T. Ishikawa,A. Hayashi,Shiro Nagamatsu,Yasushi Kyutoku,Ippeita Dan,T. Wada,Koichiro Oku,Y. Saeki,T. Uto,Takanari Tanabata,Sachiko Isobe,Nobuo Kochi +11 more
TL;DR: The results suggest machine learning's high ability to classify fruit shapes accurately and will attempt to increase the classification accuracy and apply the machine learning methods to other plant species.
Journal ArticleDOI
Strawberry fruit shape: quantification by image analysis and QTL detection by genome-wide association analysis
Shiro Nagamatsu,Masao Tsubone,Takuya Wada,Koichiro Oku,Miyuki Mori,Chiharu Hirata,Atsushi Hayashi,Takanari Tanabata,Sachiko Isobe,Kinuko Takata,Katsumi Shimomura +10 more
TL;DR: The results provide a novel and effective method to analyze strawberry fruit morphology; the detected QTLs and presented method can support marker-assisted selection in practical breeding programs to improve fruit shape.
Journal ArticleDOI
Genome-wide Association Study of Strawberry Fruit Quality-related Traits Using a MAGIC Population Derived from Crosses Involving Six Strawberry Cultivars
Journal ArticleDOI
Detection of Chromosomal Regions for Male Sterility in the Cultivated Strawberry Fragaria × ananassa Duch.
Takuya Wada,Takayuki Sueyoshi,Chiharu Hirata,Kinuko Takata,Yuji Noguchi,Sono Kataoka,Sachiko Isobe,Miyuki Mori,Shiro Nagamatsu,Yoshiki Tanaka,Katsumi Shimomura +10 more
TL;DR: Quantitative trait locus analyses for pollen fertility revealed that male sterility was controlled by three independent chromosomal regions in these populations, which corresponded to chromosome 4 in the wild strawberry (Fragaria vesca) genome.
Journal ArticleDOI
Comparative QTL mapping for male sterility of cultivated strawberry (Fragaria × ananassa Duch.) using different reference genome sequences
Takuya Wada,Hiyori Monden,Sachiko Isobe,Kenta Shirasawa,Takayuki Sueyoshi,Chiharu Hirata,Miyuki Mori,Shiro Nagamatsu,Yoshiki Tanaka +8 more
TL;DR: QTL mapping to different reference genomes clearly showed the specific features of each reference genome, and that using different kinds of reference map could accelerate fine mapping and map-based cloning of certain genes of cultivated strawberry.
