1. Three point test on chromosome 1, involving a new dominant tassel-seed, Ts6, originating from a 'freak ear' in the Iowa Corn Show about 9 years ago:
|+ + Ts6||93 83||94 59||1 1||0 1|
|br bm2 +||176||153||2||1||332|
Ts6 is recommended as a first class, useful marker exhibiting sharp segregation and producing good normal ears (rows characteristically irregular) when tassel is pulled early.
