Abstract According to GriffingⅢ, 30 crosses involving 6 inbred lines were made to analyze the combining ability and heritability of germination rate in the pod of Chinese cabbage（Brassica campestris L. ssp. pekinensis）. The results showed that the variance of specific combining ability was equal to that of the general combining ability. The germination rate in pod was affected by its parent genetic basis. It was controlled both by gene additive effect and non-additive effect and was influenced both by nuclear gene and cytoplasmic gene with less broad sense heritability and narrow sense heritability. But it was more affected by environmental conditions. We suggested that early generation selection should be done according to phenotype within expanded group of plants.
