3. Virescent seedling. A virescent seedling in Minn. #13 corn was found to be linked with japonica and given the symbol v21. Rhoades (Co-op News Letter, March 23, 1937) has found v16 and v21 to be allelic after trisomic tests had placed v16 also in chromosome 8. Further linkage data of j1, ms8 and v16 are as follows:
The order of the genes appears to be j1 - ms8 - v16.
