However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties combining improved drought resistance with high yield under favorable conditions and quality characteristics preferred by farmers are the most promising and deliverable technologies for alleviating povertyRiceGeneticsRiceGenetic engineeringRiceBreedingGrainDrought toleranceRiceGenetics.RiceGenetic engineering.RiceBreeding.GrainDrought tolerance.633.1/8633.18Serraj Rachid980305Bennett J1134195Hardy Bill1593044International Rice Research Institute.MiAaPQMiAaPQMiAaPQBOOK9910825594003321Drought frontiers in rice4060667UNINA
