| Abstract: | Numerous genes of great value urgently needed by the crops exist in wild species. Identification and utilization of these genes through interspecific hybridization has been the most important approach for crop improvement. In this paper, the author gave a brief review on the history of the first successful interspecific hybridization between cucumber and C. hys- trix, introduced the recent progress made in germplasm development, mainly addressed the methogology in identifying and utilizing the wild genes through interspecific introgression, and finally proposed the great potential for cucumber genomics and cultivar improvement from this unique interspecific hybridization. The information in this paper is very useful to cucurbit genetic research and breeding practice. |
