The casing is provided with a seed receiving zone in communication with a inlet, and a seed discharge zone in communication with an outlet. The casing is also provided with a stationary camming surface. The first disc is provided with a plurality of spring biassed selector pins. Each pin has an engagement surface and a cam follower surface. The cam follower surface engaging the camming surface. The second disc which rotates with and is parallel to the first disc is provided with a plurality of seed cells corresponding to the selector pins. A flexible and resilient membrane covers the seed cells. In operation, the discs are continuously rotated through the seed receiving and discharge zones. As a selector pin is driven towards the corresponding seed cell by the camming surface, the pin traps a single seed in the membrane covered seed cell. The seed is released when the pin is rotated into the discharge zone.
