Evidence from controlled crosses suggests, that male. sterility in kikuyu grass (associated with non-exsertion of stamens) is controlled by a single dominant gene, with fertility (exsertion of stamens) being recessive. Genetic dominance of male sterility influences the spread of kikuyu grass and the ways in which the genetic merit of indigenous pastures can be upgraded.
