了解甘蔗品种的产量潜力和稳产性，对指导甘蔗育种和合理布局甘蔗品种具有重要意义。采用遗传力调整的基因型主效应加基因型×环境（HA-GGE）双标图方法，分析了8个试验点44个甘蔗新品种的甘蔗产量和蔗糖产量。9个品种的蔗茎和蔗糖产量均高于对照品种新台糖22号。从甘蔗产量的角度来看，品种FN 40和YZ 06-407适应性较广，在几个试点获得了较高的甘蔗产量。从蔗糖产量的角度来看，LC 03-1137、FN 38、FN 41、MT 01-77和LC 05-136等品种适应性较强，蔗糖产量较高。据此，推荐FN 39、LC 05-136和YZ 05-51 3个高产、广适品种在我国3个主产区推广种植。研究结果将为我国甘蔗品种的有效利用和合理区域布局提供理论依据。
Knowing yield potential and yield stability of sugarcane cultivars is of significance in guiding sugarcane breeding and rationalising regional distribution of sugarcane cultivars. In the present study, a heritability-adjusted genotype main effect plus genotype x environment (HA-GGE) biplot program was used to analyze the cane and sucrose yields of 44 newly released sugarcane cultivars at eight pilot test sites. The cane and sucrose yields of nine cultivars were higher than those of the control cultivar ROC22. From the perspective of cane yield, cultivars FN 40 and YZ 06-407 were well adapted to a wider range of conditions and produced relatively high cane yields in several pilot sites. From the perspective of sucrose yield, cultivars LC 03-1137, FN 38, FN 41, MT 01-77 and LC 05-136 were well adapted to a wide range of conditions and produced relatively high sucrose yields. Based on these results, three high yielding and widely adapted cultivars, namely, FN 39, LC 05-136, and YZ 05-51 were recommended for production in three major Chinese sugarcane planting areas. The results will provide a theoretical basis for recommending the effective use and rational regional distribution of sugarcane cultivars in China.
