Genomic Dissection of germination from deep sowing depth under direct seeded cultivation conditions using ddRAD Sequencing

Improving seedling vigour remains a key objective for breeders working with direct seeded rice (DSR) cultivation conditions. The present study aims to understand the genetic control of seedling vigour in deep sown DSR. Combined genome-wide association mapping, linkage mapping, and fine mapping were performed to identify the genomic regions associated with germination from deep sowing depth under direct seeded cultivation conditions. The 881 kb region on chromosome 7 is reported to be associated with mesocotyl elongation
