| 摘 要： | 报道了甘蔗与斑茅远缘杂交利用研究结果。本研究利用斑茅及其F1、BC1与甘蔗热带种、栽培种杂交和回交获得了一些斑茅的F1、BC1、BC2真实杂交种。结果表明:斑茅的F1、BC1的结实率低,育性低甚至不育,但通过回交可以提高斑茅杂种的结实率,且回交得到的BC1、BC2表现出了生势强,产量高、锤度高的优势,为选育具有斑茅血缘的高产高糖种质奠定了良好的基础。 |

| Abstract: | Progress of distant hybridization utilization between Saccharum and Erianthus arundinaceus were reported in this paper.Erianthus arundinaceus F1 and BC1 and BC2 real hybrids have been obtained through crossing and backcrossing between Erianthus arundinaceus and Erianthus arundinaceus F1 and BC1 and Saccharum officinarum or cultivares.The results showed that setting percentage of Erianthus arundinaceus F1 and BC1 was low,their fertile was low and infertile,but low setting percentage of Erianthus arundinaceus F1 and BC1 was improved by backcrossing,and Erianthus arundinaceus BC1 and BC2 hybrids of backcrossing showed stronger vigor and high yield and sucrose abilities.It should be established well bases for breeding high yield and sucrose sugarcane clones with consanguinity of Erianthus arundinaceus. |
