摘要
为了提高半干旱地区糜子的抗倒伏性,采用倒伏系数对糜子的抗倒伏性进行相关及通径分析。结果表明:倒伏系数与倒伏程度成显著正相关,说明采用倒伏系数评价糜子抗根倒伏性是客观、准确的。在糜子育种工作中,应努力提高糜子单茎根干重,以增强其抗根倒伏能力。
In order to improve the lodging resistance of millet in semi-Arid Area, lodging resistance of millet was analyzed by lodging coefficient. The results showed that there was significant positive correlation between the lodging coefficients and lodging degree, these could prove that the lodging coefficient could evaluate the lodging resistance of millet objectively and accurately. In the breeding work of millet, efforts should be made to improve the single root dry weight of millet, to enhance its ability of anti-root lodging.
