摘  要：
选用9个含有云南甘蔗野生血缘的创新材料作为父本,与31个国内外不同类型的母本进行杂交,获得38个杂交组合。参照澳大利亚家系试验方法,借助R软件,分析了创新亲本及家系的经济育种值和经济遗传值。结果表明:9个创新亲本中,云瑞04–48和云瑞03–393的经济育种值最高,作为父本应该重点加强利用;云瑞05–171和云瑞05–704可根据育种规模适当使用;38个家系中,MY57–62×云瑞03–393、Lho83–153×云瑞04–48、崖城71–374×云瑞05–171、RB85–5156×云瑞03–393、VMC96–60×云瑞05–704、M336×云瑞03–393等家系的经济遗传值较高,可作为选育优良甘蔗新品种的重点家系,建议降低选择强度,避免优良单株漏选。

摘  要：
A total of 38 cross combinations were obtained by crossed from using 9 innovated materials as male and 31 different kinds of materials from home and abroad as female. The economic breeding value and economic genetic value of male parents were evaluated by means of Australia family evaluation test and R software. The results showed that the economic breeding value of Yunrui04–48 and Yunrui03–393 were the highest among the 11 male parents, and they were proposed for frequent use. That of Yunrui05–171 and Yunrui 05–704 was higher and should be used appropriately according to the breeding scale. Among these 38 families, the economic genetic value of MY57–62×Yunrui03–393, Lho83–153×Yunrui04–48, Yacheng71–374×Yunrui05–171, and RB85–5156×Yunrui03–393 were relatively higher. They could be considered as the most important families for variety breeding with low selection intensity to avoid missing superior clones.
