| 摘 要： | 小麦主要经济性状大多属数量性状，是受
微效多基因控制的。为了探索小麦常用亲本配
制组合时各主要经济性状的遗传变异规律，于
1980年选用了江苏、浙江两省普遍采用的UP
301、泰山1号、908、早白、白壳早、短秆早6
个品种作为杂交亲本，研究并分析了主要经济
性状的遗传参数，为有效地选配亲本，提高育种
成效，提供一些理论依据。

| 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. |
