摘要：

选择5份高粱不育系、16份高粱恢复系、及所配制的部分高粱杂交种，化验分析淀粉含量，不育系淀粉含量变幅在72.58%—77.84%之间，恢复系淀粉含量变幅在72.33%—79.93%之间，杂交种淀粉含量变幅在74.66%—77.61%之间。研究表明，淀粉性状在F1代具有明显的杂种优势，高粱籽粒淀粉含量在杂种一代多数介于双亲之间，有的倾向于高亲含量，有的倾向于低亲含量，有的杂种一代淀粉含量超过高亲，有的杂种一代淀粉含量低于低亲，利用高淀粉双亲，可以选育出高淀粉高粱杂交种。

Abstract:

5 sterile lines, 16 restorer of sorghum and their hybrids were studied in this paper. Their starch contents were detected and analyzed. The result showed starch contents of sterile lines were 72.58%-77.84%, restorer were 72.33%-79.93%, hybrids were 74.66%-77.61%.The heterosis of the F1 hybrids on starch content was significant, and their starch contents were between two parents, starch contents of some hybrids were apt to high parent content, some were apt to low parent content, some were higher than high parent content, some were lower than low parent content. High starch content sorghum hybrids can be bred by high starch content parents.
