Sugarcane (Saccharum spp.) is the most significant global sugar crop, contributing approximately 80% of total sugar production worldwide. Developing high-yielding and high-sugar-content varieties is critical for enhancing sugar industry sustainability. To support this goal and optimize hybrid breeding strategies, this study evaluated 71 sugarcane hybrid combinations derived from 75 parental lines, using six key agronomic traits: plant height, stalk diameter, brix (juice sugar content), number of effective stalks, cane yield and sugar yield. The main objective was to assess general combining ability (GCA) and specific combining ability (SCA), to identify superior parental lines and hybrid combinations for sugarcane breeding programs. The GCA/SCA analyses were performed using the R software. Clustering analyses were conducted based on combining ability values to classify parental materials and hybrid combinations into distinct genetic performance groups. Results showed substantial genetic variation across hybrids, particularly in yield-related traits, with coefficients of variation exceeding 39.00% for effective stalks, cane yield and sugar yield, highlighting significant breeding potential. Conversely, brix exhibited the lowest variation (8.05%), indicating high genetic stability for sugar content traits. Notably, HoCP05-902, GT96-211, YT93-124, YT93-159, GT00-122 and YR05-704 were identified as elite male parents, while GT94-119, CP72-1210 and Eros were outstanding female lines. Two combinations, CP72-1210×GT96-211 and GT94-119×YT93-159, exhibited superior GCA and SCA values, achieving excellent performance in both yield and sugar content. Additionally, GCA/SCA ratio analysis revealed that cane yield exhibited significant additive effects primarily inherited from the male parent. In conclusion, this research provides valuable theoretical guidance and genetic resources for sugarcane breeding, highlighting key parental lines and hybrid combinations that can serve as core materials in developing next-generation high-yield, high-sugar sugarcane cultivars.

甘蔗（Saccharum spp.）是全球最主要的糖料作物，承担着约80%的世界食糖生产任务。为满足现代糖业对高产高糖甘蔗品种的迫切需求，本研究以71个甘蔗杂交组合的实生苗为材料，开展了株高、茎径、锤度、有效茎、蔗产量和糖产量6个农艺性状的遗传变异分析，并应用R软件对一般配合力（GCA）和特殊配合力（SCA）进行估算，同时基于蔗产量和锤度GCA与SCA进行聚类分析。结果表明：各组合在6个性状上均表现出丰富的遗传多样性，尤其在产量相关性状（有效茎、蔗产量和糖产量）上变异系数超过39.00%，展现出较大的选育潜力，糖分性状锤度的变异系数最低（8.05%），说明其受遗传控制较强，稳定性较高。筛选出优良父本HoCP05-902、桂糖96-211、粤糖93-124、粤糖93-159、桂糖00-122及云瑞05-704，优良母本包括桂糖94-119、CP72-1210和Eros等；组合CP72-1210×桂糖96-211与桂糖94-119×粤糖93-159在6个性状上均表现优异，兼具高产与高糖特性，是育种应用的核心组合。GCA/SCA比值分析指出，蔗产量的加性遗传效应主要由父本主导。本研究筛选出一批优质亲本和优势组合，为甘蔗高产高糖育种提供理论基础和实践路径，具有重要的应用前景。
