GENERATION OF HAPLOID PLANTS

摘要

The present invention provides methods and compositions for generating haploid plants. The present invention also provides plants having an inactivated endogenous CENH3 gene and expressing a heterologous CENH3 polypeptide from another species. Typical breeding of diploid plants relies on screening numerous plants to identify novel, desirable characteristics. Large numbers of progeny from crosses often must be grown and evaluated over several years in order to select one. or a few plants with a desired combination o traits.
