HYBRID BREEDING METHOD FOR FACULTATIVE APOMICTIC PLANTS

摘要

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.

1. A plant breeding method for the production of hybrid 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 an apomictic hybrid plant grown from said one or more F1 hybrid seeds; clonally propagating said apomictic hybrid plant to produce a cloned apomictic plant line; and growing one or more plants of said cloned apomictic plant line and collecting resulting apomictically-derived hybrid seeds from said grown plants, wherein said female parent is a tetraploid plant or an essentially self-incompatible diploid plant, and said male parent is an tetraploid plant or a hexaploid plant.
