摘要
A technique for the in vitro colchicine treatment of microspore-derived haploids of rape (Brassica napus L.) is presented. This allows effective and time-saving chromosome doubling. The most effective method consists of an application of 50 mg/l colchicine in a liquid B5 medium to the rooted microspore-derived plantlets for 4-8 days. By this treatment more than 50% of the plants developed at least diploid sectors. A change of medium after some days may even increase this diploidization rate.
