BGS 81, Glossy sheath 7, gsh7
Stock number: BGS 81
Locus name: Glossy sheath 7
Locus symbol: gsh7
Previous nomenclature and gene symbolization:
Glossy sheath 7 = gs7 (3).
Inheritance:
Monofactorial recessive (3).
Located in chromosomes 1H, 2HL or 5H (1); based on segments of the donor parent chromosomes retained in the Bowman backcross-derived line fror gsh7.ae (BW410), possible locations based on SNP markers included 1_0259 to 2_0229 (positions 70.78 to 106.61 cM) in 1H bins 07 to 10, markers, 1_0916 to 2_0681 (positions 187.68 to 247.86 cM) in 2H bins 12 to 15, markers 1_0580 to 1_0955 (positions 54.27 to 69.76 cM) in 5H bins 03 to 04, and markers 2_0367 to 2_1445 (positions 116.66 to 134.85 cM) in 5H bins 07to 08 (1).

Description:
The spike, leaf sheath and stem of mutant plants are glossy and bright green in color (wax code - - ++) (3). In early generation backcrosses to Bowman, the glossy sheath 7 segregates headed early and had poor vigor and small spikes. Also, spikes frequently abort after emasculation (2). Plants of the Bowman backcross-derived line for gsh7.ae (BW410) were 2/3 to 3/4 of normal height. Kernels are slightly longer and thinner than those of Bowman, and kernel weights are about 2/3 of normal. Grain yields are less than 10% of normal (2).

Mutational events:
gsh7.ae (GSHO 1759) in Akashinriki (PI467400, OUM022) (3).
Mutant used for description and seed stocks:
gsh7.ae (GSHO 1759) in Akashinriki; gsh7.ae in Bowman (PI 483237, NGB 22812)*5 (GSHO 2269, BW410, NGB 20643).
