BGS 520, Male sterile genetic 48, msg48
Stock number: BGS 520
Locus name: Male sterile genetic 48
Locus symbol: msg48
Previous nomenclature and gene symbolization:
Male sterile genetic jt = msg,,jt and Msg76-5 (3).
Inheritance:
Monofactorial recessive (2, 3).
Probably located in chromosome 1H (1); msg48.jt is associated with SNP markers from 1_0744 to 1_0552 (positions 39.84 to 88.33 cM) in 1H bins 05 to 08 of a heterozygous plant from the Bowman backcross-derived stock BW585, plus small heterozygous regions in 4HL and 7HL (1).
Description:
Selfing - 5% (2), but it may be near 50% in certain environments.
Outcrossing - Complete female fertility (2).
Stamens - anthers slightly smaller than fertile sib with filament elongation, but no stomium (2).
