Pankaj,

I agree.

Also, leaf shape: broad.  See: 
http://www.maizegdb.org/db_images/Variation/coe0022-1683/038.jpg

d1 (Allele) d1, dwarf plants: three paired rows, left two untreated 
(rosettes reaching flowering), next two rows treated weekly with 
gibberellic acid (elongated and reaching flowering)
