Dear Colleague:
A photocopy of the paper you requested is in the mail. Because I do 
not know the answer to your question about pairs of spikelets and row 
irregularity, I am forwarding your email to the maize net for others 
to consider and respond.

Dear Prof. Coe,
Could you please send me a copy of your article 'Clonal analysis of 
corn plant development. I. The development of the tassel and the ear 
shoot' published in Dev Biol. 1983 May; 97(1):154-72. I hope your 
article will help me to answer some questions arisen under 
determination of the timing of the rbg reversion from the o2 allele. 
(The data on ear morphology available at the MNL web site (IMP) was 
very useful for me.) During this analysis I determined the 
appurtenance of revertant kernels to a particular spikelet by marking 
attachment places of revertant kernels and subsequently cutting off 
spikelet ear tissue remnants. Such a quite simple determination 
appeared to be more difficult on the ears with 'irregular' rows. One 
of the arising questions is whether the additional spikelets (which 
provoke row irregularity) always develop as a PAIR of spikelet or 
not. Do you have any information on this issue?
  Thank you in advance.    Sincerely yours,
     Vladimir V. Koterniak
