The invention provides methods for producing plants, plant materials and seeds that have multiple desirable attributes for consumers of these products, as well as for commercial plant growers, and to improved plants, plant materials and seeds that are produced by these methods. These inventive methods provide hybrid plants, plant materials and seeds having the mutant shrunken-2i (sh2-i) allele incorporated into their genomes, preferably sequentially along with one or more other mutant alleles, such as the sugary- 1 (su1), sugary enhancer- 1 (se1) and/or shrunken-2 (sh2) alleles, and that have multiple beneficial traits, including an extended sugar retention ability at the post prime eating stage and a significantly enhanced vigor and fitness to the plant, plant material and / or seed during seed germination, seedling emergence from soil, and plant development.
