该文报道了三峡库区 37个地方资源GiemsaC—带的多态性 ,在资源间与资源内部存在一定的多态性。C—带的分布与总数目各不相同。各地方资源GiemsaC—带总数在 4～ 1 3之间 ,但主要集中于 9左右。不同材料有不同的变异系数 ,选育自交系应考虑其变异系数
This paper reports the polymorphism of Giemsa C-band of 37 local resources in the Three Gorges Reservoir Area, and some polymorphisms exist between resources and resources. C-band distribution and the total number of different. The total number of Giemsa C-belts in various localities is between 4 and 13, but mainly around 9. Different materials have different coefficient of variation, breeding inbred lines should consider the coefficient of variation
