BGS 337, Broad leaf 2, blf2
Stock number: BGS 337
Locus name: Broad leaf 2
Locus symbol: blf2
Previous nomenclature and gene symbolization:
Narrow leaf = nlh (4).
Broad leaf 2 = bb2 (6).
Narrow leaf-k = nl.k (2).
Broad leaf 2 = bb2 (6).
Narrow leaf-k = nl.k (2).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 5HL (2); blf2.b is based on linkage drag with the raw1 (smooth awn 1) locus (2); blf2.b is associated with SNP markers 2_0298 to 1_1490 (positions 203.85 to 235.18 cM) in 5H bins 11 to 12 of the Bowman backcrossed-derived line BW059 (1).

Description:
Leaf blade width of mutant plants is narrower (about 2/3 of normal) than those of Hannchen (5, 6). Leaf blades of plants of the Bowman backcross-derived line BW059 are 2/3 to 3/4 as wide as those of Bowman. BW059 plants are slightly shorter, have 2 to 3 fewer kernels per spike, and have slightly shorter and lighter kernels. Grain yields of BW059 were similar to those of Bowman (3).

Origin of mutant:
A neutron induced mutant in Hannchen (CIho 531) (5).
Mutational events:
blf2.b (GSHO 1667) in Hannchen (CIho 531) (4, 5, 6).
Mutant used for description and seed stocks:
blf2.b (GSHO 1667) in Hannchen; blf2.b in Bowman (PI 483237)*6 (GSHO 2136); blf2.b in Bowman*7 (BW059, NGB 20467).
