BGS 695, Necroticans 24, Nec24
Stock number: BGS 695
Locus name: Necroticans 24
Locus symbol: Nec24
Previous nomenclature and gene symbolization:
Monofactorial dominant (1).
Location is unknown.
The Nec24.aw 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 Nec22.au (Necroticans 22) (FN368, GSHO 3627), but the spots tends to fade more on older leaves (1). Allelism between Nec22.au and Nec24.aw mutants has not been checked. The Nec24.aw 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).
Nec24.aw (FN371, GSHO 3629) in Steptoe (CIho 15229) (1).
Mutant used for description and seed stocks:
Nec24.aw (FN371, GSHO 3629) in Steptoe.
