Saranac' alfalfa (Bingham, 1968) and trisomics at the diploid (2n = 2x + 1 = 17) and tetraploid level are easily recovered following triploid x diploid and triploid x tetraploid crosses, respectively (Stanford, 1959; Kasha and McLennan, 1967; Buss and Cleveland, 1971; Binek and Bingham, 1970; and reviewed by McCoy and Bingham, 1988).
Primary trisomics can be used to locate a gene on a particular chromosome, verify the independence of linkage groups, and associate linkage groups with individual chromosomes.
