BGS 179, Hairy leaf sheath 1, Hsh1

BGN  44:107
Stock number: BGS 179
Locus name: Hairy leaf sheath 1
Locus symbol: Hsh1

Previous nomenclature and gene symbolization:

Hairy leaf sheath = Hs (9).


Monofactorial dominant (6, 7, 8).
Located in chromosome 4HL (8), Hsh1.a is over 8.7 cM proximal from the yhd1 (yellow head 1) locus, and over 22.5 cM distal from the mlo (reaction to Erysiphe graminis hordei-o) locus (5, 7); Hsh1.a is about 1.1 cM proximal from RFLP marker HVM067 in 4H bin 12 (2); Hsh1.a is associated with SNP markers 1_1066 to 1_1186 (positions 171.3 to 181.4 cM) in 4H bin 12 of the Bowman backcross-derived line BW416 (1), in 4H bin 12.


Short hairs (1 to 3 mm) are scattered or in rows on leaf sheaths of the basal part of the plant. The density of hairs varies considerably among cultivars and with changes in growing conditions. With few exceptions, no hairs are observed on the sheath of upper leaves (6, 7). Heterozygotes and smooth awned cultivars seem to have fewer hairs (4). Except for leaf sheath pubescence, the Bowman backcross-derived line for Hsh1.a, BW416, was similar morphologically and agronomically to Bowman (4).

Origin of mutant:

Natural occurrence in a few cultivars and in many accessions of Hordeum vulgare subsp. spontaneum (1, 7, 8).

Mutational events:

Hsh1.a was introduced into cultivated barley from its wild progenitor (7).

Mutant used for description and seed stocks:

Hsh1.a in Kimugi (GSHO 986, OUL012) (7, 8); Hsh1.a from R.I. Wolfe's Multiple Dominant Marker Stock (GSHO 3450) in Bowman (PI 483237)*10 (GSHO 2026, BW416, NGB 20649).
