华北夏谷区近30年来主要谷子育成品种农艺和品质性状演变分析
Evolution of Agronomic and Quality Traits of Main Foxtail Millet Varieties in North China Bred in Past Thirty Years
摘要
Abstract
In order to provide the theoretical basis for breeding foxtail millet variety,the agronomic and quality traits of 20 foxtail millet varieties bred in North China in the recent 30 years were investigated.The results showed that the yields of these foxtail millet varieties increased annually by 29 kg/hm2;the spike length,spike weight,grain weight per spike and stem diameter increased;the spike diameter and plant height decreased.The decrease of plant height and increase of stem diameter were conducive to improve the lodging resistance of foxtail millet varieties.The correlation analysis indicated that the correlation coefficient of traits with yield decreased in the order of spike length,spike diameter,grain weight per spike,spike weight,plant height,stem diameter,heading days,thousand seed weight,among them,the thousand seed weight and heading days had less effect on yield.The nutrition quality of foxtail millet varieties bred recently in North China improved little in total,which should be paid more attention.关键词
