Heredity effects of nine major characters were studied using two control varieties and thirty-six combinations coming from thirty Yunrui innovative parents and introduced sugarcane varieties. The results indicated that ① there were significant difference on the effects to offspring by each parent and their combination of Yunrui. ② the contribution of broad-sense heritability were different from height, diameter, stalk number and hole, and they were all greater than 50% in parents and their combinations; ③ among these parents, Yunrui05–628 and Yunrui03–417 as excellent female parents had good general combining ability (GCA), and Yunrui05–783, Yunrui99–155, Yunrui05–282, Yunrui05–782 and Yunrui05–679 as excellent male parents were better; ④ Several outstanding combinations with high yield and high sugar content combination were ROC20×Yunrui05–282, SP71–6180×Yunrui99–155 and Nonglin03–1×Yunrui05–783; High yield combinations were CP8×Yunrui05–782 and Yunrui05–628×Zopilata; and high sugar content combinations were Q166×05–679 and Nonglin03–1×Yunrui05–160.
