The invention relates to a method and system for picking up and collecting plant matter, in particular plant embryos. To pick up the plant matter, a pick-up unit is used that is mounted to a robotic arm. According to the invention, two separate imaging steps are performed at two different positions of the pick-up unit. The first imaging step is performed to identify an isolated piece of plant matter. The second imaging step is performed when the pick-up unit is at a confirming position and enables a verification of whether a piece of plant matter has been picked up or not. The confirming position is in between the position of the pick-up unit for picking up plant matter and the position for depositing plant matter in suitable receptacles.

The present invention relates to a male sterile Rucola plant obtainable by a method which may comprise the steps of providing fertile pollen fromto the stamen of plants that contain CMS cytoplasm, allowing plant embryo's to develop, isolating the embryo's, raising the embryo's in tissue culture to produce plant lets, growing plants from the plantlets; selecting plants that are male sterile and female fertile; backcrossing these plants with fertile pollen from; selecting a plant that is male sterile and female fertile; and optionally repeating steps g) and h).
