BGS 78, Mottled leaf 4, mtt4
Stock number: BGS 78
Locus name: Mottled leaf 4
Locus symbol: mtt4
Previous nomenclature and gene symbolization:
Mottled leaf-e = mt,,e (3).
Mottled leaf = mt (6).
Mottled leaf = mt (6).
Inheritance:
Monofactorial recessive (3, 4, 5).
Located in chromosome 2HL (3, 5); mtt4.e is about 13.7 cM distal from the vrs1 (six-rowed spike 1) locus (3, 5); mtt4.e is associated with SNP markers 2_1340 to 2_0182 (positions 166.06 to 185.53 cM) in 2H bins 11 to 12 of the Bowman backcross-derived line BW602 (1), likely in 2H bin 11.

Description:
When the plants are grown under cool conditions, white-yellowish blotches develop as horizontal bands in seedling leaves, 2 to 4 per leaf blade (3). The bands faded as the plant grows or under warmer environmental conditions. At later stages of development, plants had a slightly yellow-green color (2). Plants of the Bowman backcross-derived line for mtt4.e, BW602, headed a few days later than Bowman, had 2 to 3 more kernels per spike, were slightly shorter, had slightly lighter kernel weights. The grain yields of BW602 were similar to those of Bowman (2).
