BGS 471, Male sterile genetic 34, msg34

BGN  45:181 Export to PDF
Stock number: BGS 471
Locus name: Male sterile genetic 34
Locus symbol: msg34

Previous nomenclature and gene symbolization:

Male sterile av = msg,,av (4).
Male sterile = 63msy1 (4).

Inheritance:

Monofactorial recessive (4, 7, 8).
Located in chromosome 6HS (2, 3); msg34.av is associated with SNP markers 1_0775 to 1_0744 (positions 26.42 to 39.34 cM) in 1H bins 03 to 05 in a homozygous plant from Bowman backcross-derived line BW570 (1). Previously recombination between msg34.av and the rob1 (orange lemma 1) locus was not observed (2).

Description:

Selfing - none (4).
Outcrossing - complete female fertility (4).
Stamens - anthers rudimentary, with no stomium or filament elongation (4).
Heterozygotes show reduced fertility (75 to 85% seed set), and male sterile plants always have a Long glume awn 1 (Lga1) trait from Paragon. Thus, the msg34.av mutant may involve a translocation between chromosomes 6HS and 7HS (3).

Origin of mutant:

A spontaneous mutant in Paragon (CIho 13649) (8).

Mutational events:

msg34.av (MSS314, GSHO 2386) in Paragon (CIho 13649) (5, 6).

Mutant used for description and seed stocks:

msg34.av (GSHO 2386) in Paragon; msg34.av in Bowman (PI 483237)*7 (GSHO 2070, BW570, NGB 24134).
