摘要
在干旱和半干旱地区,选择耐旱作物及品种是发展生产,齐发利用旱脊土地的有效措施之一。糜黍耐旱耐脊,蒸腾系数低,是北方旱作物农业的主栽作物之一。为了给糜黍育种和生产提供良好的耐旱资源,1987～1990年我们对不同生态类型的糜黍品种资源进行耐旱性鉴定,同时也为深入研究糜黍耐旱机理提供材料和依据。
Screening for germplasm resoures of Panicum Miliaceum to drought tolerance of different ecotype was studied by survival rate after repeated drought and grain yield under natural drought conditions. The result showed; (a) Dong Shen Er Huang Mi, Yi—Meng7619 and Yi Xuan Da Long Mi are fine germplasm resources of high yield and drought tolerance in the drought areas. (b) The lateral ear and round—grained nonglutinous character are important ecotype of Panicum Miliaceum to drought tolerance, (c) Screening for germplasm resoures of Panicum Miliaceum to drought tolerance should integrate with high yield and adaptability.
