Indian rice lines stacking four drought genes yield up to 82% more under water stress
Breeding lines that pyramid the qDTY2.1, qDTY3.1, qDTY1.1 and qDTY2.2 drought-tolerance QTLs into DRR Dhan 50 out-yielded the parent by 36 to 82% under drought in a study by Malla Reddy University, ICAR-IIRR and partners, using marker-assisted conventional crossing rather than gene editing.
