  • SORGHUM CYTOPLASMIC MALE STERILITY MARKERS AND LOCI
    Publication number: 20220340982
    Abstract: Various methods and compositions are provided for identifying and/or selecting a sorghum plant or germplasm with or without a cytoplasmic male sterility (CMS) trait. In certain embodiments, the method comprises detecting at least one allele of one or more marker locus within or linked to a QTL associated with CMS. In further embodiments, the method comprises crossing a selected sorghum plant with a recurrent sorghum parent plant and selecting progeny with CMS.
    Type: Application

  • Compositions and methods for enhancing resistance to anthracnose in grain sorghum
    Patent number: 10724109
    Abstract: Compositions and methods useful in identifying and selecting sorghum plants with increased resistance to anthracnose are provided herein. The methods use molecular genetic markers within QTL located on chromosome 5 and on chromosome 8 to identify and select plants with increased resistance to anthracnose, and plants comprising the QTL alleles associated with increased resistance to anthracnose can be crossed to other sorghum plants to incorporate the increased resistance into other sorghum lines or varieties.
