BGS 158, Yellow head 1, yhd1
Stock number: BGS 158
Locus name: Yellow head 1
Locus symbol: yhd1
Previous nomenclature and gene symbolization:
Yellow head = yh (5).
Inheritance:
Monofactorial recessive (4, 5).
Located in chromosome 4HL (4); yhd1.a is over 8.7 cM distal from the Hsh1 (Hairy leaf sheath 1) locus (3, 4); yhd1.a is associated with SNP markers 1_0712 to 2_0013 (positions 170.17 to 183.54 cM) in 4H bins 12 to 13 of the Bowman backcross-derived line BW920 (1).

Description:
The immature spikes appear ivory to pale yellow in color; the lemma is ivory-colored, but terminates into green tip with green awns; the plant has a whitish lower leaf sheath and ivory-colored culm nodes and rachis internodes (4). The pattern of reduced chlorophyll development is similar to the alm1 (albino lemma 1) mutants. Plants of Bowman-backcross-derived line for yhd1.a, BW920, headed and matured slightly earlier than Bowman and kernels were slightly lighter (2).
