BGS 697, Necroticans 26, Nec26

BGN  43:200
Stock number: BGS 697
Locus name: Necroticans 26
Locus symbol: Nec26

Previous nomenclature and gene symbolization:



Monofactorial dominant (1).
Location is unknown.


The leaf blades of mutant plants develop extensive dark rust colored, spotty necrosis, which often covers older leaf blades completely leading to death. Little or no chlorosis around the necrotic lesions was observed. The Nec26.ay mutant is possibly allelic to (Necroticans 22) (FN368, GSHO 3627), but it is not allelic to (Necroticans 24) (FN371, GSHO 3629). Plants of the Nec26.ay stock have fair vigor (1).

Origin of mutant:

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

Mutational events:

Nec26.ay (FN451, GSHO 3631) in Steptoe (CIho 15229) (1).

Mutant used for description and seed stocks:

Nec26.ay (FN451, GSHO 3631) in Steptoe.
