This is also an En controlled C-Im(r) allele. When sectored kernels were crossed with the a1 En-tester, a-m(r)/a-m-1, sectored kernels were obtained and again crossed by a-m(r)/a-m-1, yielding sectored and colored progeny. When these were separated and again tested, the results of these tests were:
  With En No En  Total
Sectored 11 0 11
Colored 0 10  10

This allele as judged from tests on the En-tester responds to En. Both alleles are En-responsive and represent I inserts into C-I.
