Table 1 Means for days to flowering (DTF), plant height (PHT), and grain yield (GY) of MRQ74 PLs as compared to MRQ74 under lowland reproductive stage drought stress and non-stress conditions

From: Pyramiding of drought yield QTLs into a high quality Malaysian rice cultivar MRQ74 improves yield under reproductive stage drought
