不同粒色谷子品系的鸟害程度研究

The Research on Bird-disaster Degree in Different Grain Colors of Foxtail Millet Lines

针对目前谷子生产上鸟害严重的问题,以褐粒谷子品系冀谷31和冀谷19为试验材料,以黄粒品系和红粒品系为对照,测定了不同粒色谷子品系鸟害的产量损失率和鸟饲食用率。结果表明:褐粒谷子品系冀谷31和冀谷19的产量损失率和鸟饲食用率均极显著<黄粒品系和红粒品系。证实了褐粒谷子品系冀谷31和冀谷19具有明显的鸟害轻的特点,其鸟害轻的主要原因在于粒色。本研究结果可为抗鸟害谷子品种的选育研究提供参考。

Based on the current serious bird-disaster problems in foxtail millet production , brown-red millet Jigu 31 and Jigu 19 were testet as materials and yellow grain line and red grain line for comparisons , bird-disaster loss rate and bird feeding rate of different grain color lines were measured .The results showed that loss rate of yield and bird feeding rate of Jigu 31 and Jigu 19 were highly significantly lower than yellow and red lines.It confirmed that brown-red grain of millet Jigu 31 and Jigu 19 had obvious characteristics of the bird-disaster light.This provided references for the breeding research of resistance to bird-disaster.
