1. A method for directing plant embryos from a first upstream fluid conduit to one of at least two downstream fluid conduits, the method comprising:

  • (a) transporting plant embryos serially in a fluid carrier in an upstream fluid conduit, said upstream fluid conduit having an inner diameter that is small enough to ensure that the directional orientation of the embryos is maintained and the embryos pass through the upstream fluid conduit serially;

    (b) obtaining information regarding a plant embryo at a location in the upstream fluid conduit; and

    (c) selectively delivering the plant embryo to one of the at least two downstream fluid conduits according to the information by substantially aligning an end of the upstream fluid conduit with an end of one of the at least two downstream fluid conduits.
