BGS 73, Angustifolium-a, fol-a
Stock number: BGS 73
Locus name: Angustifolium-a
Locus symbol: fol-a
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2), but heterozygotes can be identified based on leaf width.
Located in chromosome 2HL (2, 5); fol-a.1 is close to the vrs1 (six-rowed spike 1) locus based on linkage drag (4); fol-a.1 is associated with SNP markers 1_0214 to 1_1250 (positions 150.96 to 161.08 cM) in 2H bins 10 to 11 of the Bowman backcross-derived line BW370 (1).

Description:
Most organs are reduced in size. Plants have narrow, dark green leaves and a stunted, grassy growth habit (2, 5). Plant height is about 2/3 normal and spikes are 1/2 normal. Spikelets are about 2/3 normal size and the kernels were thin under greenhouse conditions (3). Plants of the Bowman backcross-derived line for fol-a.1, BW370, were slightly shorter than Bowman and leaf blades were about 1/2 normal width, 5 vs. 9 mm, and relatively short. Rachis internodes of BW370 were shorter 4.4 vs. 4.9 mm, kernels were smaller and 10 to15% lighter, but grain yields were slightly higher (3). BW370 plants lodged easier than Bowman (3).
