1. I have been studying an abnormal tassel type that I propose to call ramose tassel. It gives some variation in ear type. Some strains show crooked rows and generally a few sterile male florets on the tip of the ear. In other cases the upper half of the ear is divided somewhat like ramose-1. In crosses, however, either of these types can be separated from ra1 with considerable accuracy. Linkage studies of ramose tassel were made last year using F₂ data from crosses with representative genes of the ten groups. It is linked with na₁ cr₁ and py in group 3 [py is in group 6]. It has occurred to me that this may be the same factor or an allelomorph of ra₂ reported by Brink but not published. [Brink's linkage data (Linkage Summary, pp. 41, 42) give a₁-ra₂ 51% and ra₂-Rg 34% recombination.]
