Outline of Final Research Achievements

In order to genome-based breeding techniques for cucumber and melon, this study performed clarify the inheritance of important fruit quality traits based on genetic analyses with new phenotyping method based on information processing techniques. Specifically, we focused on cucumber and melon genetic resources that exhibited wide variation in fruit morphological traits, such as fruit size, shape and fruit texture traits, evaluated their phenotypes quantitatively, and detected quantitative trait locus associated with these traits by QTL analyses. Based on these results, marker assisted selection systems can be developed for fruit quality traits in cucumber and melon.
