  1. 1. Breeding for Improving DroughtTolerance in Rice Mega Varieties: Progress at IRRI Integrated plant breeding Platform annual meeting June 1-3, 2011, Wageningen Netherlands B.P. Mallikarjuna Swamy
  2. 2. “I challenge the next generation to usenew scientific tools and techniques toaddress the problems that plague the world’s poor.” Dr. Norman Borlaug hastens the process of development of Commercial Products

  4. 4. Major goalDevelopment of drought tolerant rice varieties with anyield advantage of 1.0 to 1.2 tha over the control• High yield under normal situation• Tolerant to blast, brown spot, bacterial leaf blight• Good grain quality/quality maintenance under drought• High framers’ preference
  5. 5. Drought Research at IRRI: StrategyConventional approaches• Use improved pre-breeding lines as donors• Direct selection for grain yield• Combine high yield potential with good yield under drought• Confirm performance in multi location testing in target environment-Drought breeding networkMolecular approaches• Use traditional/wild donors in mapping populations• Identify major drought yield QTLs• Introgress QTLs in improved drought susceptible varieties by MAB• Physiological and molecular mechanism of QTLs drought tolerance
  6. 6. Some initial success• During 2009-11, 6 varieties: Sahbhagi dhan-IR74371-70-1-1 in India, Tarharra 1 -IR 80411-B-49-1, Sukha dhan 1- IR74371-46-1-1, Sukha dhan 2- IR74371-54-1-1, Sukha dhan 3- IR74371-70-1-1 in Nepal and Sahod Ulan 1 - IR74371-54-1-1 in Philippines released.• Release of IR74371-70-1-1 in Bangladesh under process.• These provide 0.8-1.2 t ha -1 yield advantage under moderate to severe Sahbhagi dhan in India drought while maintaining high yield under normal rainfall situation. Tarharra 1 in Nepal Sahod Ulan 1 in Philippines
