that our own findings
on production techniques, the techniques developed by our sister
institutions, and the advances in weevil control developed and
tested in AVRDC, Taiwan can make it possible to produce better
sweet potatoes.
 We especially need serious cooperators who will plant our
varieties side-by-side with those already available, and who will
help others to understand and to try the new sweet potatoes. This


process must be a continuous effort. We expect to be developing
and releasing new varieties continuously over a long period of
time. Some of our goals will be easily reached, including in-
creased developing tolerances to some common stresses. On the
other hand, I am not convinced that we shall succeed in obtain-
ing weevil-resistant varieties.
 In order to fulfill the potentials of the sweet potato we need
entrepreneurs as well, large and small, who will look to the sweet
potato as a source of income. This is difficult since the sweet
potato is not a glamorous food, nor is it pushed by large food
chains nor supported by a well developed marketing system. Yet,
sweet potato can fill new roles, and people now can define these
roles.
 It is only through an extension of the work already successfully
begun that sweet potato can become what its nature suggests,
"our daily bread."
