BGS 695, Necroticans 24, Nec24

BGN  43:198
Stock number: BGS 695
Locus name: Necroticans 24
Locus symbol: Nec24

Previous nomenclature and gene symbolization:



Monofactorial dominant (1).
Location is unknown.


The plants produce large dark brown spots on the leaf blades. The necrotic spots are not surrounded by chlorosis, but do show a little spreading. The phenotypic expression is similar to that of (Necroticans 22) (FN368, GSHO 3627), but the spots tends to fade more on older leaves (1). Allelism between and mutants has not been checked. The mutant is not allelic to the Nec26.ay (Necroticans 26) mutant (FN451, GSHO 3631) (1).

Origin of mutant:

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

Mutational events: (FN371, GSHO 3629) in Steptoe (CIho 15229) (1).

Mutant used for description and seed stocks: (FN371, GSHO 3629) in Steptoe.
