In term of analysis and comparison of differences on ornamental plants among UPOV 1991 and 1978 Convention, and Chinese Regulation on PVP, this paper focus on the specialty of PVP for asexual fruit crops and ornamental plants, and feasibility and advantage of UPOV 1991 Convention to them, such as essentially derived variety and farmers' privilege. Meanwhile, based on present situation of flower Industry development, breeding and creation, and world trade of floricultural crops, the author points out the opportunity and challenge of flower Industry development in China, and proposes a strategy of IPR and PVP on Chinese flower industry.

The extensive variation in chromosome number in root tip cells of three Chinese cabbage-cabbage monosomic alien addition lines with 21 chromosomes, 6-2-4, c-2-4 and d6, was obsevered after vegetative propagation multi-generations. The chromosome number varied from 17 to more than 50. The 25S rDNA signals were very complex in the three different clones.
