BGN  43:217 Export to PDF
Stock number: BGS 722
Locus name: Breviaristatum-y
Locus symbol: ari-y

Previous nomenclature and gene symbolization:

Breviaristatum-9 = ari-9 (3).

Inheritance:

Monofactorial recessive (2).
Located in chromosome 5H (1, 2); ari-y.9 is linked to the raw1 (smooth awn 1) locus based on linkage drag (2); ari-y.9 is associated with SNP markers 1_1456 to 2_1177 (positions 195.82 to 203.85 cM) in 5H bins 10 to 11 of the Bowman backcross-derived line BW037 (1).

Description:

Plants of the ari-y.9 are smaller than Bonus in all vegetative organs and stature (3, 4). The size reduction of ari-y.9 plants was maintained in the Bowman backcross-derived line, BW037. The awn length of BW037 varied over environments, but averaged about 1/2 that of Bowman. The leaves were about 2/3 normal width and 3/4 normal length. Compared to Bowman, BW037 plants were 15 to 20% shorter, peduncles were 20 to 25% shorter, rachis internodes were slightly shorter, kernels per spike were 3 to 5 fewer, kernels were narrower, and kernel weights were low averaging 4.2 vs. 5.5 mg. Test weights of BW037 grain were lower and grain yields were 1/4 to 1/2 those of Bowman (2).

Origin of mutant:

A gamma-ray induced mutant in Bonus (NGB 14657, PI 189763) (3, 4).

Mutational events:

ari-y.9 (NGB 115854) in Bonus (PI 189763) (4).

Mutant used for description and seed stocks:

ari-y.9 (NGB 115854) in Bonus; ari-y.9 in Bowman (PI 483237)*6 (BW037, NGB 20445).
