Two chromosomal interchanges have been reported in soybeans by Williams and Williams (1938) and Williams (1948). We have been using the chromosomal interchange reported in 1948, which came from a cross between Glycine soja (PI 101.4048) and G. max. We received seed in 1970 from R. L. Bernard (U.S . Regional Soybean Laboratory) of PI 101 .4048 x Clark as L68-7944-2.
