A genome-wide association study was performed on a complex mapping population for 39 traits: 9 seedling-establishment traits, 14 root and nutrient-uptake traits, 5 plant morphological traits, 4 lodging resistance traits, and 7 yield and yield-contributing traits. A total of 10 significant marker-trait associations (MTAs) were found along with 25 QTLs associated with 25 traits. The percent phenotypic variance explained by SNPs ranged from 8% to 84%. Grain yield was found to be significantly and positively correlated with seedling-establishment traits, root morphological traits, nutrient uptake-related traits, and grain yield-contributing traits. The genomic colocation of different root morphological traits, nutrient uptake-related traits, and grain-yield-contributing traits further supports the role of root morphological traits in improving nutrient uptake and grain yield under DDSR. The QTLs/candidate genes underlying the significant MTAs were identified. The identified promising progenies carrying these QTLs may serve as potential donors to be exploited in genomics-assisted breeding programs for improving grain yield and adaptability under DDSR.","2019-06","published",,"Scientific Reports (TSI)","9 (1)","9334","Springer Nature Publishing",,"1-16",,,,,,"10.1038/s41598-019-45770-3",,,,,"TRUE",,"2045-2322",,,,,,"","https://doi.org/10.1038/s41598-019-45770-3","https://scholar.google.co.in/scholar?hl=en&as_sdt=0%2C5&q=Deciphering+the+genetic+basis+of+root+morphology%2C+nutrient+uptake%2C+yield%2C+and+yield-related+traits+in+rice+under+dry+direct-seeded+cultivation+systems&btnG=","pub",,"Asian Development Bank","TA8441-Development and dissemination of climate-resilient rice varieties for water-short areas of South Asia and Southeast Asia",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
