BGS 680, Breviaristatum-v, ari-v
Stock number: BGS 680
Locus name: Breviaristatum-v
Locus symbol: ari-v
Previous nomenclature and gene symbolization:
Breviaristatum-137 = ari.137 (3).
Monofactorial recessive (3).
Located in chromosome 5HS (1); ari-v.137 is associated with SNP markers 2_1065 to 2_0265 (positions about 40.91 to 94.02 cM) in 5H bins 02 to 04 of Bowman backcrossed-derived line BW026 (1).
The mutant was selected as having slight shorter awns with weak calcariodes expression compared to the parental line Foma and a slight increase in plant height (3). The Bowman backcross-derived line for ari-v.137, BW026, was about 15% taller than Bowman, approximately 99 vs. 87 cm (2). The awns were 1 to 3 cm shorter than those of Bowman. Kernels of BW026 were 15% longer than those of Bowman and weighed 5 to 10% more. Grain yields of BW026 were similar to those of Bowman, but their test weights were slightly lower (2).
Origin of mutant:
An N-methyl-N-nitrosourea induced mutant in Foma (NGB 14659, CIho 11333) (3, 4).
ari-v.137 (NGB 115947) in Foma (NGB 14659, CIho 11333) (3, 4).
Mutant used for description and seed stocks:
ari-v.137 (NGB 115947) in Foma; ari-v.137 via ND15006 in Bowman (PI 483237)*5 (BW026, NGB 20412).
