BGS 138, Necrotic leaf spot 4, nec4
Stock number: BGS 138
Locus name: Necrotic leaf spot 4
Locus symbol: nec4
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2, 3, 5).
Located in chromosome 3H (2, 5); nec4.f is associated with SNP markers in both arms of 3H and the long arm of 2H of the Bowman backcross-derived line BW631 (1).
Located in chromosome 3H (2, 5); nec4.f is associated with SNP markers in both arms of 3H and the long arm of 2H of the Bowman backcross-derived line BW631 (1).
Description:
Small black spots develop on the leaves (2, 5). The spots persist until maturity, but they do not appear to reduce plant vigor (4).
