US 2026/0028642 A1 · HYBRID BREEDING METHODS FOR FACULTATIVE APOMICTIC PLANTS

Abstract

The present disclosure relates to materials and methods useful for improving the efficacy of a plant breeding program such as, for example, the method for producing hybrid seeds in a facultative apomictic crop species, which in turns are useful for, for example, commercial production of highly uniform hybrid progeny. Hybrid seeds produced by such improved breeding methods, and plant grown from such hybrid seeds are also within the scope of the present invention. The disclosure further relates to processes for making a plant-derived product derived from any of the foregoing hybrid plants, and plant-derived products produced by such processes.

Dependent claims

A guayule plant breeding method for the production of viable triploid or pentaploid guayule seed, said method comprising:

pollinating a female parent with pollen from a male parent to produce one or more F1 hybrid seeds on said female parent;
selecting a triploid or pentaploid apomictic guayule plant grown from said one or more F1 hybrid seeds;
vegetatively propagating said triploid or pentaploid apomictic guayule plant to produce a cloned apomictic plant line;
growing one or more plants of said cloned apomictic plant line in the presence of at least one tetraploid guayule plant thereby producing said viable triploid or pentaploid guayule seeds with the same genotype as said cloned apomictic plant line;
and
collecting said viable triploid or pentaploid guayule seeds from said one or more grown plants.
