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。
