The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

Trust property,in the common sense,should undertake independent and limited liability for all its business activities.The institution of trust registration is to proclaim the confine of the liable property to the public,and so the registration is the premise of the establishment of such liability institutions.The content of the registration should be on the property easy to be ascertained.The efficacity of the registration is mainly about the proclaiming and defense to the public.

信托登记制度共有三项功能：一是对第三人的宣示功能，告知不特定公众存在有信托财产及由此可能与其产生特别法上的权利义务关系；二是在委托人、受托人和受益人之间确认信托关系的功能，登记这一程序导致这种法律关系非经法定程序不可否认和改变；三是在管理当局和信托当事人之间发生法律上的认可功能，视信托关系是否合法，予以登记或拒绝，以保护公众利益。
