The genetic male sterile referred to as msg,,jt originated as a spontaneous mutant isolated by P. Hagberg from the cultivar Simba (Hockett, 1984). Hockett (1984) reported that msg,,jt is a simply inherited recessive gene which produced plants with nearly normal anthers and about 5% self fertility. Linkage studies indicated that msg,,jt is associated loosely with the V locus in chromosome 2 (Franckowiak, 1991).

Progeny from crosses between msg,,jt heterozygotes and lines homozygous for numbered male sterile genes demonstrated that msg,,jt is not allelic to msgl through msg47 (Table 1). The gene symbol msg48jt is suggested for the msg,,jt gene.
