Corn Genetics Question

I am trying to develop a non-majors general biology lab exercise that 
connects Mendalian genetics to an actual gene. My hope would be to 
use corn seed color. Carolina Biological sells corn cobs that 
students could count & see that the 3:1 ratio holds. I'd like to then 
have them plant the seeds, grow the plants and do PCR to show that 
the purple seeds which show one phenotype can have different 
genotypes whereas the yellow are all the same genotype. I have found 
the nucleotide sequence for the wildtype R1 gene but I don't know 
which r1 allele Carolina sells. Does anybody out there know which 
allele it is? Does anybody know of tested primers for the R1 & r1 
genes? I would sure appreciate any help you could give me.

Thanks,
