pedigree system
1.Early maturity maize inbred line Xinzi 224-1 is developed from the component(CM109×ZPL2-1-8) of inbred lines by Institute of Grain Crops of Xinjiang Academy of Agricultural Sciences. The basic germplasm is introduced from Yugoslavia. Xinzi 224-1 was selected after 7 generations selfing through pedigree system from F_2 population.
2.How to make clear the genetic pedigree and establish reasonable breeding system is the urgent issues. So we use the microsatellite DNA markers and non-invasive technology to research on the genetic diversity of captive Amur tiger in this study. ?Ten microsatellite loci (Fca005,Fca075,Fca094,Fca152,Fca161,Fca294,Pti002,Pti003,Pti007 and Pti010),highly variable nuclear markers,were studied their genetic diversity in 113 captive Amur tigers.
5.Abstract: The Huizhou ancient village and Shuikou Garden are chosen as the research target to analyze the causes of origin of cultural landscape from the aspects of their pattern, water system, and humanistic landscape on the basis of the study of geomancy recorded in the pedigree of clans and local chronicles.
