During his long and productive career at the LSU Rice Research Station, Dr. Nelson E. Jodon has generated a number of multiple marker stocks. These tester lines include at least one marker for 11 of the 12 linkage groups of rice (Table 1).

A number of stocks carrying unmapped genes have also been identified. These include: Pj, purple color or junctura in the absence of Pn; Plm, purple leaf margin; gf, fold furrows on hull; cr, crumbly endosperm; Gm (Jodon 1965), extremely long glumes; Sth, panicle enclosed by flag leaf sheath at maturity; Lh, long plant hairs; Pf, purple furrows on hull; Rk, dominant round kernels; mpi, mimics Piricularia susceptibility; Prb, brown pericarp non-allelic to Rc. The allelic relations between these genes and genes with similar effects from other sources are not known. It is hoped that these stocks may be useful to other researchers in assigining genes to linkage groups and in other genetic studies. Seed samples of these marker stocks and unmapped genes are available from the author. Some of these lines can also be obtained from the Curator, USDA Small Grains Collection, Bldg. 046, BARC-West, Beltsville, MD 20705 (Jodon 1977).
