BGN  43:207
Stock number: BGS 704
Locus name: Necroticans 33
Locus symbol: nec33

Previous nomenclature and gene symbolization:



Monofactorial recessive (1).
Location is unknown.


Small black spots appear on the leaf blades, leaf sheaths, and awns of mutant plants. The spots are similar to those produced by mutants at the nec1 (necrotic leaf spot 1) locus, but spots of the mutants appear in distinct linear rows and leaf blades show tip necrosis (1). The mutant is not allelic at the nec1 locus. The plants headed very late when grown at the Washington State University Agronomy Farm near Pullman, WA, USA (1).
