Cytogenetic analysis of two chromosomal male-sterility mutants in hexaploid wheat

Abstract

The two chromosomal male-sterility mutants referred to as Pugsley's male-sterile and the Probus male-sterile fail to complement one another. Partial monosomic analysis revealed that both mutants are located on chromosome 4A. A strong homoeoallelic 'echo' was received from chromosome 4B with the Probus mutant, mslb, but not with Pugsley's mutant, msla. © 1975 ASEG.
