中文摘要：

利用30个云瑞创新亲本与国内外引进甘蔗品种选配的36个组合及双对照,分析组合后代9个主要农艺性状的遗传效应。结果表明：1云瑞创新亲本及组合对后代的影响存在显著性差异;2所用亲本的遗传力表现明显不同,其中株高、茎径、有效茎数、空心这4个性状表现优异,并在组合、父本和母本中的遗传力均大于50%;3一般配合力表现优异的材料有作为母本的云瑞05–628、云瑞03–417和作为父本的云瑞05–783、云瑞99–155、云瑞05–282、云瑞05–782、云瑞05–679;4特殊配合力较好的组合有高产、高糖型组合ROC20×云瑞05–282、SP71–6180×云瑞99–155和农林03–1×云瑞05––783,有高产型组合CP8×云瑞05–782、云瑞05–628×Zopilata,还有高糖型组合Q166×云瑞05–679、农林03–1×云瑞05–160。

英文摘要：

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; ③among 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, SP71-5180×Yunrui99-155 and Nonglin03-1×Yunrui05-783; High yield combinations were CP8×Yunrui05-782 and Yunrui05-528×Zopilata; and high sugar content combinations were Q 166×05-679 and Nonglin03-1×Yunrui05-160.
