BGS 630, Breviaristatum-s, Ari-s
Stock number: BGS 630
Locus name: Breviaristatum-s
Locus symbol: Ari-s
Previous nomenclature and gene symbolization:
Breviaristatum-265 = ari-265 (3).
Inheritance:
Monofactorial incomplete dominant (2).
Located in chromosomes 5H or 7H (1); Ari-s.265 is associated with SNP markers 2_1177 (position 203.85 cM) in 5H bin 11 and with SNP marker 1_1291 (position 107.44 cM) in 7H bin 07 of the Bowman backcross-derived line BW057 (1). Note that the expression of marker 1_1291 was variable among BW lines.

Description:
Awns of plants homozygous for the Ari-s.265 allele are about 1/3 normal length and slightly wider than those of normal sibs. The grain is wide and short and has a globose shape. Sterile lateral spikelets and glumes are about half normal length. Rachis internodes are shortened slightly, plants are 3/4 to 5/6 of normal height, and plant vigor is reduced (2). Awns of plants heterozygous for the Ari-s.265 allele were 3/4 normal length. A slight shortening of other parts of the spike was observed in heterozygotes (2). Compared to Bowman, plants of the Bowman backcross-derived line for Ari-s.265, BW057, were 10 to 15% shorter, their awns were about half as long, and rachis internodes were shorter, 3.7 vs. 4.5 mm. Kernel were short, 6.3 vs. 9.7 mm and about 40% lighter, 3.5 vs. 5.8 mg. Grain yields of BW057 were about 1/3 those of Bowman (2).
