Abstract:
1. A method for screening genomic DNA fragments capable of providing plants with an agriculturally advantageous phenotypic variation, comprising the steps of: 1) preparing genomic DNA from a donor plant that has not been pre-selected for a particular phenotype, which is then cloned into a cloning vector to form a genomic DNA library, with the proviso that the step does not include a preliminary selection step of the genomic DNA fragments; 2) introducing the genomic fragment from each of the genomic clones constituting the genomic DNA library separately and randomly into a recipient plant that has not been pre-selected for a particular phenotype to produce transgenic plants; 3) cultivating the transgenic plant or progeny thereof to select a plant exhibiting an agriculturally advantageous phenotypic variation; 4) selecting the genomic DNA fragment, which was introduced in step (2) into the plant selected in step (3), as a purposed genomic DNA fragment; and 5) isolating and reintroducing the genomic DNA fragment selected in step (4) or a part thereof into another plant of any species to produce a plant; and 6) cultivating the plant of step 5) to select a plant exhibiting said agriculturally advantageous phenotypic variation.
