Abstract: The invention provides novel methods to genotype haploid embryos using molecular assays. For example, quantitative methods for genotyping are provided. The methods provided also include providing a plurality of haploid kernels, determining the genotype of the haploid embryo of said kernels by distinguishing its genotype from the endosperm genotype, selecting a kernel having a desired genotype and producing doubled haploid plant from the selected kernel.

Abstract: Provided are methods for increasing the efficiency of creating doubled haploid plants by increasing the number of chances of forming a double haploid seed through treatment of a monocot plant with a plant growth regulator. In certain embodiments, maize plants are produced that comprise multiple co-dominant ears. Also provided are plants comprising the potential to generate increased numbers of doubled haploid offspring.

Abstract: Provided herein are delivery methods of a plant treatment agent to a tissue of a plant, wherein the tissue is contacted with a plant treatment agent and delivery is aided by a centrifugal force applied to the plant. Disclosed herein is the discovery that drastic improvements in treatment delivery occur when plants are centrifuged after being contacted, submerged, unsubmerged, soaked, etc. in a solution containing a plant treatment agent. In one embodiment, haploid plants contacted with a colchicine solution are centrifuged to reveal improved chromosomal doubling rates as compared to control plants.
