Methods and compositions for producing brachytic corn plants

A method for selecting a corn plant or seed, said method comprising:

• a) crossing a first corn plant comprising a brachytic allele at a polymorphic locus with a second corn plant to produce a population of progeny corn plants or progeny seeds
• b) conducting a marker assay to detect in said progeny population of corn plants or progeny seeds a progeny corn plant or progeny seed comprising said brachytic allele at a polymorphic locus, wherein said B polymorphic locus comprises SEQ ID NO:
• 7 having a thymidine (T) at position 72;
• and
• c) selecting said progeny corn plant or progeny seed comprising said brachytic allele.
