Phenotypic screen for plants

A method of identifying one or more transgenes that confer desired traits within a population of crop plants, the method comprising:

• a) preparing a seed mixture comprising seeds from a group of crop plant lines, the seed mixture comprising an equal number of seeds from each crop line;
• wherein each crop plant line comprises a unique transgenic event, said transgenic event comprising a genetic construct which comprises one or more transgenes;
• b) planting said seed mixture to produce a random plant population, wherein each seed in the mixture is planted;
• c) exposing said plant population to a common environment;
• d) evaluating the plants in said plant population to identify plants exhibiting one or more desired traits;
• and
• e) determining the presence of said one or more transgenes in said plants exhibiting said one or more desired traits.
