BGS 422, Eceriferum-zd, cer-zd

None.

Monofactorial recessive (8).
Located in chromosome 3HL (2, 9); cer-zd.67 is about 9.4 cM proximal from the uzu1 (uzu 1) locus (10, 11, 12, 13); cer-zd.67 is about 4.6 cM distal from the breakpoint in the ert-c.1 (erectoides-c) line (10, 11, 12, 13); cer-zd.67 is associated with SNP markers 1_0672 to 1_0281 (positions 58.56 to 98.41) in 3H bins 04 to 06 of the Bowman backcross-derived line BW160 (1), likely in 3H bin 05. The BW160 line for cer-zd.67 had only three crosses to Bowman; thus, probably unassociated DNA segments with donor parent markers were retained in chromosomes 1H, 3HL, 5HS, 5HL, and 7H (1, 3).

Surface wax coating on the leaf blade appears absent (wax code ++ ++ -) (8). Concerning the chemical epicuticular wax composition, the amount of wax cm-2 is reduced and is accompanied by a decrease of the size and morphological complexity of the wax bodies. The bodies are smaller, simpler, and less dense. The wax class distribution is the same as in the mother cultivar (14). Plants of the Bowman backcross-derived line for cer-zd.67 (BW160) were 10 to 15% shorter than Bowman and headed about 2 days later. Kernels of BW160 were slightly thinner and 10 to 15% lighter. Grain yields were about 2/3 of normal (3)
