BGS 447, Eceriferum-yd, cer-yd

BGN  26:399
Stock number: BGS 447
Locus name: Eceriferum-yd
Locus symbol: cer-yd

Previous nomenclature and gene symbolization:



Monofactorial recessive (3).
Located in chromosome 3HS (1); cer-yd.139 is based on linkage drag with the btr1 (non-brittle rachis 1) locus (1).


Surface wax coating on the spike appears absent (wax code - ++ ++). The original cer-yd.139 stock has narrow leaf blades, pointed lateral spikelets, and semi-sterility (3). In the Bowman backcross-derived line, surface wax coating appears reduced (wax code + ++ ++). The Bowman backcross-derived line has few stigma hairs and very poor to slightly reduced seed set occurs in various environments, but male fertility is normal. Lodicules appear pistiloid in plants grown in the greenhouse.

Origin of mutant:

A gamma-ray induced mutant in Bonus (NGB 14657, PI 189763) (2).

Mutational events:

cer-yd.139 (NGB 111024, GSHO 1537) in Bonus (NGB 14657, PI 189763) (3).

Mutant used for description and seed stocks:

cer-yd.139 (NGB 111024, GSHO 1537) in Bonus; cer-yd.139 in Bowman (PI 483237)*4 (GSHO 1946); cer-yd.139 in Bowman*5 (BW135, NGB 20541).
