A user-friendly, menu driven, database program was developed to facilitate storage, retrieval, and manipulation of data associated with a sweetpotato breeding program. The database is written in FoxBASE+ for IBM and compatible personal computers. The database consists of a variety of test options with statistical capabilities for analysis of raw test data for commonly evaluated factors used to screen sweetpotato selections. The database also contains options which permit the user to query the stored data. An important feature is the summarization of test data for individual selections based on all the tests it has been entered into. Overall means, SDs and comparisons with user specified checks are listed in a printout for each factor along with morphological descriptors, parentage, and a note section. The database also assists the user in field research through recording of plot plans, data collection forms and related data query options.

To be successful, a breeding program has to be able to track all its seedlings at every stage of testing and to ensure that the origin of each seedling product (e.g., fruit) tested is correctly recorded. The Washington State University apple

fruit quality is a major part of any apple breeding program, and breeders are constantly searching for methods to help measure these important traits. To date, sensory analysis is by far the most preferred form of testing for crispness; however, there is
