Summary
The frequency of sesquidiploid hybrids amongst the progeny of single turnip (B. campestris) plants following their isolation, in insect cages, with single rape (B. napus) plants confirms that the self in compatibility system of the former is sufficient to ensure interspecific hybridisation without resorting to hand pollination. The sesquidiploids performed favourably in a small scale yield trial and their possible production as alternatives to true rape is discussed.
