Gene-Stacked Rice: Boosting Yields in Drought Conditions
• Indian researchers have developed rice varieties with up to 82% higher yields under drought conditions using advanced breeding techniques.
• This innovation offers hope for farmers in water-stressed regions.
How QTL Pyramiding Works
QTL pyramiding involves combining multiple genetic regions linked to desired traits into a single plant through marker-assisted crossing. This method was used to integrate four drought-tolerance QTLs into the genetic background of DRR Dhan 50, a popular Indian rice variety, resulting in significant yield gains without requiring genetic modification.
