BGS 686, Necroticans 15, nec15

BGN  43:189
Stock number: BGS 686
Locus name: Necroticans 15
Locus symbol: nec15

Previous nomenclature and gene symbolization:



Monofactorial recessive (1).
Location is unknown.


Large dark brown spots develop primarily on older leaf blades. The spots may be surrounded by chlorosis and their gradual spreading results in death of older leaves. Mutant plants have good vigor (1). The mutant may be allelic to (FN452, GSHO 3632), but this needs to be confirm. It is not allelic to the necrotic leaf spot 1 (nec1.a) gene (GSHO 989), necrotic leaf spot 3 (nec3.d) gene (GSHO 1330), necroticans 10 (nec10.o) mutant (FN044, GSHO 3607), necroticans 11 ( mutant (FN227, GSHO 3610), necroticans 12 ( mutant (FN225, GSHO 3613), necroticans 13 (nec13.aj) mutant (FN360, GSHO 3616), necroticans 16 ( mutant (FN201, GSHO 3621), necroticans 17 (nec17.ap) mutant (FN242, GSHO 3622), and necroticans 19 ( mutant (FN327, GSHO 3624) (1).

Origin of mutant:

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

Mutational events: (FN093, GSHO 3620) in Steptoe (CIho 15229); (FN452, GSHO 3632) in Steptoe (1).

Mutant used for description and seed stocks: (FN093, GSHO 3620) and (FN452, GSHO 3632) in Steptoe.
