BGS 692, Necroticans 21, nec21

BGN  43:195
Stock number: BGS 692
Locus name: Necroticans 21
Locus symbol: nec21

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (1).
Location is unknown.

Description:

The mutant phenotype for nec21.at appears as small light brown, elongated spots on the leaf blades. Older leaf blades show a gradually developing necrosis at the base as spots enlarge and become more numerous. The vigor of mutant plants is fair (1). The nec21.at stock (FN367, GSHO 3626) also exhibited a light green color, which may be an associated mutation; however, it was not separated from the necrotic phenotype in a small population (1).

Origin of mutant:

A fast neutron induced mutant in Steptoe (CIho 15229) (1).

Mutational events:

nec21.at (FN367, GSHO 3626) in Steptoe(CIho 15229) (1).

Mutant used for description and seed stocks:

nec21.at (FN367, GSHO 3626) in Steptoe.
