| Tassel has intermittent sections of fertile pistillate and normal staminate flowers. | Strong upper tassel branches, lower branches functionally complete ears with individual husks, silks and kernels. Also a strong ear in the normal position. Homozygotes have a cluster of leaves and primitive tassel in the standard position. |

| A mature tassel of a Ts*-H2651/+ heterozygous mutant plant from outcross by W23 showing an open-branched tassel covered with fuzzy abnormal female florets and prolific silks; top of main spike has scattered anthers with viable pollen. | A Ts*-2620/+ mutant plant from a cross on Mo20w showing a terminal inflorescence consisting of a strong tassel with branches at the tip surrounded at its base by a cluster of 5 fully formed ears with husks and fertile silks. Heterozygotes from crosses on other inbreds produce more typical simple Ts tassels |
