title: [Studies of chromosome Ag-NORs of Xianju chickens and the relation with the productive performance].
abstract: By using the method of culturing peripheral blood, Ag-NORs patterns of Xianju chickens were investigated. The results are as follows:Xianju chickens' Ag-NORs were located in 1p,3p,4p,Zp and 2q. The mean value per cell was 3.26 and the mode was 3. The size, the number and distribution between different individuals or of the same individual were polymorphic,and associations of Ag-NORs were found. Performances between two groups with different Ag-NOR frequency were not significantly different(P>0.05) except shank length in Xianju cocks.
