Development of breeding technologies and genetic analysis of important traits in horticultural crops

 Recent advances in DNA sequencing technologies are rapidly reducing the costs of genotyping. Consequently, many genes or loci that related to important agronomic traits have been identified, and breeding techniques based on genome information have been highly developed in many crops. In contrast, plant phenotyping method has improved only slow over the past decades. This is especially true for complex traits such as abiotic stress tolerance, yield potential and quality of products, which have particularly important for crop improvement and ultimately, commercial production. Therefore, it is important to improve experiment and measurement techniques that are relevant to phenotyping accuracy of such complex traits, and to try to clarify genetic mechanisms of those traits by using new phenotyping methods. Our research group has been carrying out (1) research to improve phenotyping techniques in horticultural crops, (2) development of breeding techniques based on genome information in horticultural crops, and (3) genetic resource researches on cucurbits and identification and development of breeding material with useful traits. Through these researches, we will not only clarify genetic mechanisms that govern important agronomic traits, but also develop useful breeding techniques and materials that lead to decision-making support of breeders, improvement of selection efficiency, and development of new cultivar in horticultural crops.
