BGS 592, Yellow head 2, yhd2
Stock number: BGS 592
Locus name: Yellow head 2
Locus symbol: yhd2
Previous nomenclature and gene symbolization:
Yellow head 2 = yh2 (2).
Inheritance:
Monofactorial recessive (2).
Location is unknown; when yhd2.b is compared to Bowman, no polymorphisms were observed in the Bowman backcross-derived line for yhd2.b, BW921 (1).
Location is unknown; when yhd2.b is compared to Bowman, no polymorphisms were observed in the Bowman backcross-derived line for yhd2.b, BW921 (1).
Description:
The yhd2.b seedlings are slightly yellow-green compared to normal sibs. The lighter green color persists until after heading. The phenotype is similar to that expressed by some chlorina mutants. Plants of the Bowman backcross-derived line for yhd2.b, BW921, headed 3 to 5 days later than Bowman and were 5 to 10% shorter. Other morphological traits of BW921 including yield were not different from the range of values recorded for Bowman (3).

Origin of mutant:
A spontaneous mutant in Compana (PI 539111) (2).
Mutational events:
yhd2.b (Golden Compana, GSHO 757) in Compana (PI 539111) (2, 3).
Mutant used for description and seed stocks:
yhd2.b (GSHO 757) in Compana; yhd2.b in Bowman (PI 483237)*6 (GSHO 2037): yhd2.b in Bowman*8 (BW921, NGB 22350).
