IRRI - Int. Rice Research Institute• Founded in 1960 by Rockefeller and Ford Foundations• Flagship center of CGIAR• Green Revolution in Asia initiated through the release of

IR8 with sd1 for semi-dwarf stature

Mission• To reduce poverty and hunger, improve the health of rice

farmers and consumers, and ensure environmental sustainability through collaborative research, partnerships, and the strengthening of national agricultural research and extension systems.

• Scored traits:leaf rolling, leaf drying, relative water content, leaf conductivity, SPAD reading,

flowering date, maturity date, recovery, plant height, biomass, grain yield, etc.

• Green house test• 144 varieties selected from the first field test were re-screened in green house with 5 replicates, 5 plants per row.

• Field test•300 varieties have been screened in field with 3 replicates, 5 plants per row.•another set of 300 lines is being tested.

Association of ERF4 haplotypes with Yield

Yield decline in the 2004 and 2005 dry season. Letters a, b indicate significant differences between haplotypes within the indica group; Letters d, e indicate significant differences between haplotypes within the japonica group; The letter case differentiates the data obtained from different seasons; bars without letters are not significantly different from the others within the specific subgroup at P=0.05.

Summary

• Defined population structure for representative collection

• Identified candidate genes• Implemented targeted SNP detection by

EcoTILLING• Increased throughput by optimizing agarose-based

detection• Replicated phenotyping undertaken for vegetative

stage drought• Applying association tests for drought traits to

verified haplotypes
