对甘蔗８个亲本品种及其选配的１５个组合生物量的配合力分析表明，甘蔗的生物量遗传主要是由基因加性效应决定的；母本ｇｃａ方差大于父本ｇｃａ方差，说明甘蔗生物量育种中母本选择的重要性。地上部鲜重的ｈＢ２在７０％以上，暗示它在早期阶段选择效果较好。研究发现生物量ｇｃａ效应高的亲本为Ｃｏ１００１，Ｃｐ７２－１２１０和ｙａ９０－３３，可作为生物量育种的亲本加以利用。根据配合力总效应评价组合，认为Ｃｏ１００１×Ｙａ８９－２６、Ｃｏ４１９×Ｙａ９０－３３、Ｃｏ１００１×Ｙａ９０－３３、Ｃｏ１００１×Ｙａ７３－２２６、Ｃｐ７２－１２１０×Ｙａ９０－３３、Ｃｐ７２－１２１０×Ｙａ７３－２２６是生物量高的组合，可以用于甘蔗的高生物量育种。
The analysis of combining ability of 15 parents and 8 parents of sugarcane showed that the biomass of sugarcane was mainly determined by gene additive effect. The variance of female gca was greater than that of male gca The importance of choice of female parent in breeding. Above the fresh weight of hB2 above 70%, suggesting that it is better in the early stages of selection. The results showed that the parents with high gca effect on biomass were Co1001, Cp72-1210 and ya90-33, which could be used as the parents of biomass breeding. According to the total combining effect evaluation, Co1001 × Ya89-26, Co419 × Ya90-33, Co1001 × Ya90-33, Co1001 × Ya73-226, Cp72-1210 × Ya90-33 and Cp72-1210 × Ya73-226 are considered as biological High amount of combinations, can be used for high biomass breeding sugarcane.
