<p>There is provided a method for transferring novel genetic materials into maize. The method for deriving these new genes is via wide cross hybrid plants produced by crossing two wild relatives of maize, Eastern gamagrass (Tripsacum) and perennial teosinte (Zea diploperennis). This invention thus relates to the novel genetic materials in hybrid seed, the hybrid plant produced by the seed and/or tissue culture, variants, mutants, modifications, and cellular and molecular components of Tripsacum-perennial teosinte hybrids, and the hybrid seed, the hybrid plant produced by the seed and/or tissue culture, variants, mutants, modifications, and cellular and molecular components of (maize X Tripsacum-perennial teosinte) and/or Tripsacum-perennial teosinte X maize). In particular this invention is directed to the ability to transfer de novo nucleotide sequences and novel alleles from Tripsacum to maize for use in genetic analyses and selection of novel genotypes with enhanced agronomic traits such as insect and disease resistance, drought tolerance, cold tolerance, tolerance to water-logging, apomixis, totipotency, perennialism, as well as adaptation to adverse soil conditions and a carbondioxide enriched atmosphere via (maize X Tripsacum-perennial teosinte) hybrids in corn improvement programs.</p> |
