1. A branched ear was observed in F2 (1923) of the station strain of Reid's Yellow Dent. It appears similar in all respects to the one described by Kempton as branched silkless, bd, and was reported by Rhoades (Maize letter, November 24, 1934) to be allelomorphic to that gene. F2 data involving bd with two other genes show it to belong to group 7. [The data (see III, below) seem to place bd to the right of ij, near Bn1. Hadjinov's data (Linkage Summary, p. 57) give about 36% recombination between bd and Bn1. His bd has not been tested with either Bryan's or Kempton's.]
