Stock number: BGS 689
Locus name: Necroticans 18
Locus symbol: nec18
Previous nomenclature and gene symbolization:
Monofactorial recessive (1).
Location is unknown.
Expression of the nec18.aq mutant is first observed as a few small dark brown flecks on the leaf blades. Streaking of the numerous light brown to brown necrotic lesions occurs on older leaf blades of nec18.aq plants. The lesions spread resulting in death of leaf blades. The vigor of nec18.aq plants is fair (1).
Origin of mutant:
A fast neutron induced mutant in Steptoe (CIho 15229) (1).
nec18.aq (FN275, GSHO 3623) in Steptoe (CIho 15229) (1).
