<\/a>For breeding of super rice varieties with useful new genes, it is important to promote allelic exchange in existing cultivars by crossing them with wild or genetically remote cultivars. However, hybrids are rarely obtained from such distant crosses due to multitude of reproductive barriers. Interestingly, we found a fertile tetraploid progeny derived from anther culture of Asian rice cultivar, O. sativa, and African rice cultivar, O. glaberrima. Using genomic and phenotypic analyses, we now aim to clarify mechanisms involved in recovery of seed set in these plants. Furthermore, we hope to establish a novel remote cross breeding strategy in rice that overcomes reproductive barriers by introduction of polyploidization and haploidization.<\/p>\n![\"\"](\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas01_pstress\/img_NAGAKI.png\")

<\/a>Computers have revolutionized plant breeding, leading to the advent of ‘genomic breeding,’ which utilizes genome-wide information to model and predict phenotypic variation. Furthermore, recent advancements in DNA sequencing technology have generated vast amounts of genome and transcriptome data. However, the application of this data to practical breeding has been limited. Our research group aims to develop efficient methods to integrate various omics data for the exploration of agriculturally valuable genes and the production of new breeding materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
