摘　　要：黍稷种质资源的倒伏性是固有的生态型表现,与生态环境密切相关。因此,高抗倒种质的推广利用也要因地制宜。本文通过对山西省晋北、晋中、晋南3个不同生态区黍稷种质资源的倒伏程度,倒伏程度与生育期、茎粗的关系和倒伏类型的分析研究,说明鉴定筛选出的黍稷高抗倒种质,也要因地制宜推广利用。在栽培技术上也要采取相应的抗倒措施,只有这样,才能把黍稷种质资源因倒伏造成的损失降到最低。The lodge of Proso millet germplasm resources is an inherent ecological performance, which is closely related to the ecological environment. Therefore, the promotion and utilization of the high anti-reverse germplasm is also suitable for local conditions. In this paper, Proso millet germplasm resources of lodging and the relationship between lodging degree and growth period, stem diameter as well as lodging type were analyzed and researched in the three different ecological regions of southern, northern and middle regions of Shanxi Province. The result suggests that identification of Proso millet and screening high lodging resistant germplasm should adjust to local conditions for popularization and utilization. It is also necessary to take corresponding anti-re- verse measures in the cultivation techniques, so that the loss of the Proso millet germplasm resources will be minimized.
