BGS 688, Necroticans 17, nec17

BGN  43:191
Stock number: BGS 688
Locus name: Necroticans 17
Locus symbol: nec17

Previous nomenclature and gene symbolization:



Monofactorial recessive (1).
Location is unknown.


Numerous brown spots of various sizes develop on older leaf blades of mutant plants. The vigor of nec17.ap plants is poor. The nec17.ap mutant is not allelic to the necrotic leaf spot 1 gene (nec1.a, GSHO 989, BGS 222) and necroticans 15 ( (GSHO 3620, BGS 686). It is phenotypically very different from other named necroticans (nec) genes (1).
