The inheritance of a second gene for the control of the brachytic stem trait in soybeans, Glycine max (L.) Merr., was studied. This recessive gene, designated sb 2 , was found in the brachytic‐stemmed line, PI 227224, when it was crossed with the normal‐stemmed cultivar, ‘Davis.’ Classification of plants in the F 1 , F 2 , and F 3 generations indicated two recessive gene pairs were involved in the expression of the brachytic trait. The results indicated that sb 2 is at a different locus than Sb , sb . Thus, it is suggested that the first locus should now be called Sb 1 , sb 1 to distinguish it from the second locus, Sb 2 , sb 2 .
