Abstract
1. A recessive variation, called sorghum tassel, sgsg, which appeared in a selfed line of Rustler White Dent, is described. It resembles sorghum in the appearance of the tassel which contains both male and female florets. The ear has a characteristic irregularity of rows. 2. Sorghum tassel plants grow somewhat less vigorously than normal plants. From various crosses a total of 11.980 F2 plants was obtained. The percentage of sorghum tassel plants was 23.08 which is a significant deviation from 25, the percentage expected for a recessive character. 3. The linkage relation for sorghum tassel and eighteen other characters in known linkage groups were studied in F2. No definite indications of linkage were obtained. In a cross between sorghum tassel and tunicate, ears of “cauliflower” type were obtained in F2, these plants being homozygous for Tu. and sg. The plants homozygous for sg and heterozygous for Tu also gave some evidence of “cauliflower” tissue in the ears of some of the plants.
