Below are given the results of a backcross test with Golden 2 against translocation 3-7b. In the light of our earlier report (M.G.C. N.L., 3-23-37, p. 14) that g2 was possibly linked with d, the indication is that g2 is in chromosome 3. Chromosome 7, however, is not excluded.

  T+ Tg2 ++ +g2  
g2 139 19 19 160 = 337

Percent recombination = 11.3
