The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

Variation and broad-sense heritability (H2) of the three characters: CV and H2 of self-pollinated fruiting rate were both greatest

均单果重等性状在F1中广泛分离，杂种群体的平均值低于亲中值，表现明显的衰退现象，表明这3 个性状均为数

But significant differences were found in coefficient of variation and broad-sense heritability (H2) of the three characters: CV and H2 of self-pollinated fruiting rate were both greatest, with the variation mainly resulted from inheritance, and high inheritance potential; H2 of fertile flower rate was the least and its variation was less from inheritance; CV of average fruit weight was the least and its inheritance potential is small. Thirdly, the ratios of sweet to bitter kernel of F1 progenies in positive and reverse crosses between Katy and Taianshuixing were 18∶16 and 13∶12, and were both in agreement with a 1∶1 segregation by χ2 test, which demonstrated that the bitter kernel character of Katy was heterozygous.

但3个性状的变异系数和广义遗传力(H2)均差异很大，其中自交坐果率的变异系数(101.5%～139.1%)和广义遗传力(87.1%～91.4%)均较大，表明变异主要来自遗传效应，并且自交坐果率的遗传潜能大；有效花比率的广义遗传力最小(36.8%～49.1%)，表明其遗传效应较小；平均单果重的变异系数最小(24.0%～29.7%)，说明平均单果重的遗传潜能小；（3）凯特与泰安水杏正反交的杂种一代甜仁与苦仁的比例分别为18∶16和13∶12，经χ2检验符合1∶1的分离比例，证明控制凯特杏甜仁与苦仁这对性状的基因位点是杂合的。
