1. The character previously listed as threaded (th) has been found to be allelomorphic to striate (sr). An F2 population segregating for f1, bm2, and sr gave a recombination per cent of 25 for bm2 and sr, 25.5 for sr and ts2. The recombination percentage for sr and f1 was 59, or no linkage. This seems puzzling since ts2 and bm2 are 128 units apart. However, the population was small consisting of but 59 plants.
