Research Notes: Linkage Studies with a Chromosomal Interchange
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.
