Katy Putative Mutant population (20,103 lines)	Putative mutant set of the cv. Katy, a japonica rice well adapted for production in the southern U.S.  Katy (PI 527707) has resistance to sheath blight disease (Rhizoctonia solani) and possesses the major blast resistance genes Pi-ta, Pi-ta2, and Pi-ks.  The first subset of 15,192 putative mutants were treated by fast neutrons with 7.7 Gy, 26.3 Gy, and 49.4 Gy.  A total of 15,192 M1 panicles were harvested from 15,192 M0 and were subsequently amplified to M4 by single seed breeding method in Stuttgart, AR, from 2003 to 2006.  An evaluation of 192 randomly selected plants from the entire population in 2006 verified that they were derived from Katy based on 10 diagnostics simple sequence repeat markers.  See the evaluation results - in html and as an Excel table.  This population has been used to identify blast susceptible mutants that can be used to study molecular mechanisms of disease resistance (Jia and Martin, 2008).  This population will be useful for the identification of rice mutants that correlate with any gene in the rice genome.  Click here to view the first GRIN record in the FN set. The second subset of mutants were treated with 0.4%, 0.8%, and 1.2% ethyl methane sulfonate.  A total 4880 panicles were harvested from 4896 M0 and were subsequently amplified to M4 by single seed breeding method in Stuttgart, AR from 2004 to 2007.  This population has been used to identify lesion mimic mutants (Jia 2002) and will be useful for the identification of useful mutants for crop improvement and functional genomics.  Click here to view the first GRIN record in the EMS set.
	COLLECTIONS
CA mutants	GSOR 61 was selected in 1972 by Tseng, Carnahan, and Johnson at Biggs, California, as having resistance to cold-induced sterility.  The remainder of the CA mutants set was selected by J. Neil Rutger during his California tenure.  There are short stature and early maturing mutants developed by induced mutation.  GRIN pages:  Click here to view entries GSOR 61 through 77.
Core Collection	With 1794 entries, the Core Collection containing about 10% of the Whole Collection was assembled by stratified random sampling method in 2002, evaluated comprehensively for 25 characteristics and proven to be highly representative of the Whole Collection.  Information drawn from the Core Collection can effectively be used to assess the Whole Collection with 88% certainty.  A single plant was selected from each Core accession in 2006 and bulk seed from the selection produced in 2007 is deposited in the GSOR.  DNA extracted from the selected plant has been analyzed with 80 SSR (Single Sequence Repeat) markers that cover the entire rice genome about 30 cM apart.  A Mini-Core Collection containing about 10% of the Core Collection will be developed and fingerprinted with some 200 SSR markers.  Click here to view GRIN pages:  GSOR 310001 through 311795.  Click here to view a list of the Core Collection, available in html and Excel formats.
Jodon mutants	As Nelson E. Jodon described in the 1977 Crop Science article, this set contains "Twenty-four morphologic characters that may serve as gene markers for all except Group X of the 12 linkage groups of cultivated rice Oryza sativa L. ..."  GRIN pages:  Click here to view entries GSOR 30-60; GSOR 78-79.
