Abnormal plants occur from time to time in cultivated fields of guar [ Cyamopsis tetragonoloba (L.) Taub]. Abnormalities due to genetic change have potential for use as genetic markers in a breeding program. A mutant having a rosette‐raceme and reduced fertility was found in a released breeding line, TX76‐328S, growing near Hluwe in Natal, South Africa. Inheritance of the rosette‐raceme trait was investigated. Rosette‐raceme was found to be inherited as a monogenic recessive and is expressed on every raceme. The name rosette‐raceme and the gene symbol, ros , are proposed for the new mutant trait. This trait should be useful in genetic studies as an easily identifiable phenotype.
