摘要
The present invention relates to methods of obtaining fertile putative sorghum x maize and/or maize x sorghum intergeneric hybrid plants and plants produced thereby. In certain aspects, fertile putative sorghum x maize intergeneric hybrid plants are produced by crossing a sorghum parent plant NOT comprising a sorghum recessive mutant iap allele with pollen from a maize parent plants comprising a recessive mutant endosperm allele such as waxy1 (wx1) and/or opaque-2 (o2). In further aspects, the invention provides methods for the production of fertile putative maize x sorghum intergeneric hybrid plants and plants produced thereby. Specifically, fertile putative maize x sorghum intergeneric hybrid plants are produced by crossing a maize parent plant as female and comprising a recessive mutant endosperm allele such as waxy1 (wx) and/or opaque-2 (o2), wherein the mutant alleles maybe expressed in the homozygous single or double recessive state with pollen from a sorghum parent plant. The invention also provides methods for the development of subsequent filial generations of the putative F1 sorghum x maize and/or maize x sorghum intergeneric hybrid plant and plants thereof. Methods of utilising sorghum x maize and/or maize x sorghum intergeneric hybrid plants, progeny and products obtained therefrom are also provided.
