Rice has an unusual depth of genetic and phenotypic variation due to years of domestication and selection under very diverse environments.  Its history as a crop provides us with the capacity to conduct comprehensive phenotypes under multiple conditions. We will conduct phenotyping on the SNP-set to enable correlation of allow allelic differences across diverse rice varieties. Under the collaborative network, two main activities will be pursued:
  1. Evaluations of multiple phenotypes, including
    •     Morphological characters at vegetative and reproductive stages
    •     Biomass accumulation and yield performance under multiple locations
    •     Response to major environmental stresses (diseases, water, salinity, soil toxicity,etc.)
    •     Grain properties and nutrient contents
  2. Develop genetic stocks that allow segregation analysis of genetic and phenotypic variation.

IRRI is in the process of developing recombinant inbred lines (RILs) from selected SNP lines that capture the genetic and phenotypic.  Pairwise crosses are being made and these will be advanced to F2.  We expect research groups within the consortium will select certain crosses to advanced to RILs (F6) for trait dissection.
