Linkage tests with ff.

Rick, C. M.

Information concerning origin, phenotype, and segregation of filicifolium (ff) need not be presented here since it was published in Jour. Hered. 50:91-98 (1959). But, as linkage data from all tests were not given in the latter, they are reported in the following table.
