黍稷种质的倒伏性是造成黍稷减产的一大要素,如何防止黍稷的倒伏,筛选和培育抗倒的黍稷种质是解决黍稷倒伏最根本和有效的方法。本文对山西省的1192份黍稷种质资源进行了抗倒性鉴定,筛选出71份高抗倒性的种质提供生产和育种利用。同时对倒伏性和抗倒性进行了研究。进一步明确了倒伏性分为茎倒和根倒2种类型,而茎倒和根倒的形成又与生态环境有密切的关系,是生态型的具体体现。抗倒性与茎部和根部的形态特征关系密切,通过0级高抗倒种质与3级不抗倒种质茎部和根部形态特征的比较,说明0级高抗倒种质在茎部和根部形态特征上所占的优势,是形成高抗倒的重要原因。
The breeding and rebirth of Broomcorn millet Germplasm resources is a long-term and systemic basic research work. In order to standardize the breeding and rebirth technique, the article describes the breeding and rebirth technical operation specification systemically from the following aspects: variety of Broomcorn millet Germplasm resources, breeding characteristics of different type Broomcorn millet Germplasm resources, biology base and breeding characteristics of Broomcorn millet, main technical standard and work procedure of Broomcorn millet breeding, which will supply reference and guidance for the later breeding and rebirth of Broomcorn millet Germplasm resources.
