BGN  26:403 Export to PDF
Stock number: BGS 451
Locus name: Eceriferum-yh
Locus symbol: cer-yh

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (3).
Located in chromosome 3HS (1); cer-yh.116 is based on linkage drag with the Btr1 (Brittle rachis 1) locus (1).

Description:

Surface wax coating on the spike appears absent (wax code - ++ ++) (3). Mutant plants are semi-sterile, heading is delayed, and lateral spikelets have a pointed apex. In the Bowman backcross-derived line, seed set is low because few hairs develop on the stigma. Although the anthers are slightly malformed, male fertility is good.

Origin of mutant:

An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (2).

Mutational events:

cer-yh.116 (NGB 111001, GSHO 1541), -yh.654 (NGB 111542) in Bonus (NGB 14657, PI 189763) (3).

Mutant used for description and seed stocks:

cer-yh.116 (NGB 111001, GSHO 1541) in Bonus; cer-yh.116 in Bowman (PI 483237)*5 (GSHO 1947, BW139, NGB 20545).
