糜子品种抗倒伏试验研究

Experimental Study on Lodging Resistance of Millet Varieties

该文采用倒伏系数和田间倒伏面积对比的方法,对内糜5号、内糜6号、内糜7号、内糜8号、内糜9号、伊选黄糜等6个主栽糜子品种进行了抗倒伏试验研究。结果表明,内糜5号、内糜6号、内糜8号、内糜9号的倒伏系数小于1.0,抗倒伏能力较强,内糜7号和伊选黄糜倒伏系数大于1.0,抗倒伏能力较弱,易发生大面积倒伏现象。在今后的糜子育种工作中,应努力提高糜子单茎根量和茎秆机械强度,降低植株高度,以增强其抗根倒伏能力。

This experiment studied Neimi No.5,Neimi No.6,Neimi No.7,Neimi No.8,Neimi No.9 and Yixuanhuang-mi etc. six main planting millet varieties lodging resistance with the method by adopting lodging coefficient and lodg-ing in the field area of comparison. The results showed that,lodging coefficient of Neimi No.5,Neimi No.6,NeimiNo.8 and Neimi No.9 were less than 1.0,lodging resistance ability was strong,lodging coefficien of Neimi No.7 andYixuanhuangmi were greater than 1.0,lodging resistance ability was weak,proned to the phenomenon of a large areaof lodging. During the selective breeding of millet in future,we should try to improve the millet root weight and culmmechanical strength,reduce plant height in order to enhance its resistance about root lodging resistance.
