| 摘 要： | 该文报道了三峡库区３７个地方资源Ｇｉｅｍｓａ Ｃ－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Ｇｉｅｍｓａ Ｃ－带总数在４￣１３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。

| Abstract: | Polymorphism was observed within and between the 37 local accessions of maize (Zea mays L.) collected in the Three-Gorges Dam Area. The number of C-bands and their distribution differed with accession, varying between 4 and 13. Most of the accessions studied had about 9 bands. The accessions also showed different coefficients of variance, wlfich should be taken into account in breeding in-bred lines from these local germplasns. |
