To Our Maize Genetics Colleagues,

We are growing materials that you may wish to come and screen this 
summer.  At Illinois, material to screen includes EMS mutagenized and 
Mu transposon tagged MTM material, as well as a collection of 
genetically diverse inbred lines.  At Purdue, EMS mutagenized 
material in a different genetic background is growing.

All maize scientists in public and private sectors are invited to 
participate in screening for mutants and natural variants.

The materials at Illinois were planted on May 2, 3 and 4 and can be 
screened anytime now and throughout the summer.  Seedling mutant 
notes have been taken.

EMS  2784 total rows 326 mutants observed.

Mutants by pedigree, These are M2 families

A632   		239 families  55 mutants

A632xOh43   	414 families  80 mutants

Oh43xA632   	264 families  56 mutants

Mo17xA632  	178 families  33 mutants

A619xB73     	415 families  102 mutants

Some of the EMS materials will begin to flower by the end of June, 
but a majority of them will not be flowering  for another 10-14 days.


MTM material  1881 families  203 mutants

The MTM material appears that it will not  be flowering for another 10-14 days.


Maize Diversity Lines   300 families

Three of these lines have started shedding and different lines will 
shed pollen at various points over the entire summer, with the 
majority by about July 15 or so.

We have a dedicated computer on the farm for computer-based entry of 
all notes.  This can be accomplished either locally or remotely.


The EMS material at Purdue was planted May 4, May 11, May 23, May 31.

In total there are 1400 W22 M2 families out and 2500 W22 M1 if people 
want to look for dominants.

At Illinois, we have rented a large townhouse for the month, close to 
the field, that visitors from the Inflorescence project will be 
using. If not full at the time, overnight visitors are welcome to use 
this.  Purdue is only 90-100 miles from U. Illinois, they are within 
easy driving distance of each other.

Regards,
