 Title    Segregation of Triazine-Resistant Chloroplasts after Introduction into Winter Type Oilseed Rape (Brassica napus L.) by Protoplast Fusion  
 Abstract    Triazine-resistant chloroplasts o f the Canadian spring oilseed rape variety OAC Triton were transferred into four German winter oilseed rape lines and two cultivars o f double-low quality by means o f protoplast fusion. X-irradiation has been used to reduce the am ount o f nuclear D N A o f the spring type cultivar and to promote cybrid formation. RFLP-analysis showed that some regenerants and their progeny carried both types o f chloroplasts. In som e instances regenerants and progeny containing mixtures o f both chloroplasts not kept under selective conditions lost their triazine-resistant chloroplasts completely during further plant growth. Preliminary results o f greenhouse and field experiments indicate that volunteer plants can be eliminated by application o f 1 5 0 -3 0 0 g/ha metribuzin (SencorR, Bayer A G) in a stand o f triazine-resistant oilseed rape o f double-low quality.
