Development of Mapping Populations from Sheath Blight Resistant Oryza
species
Objective:
To identify sheath blight resistance rice wild relatives (Oryza
species) and incorporate this sheath blight resistance into the background of U.S. rice varieties.

Exploring the Genetic Basis of
Transgressive
Variation in Rice
Objective:
Determine if rice
sub-population structure is predictive of transgressive variation (the occurrence of progeny displaying phenotypes more extreme than either parent) and to begin to characterize the underlying genetic basis of this phenomenon.

Development of Mapping Populations between U.S. Rice
Varieties and Wild Oryza
species
Objective:
Incorporate useful traits, like sheath blight resistance, into the background of U.S. rice
varieties by developing mapping populations between the selected U.S. rice
varieties and wild Oryza
species accessions containing the desired traits.
