We reported inheritance studies and linkage tests with T263 (Palmer, 1977), a line carrying a gene for dwarfness. We had not completed allelism tests with the other available dwarfs, df2, df3, and df4, at that time. In this report, we give the allelism test results, as well as results of linkage tests of T263 with y13, Y12, G, T, and a chromosome interchange from PI 101,404B (Glycine soja).
