BGS 550, Breviaristatum-b, ari-b
Stock number: BGS 550
Locus name: Breviaristatum-b
Locus symbol: ari-b
Previous nomenclature and gene symbolization:
Breviaristatum-11 = ari-11 (3, 4).
Monofactorial recessive (4).
Location is unknown (1); ari-b.11 is associated with SNP molecular markers in large DNA segments of chromosomes 3H, 4H, and 5H of the Bowman backcross-derived line BW039 (1).
Plants are semidwarf with reduced viability and fertility; leaves are broad, but shortened and lighter green in color; and awns are about 3/4 normal length. Growth is markedly retarded during warm seasons and relatively good during cool seasons (4). Development of reproductive organs is delayed and sterility makes the Bowman backcross-derived line for ari-b.11, BW039, difficult to maintain (2). In field experiments, BW039 plants were about 2/3 the height of Bowman and headed 4 to 6 days later. Rachis internodes were short, 3.2 vs. 4.7 mm, peduncles were short, 22 vs. 32 cm, and flag minus one leaf blades were short, 14 vs. 20 cm. Awns of BW039 were 1/2 to 3/4 normal length. Kernels of BW039 were short, 8.3 vs. 9.6 mm, narrow, 3.6 vs. 3.8 mm, and weighed 1/2 to 2/3 of those for Bowman. Grain yields of BW039 were almost none (2).

Mutant used for description and seed stocks:
ari-b.11 (NGB 115856, GSHO 1649) in Bonus; ari-b.11 in Bowman (PI 483237)*3 (GSHO 2157, BW039, NGB 20447). (The NGB 20447 backcross derived line was segregating in the glasshouse in Lund and stored as a segregating stock).
