This chapter presents an overview of the successful transfers of useful genes from wild species to related field crop plants. The chapter focuses on the problems associated with utilizing interspecific hybrids for improving crop species, methods used to overcome these obstacles, an assessment of the value of making the effort to produce something valuable, and the potential of utilizing other wild species germplasm. Attempts to utilize wild species germplasm to improve a crop species depend on species relationships, modes of reproduction, the extent to which the crop can be changed genetically without reducing the economic value, the number of genes controlling the trait in question, methods to overcome undesirable linkage groups, ease and power of screening procedures, and the amount of effort that can be devoted to the problem. The chapter also discusses biosystematics—such as taxonomy and species relationships—barriers to hybridization, and approaches used for germplasm exploitation. Germplasm resources in wild species have been most utilized when desirable genes were unavailable in the crop species. Although wild species have commonly been used as a source for disease resistance in some crops, a great void of knowledge exists for most groups.
