BGS 139, Necrotic leaf spot 5, nec5
Stock number: BGS 139
Locus name: Necrotic leaf spot 5
Locus symbol: nec5
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2, 3, 5).
Located in chromosome 3H (2, 5), nec5.g is associated with SNP markers 2_0607 to 2_0410 (positions 52.41 to 61.77cM) in 3H bins 04 to 05 of the Bowman backcross-derived line BW632 and with SNP marker on all other chromosomes except 2H (1).

Description:
Circular dark brown spots develop on the leaves (2, 5). Leaf tissue in the large spots gradually darkens and dies, but plants vigor appears normal (4).
