Claims11
A plant comprising a mutated CENH3 gene, wherein the mutated CENH3 gene encodes a mutant CENH3 polypeptide having a CENH3 tail-domain and a CENH3 histone-fold domain, wherein the mutant CENH3 polypeptide is identical to a wildtype CENH3 polypeptide but for 1-7 amino acid substitutions that occur in the CENH3 histone-fold domain, wherein the plant comprising the mutated CENH3 gene, when crossed with a wildtype diploid plant, generates haploid progeny.
