Hybrid Embryo Rescue in Crop Improvement

摘要: Failure to produce a hybrid may be due pre- or post-fertilization incompatibility barriers. The embryo, if produced, abort before maturation. In such cases, the embryo resulting from interspecific intergeneric crosses can potentially rescued and cultured whole plant, thus facilitating transfer of desirable genes wild relatives into cultivated species. This approach is especially warranted in horticultural crops situations where one both parents seedless, initial fruitlet drop very high, endosperm inimical, etc. Protocols have been developed for rescue several top-of-the-line fruit suffering an inability breed naturally wide crosses. Techniques figure among important commercially applicable breeding strategies under non-GM biotechnologies. It nonconventional, tissue culture-based technique used creating new genotypes, often plant embryos aborting progeny ovules/seeds. Distant are sought genetic traits secondary tertiary gene pools cultivated, primary pool crop plants.
