Crosses 1 = Ch × C-S; 2 = cn × Cy/Pm; 3 = Ch × M-5; 4 = cn × C-S; and 5 = Ch × b lt rl cn, in which Ch = Charolles and C-S = Canton-S. The following EMS-induced alleles representing 13 genetic loci mapping to the heterochromatin of chromosome 2 were used in complementation tests: 56-8, 56-32, 56-3, 40-7, 56-4, 56-24, and 40-5 for 2Lh and 45-10, 31, 64, 45-17, 34-25, and EMS 45-75 for 2Rh.
