摘要
为促进鲁西北地区优良谷子资源的利用,采用灰色关联分析方法,对鲁西北地区 17 个夏谷新品种(系)产量与农艺性状进行研究.调查和统计分析发现,影响谷子产量的7个农艺性状的关联度顺序为生育期>株高>穗数>单穗重>穗粒重>穗长>千粒重,其中生育期、株高、穗数、单穗重、穗粒重5个性状对谷子产量的关联度较高.因此,为促进鲁西北地区夏谷优质高产发展,应在满足正常发育成熟的前提下,选择生育期较长、株高较高、穗数较多的谷子品种.
Abstract
To promote the utilization of superior millet resources in northwest Shandong,the yield and agronomic characters of 17 new summer millet varieties in northwest Shandong were studied by grey correlation analysis.Through investigation and statistical analysis,it was found that among the agronomic traits affecting grain yield,the correlation sequence of the seven agronomic traits related to grain yield was in the order of growth date>plant height>ear number>ear weight per spike>ear weight per spike>ear length>1 000-grain weight.Among them,growth date,plant height,ear number,ear weight per spike and grain weight per spike had higher correlation with grain yield.Therefore,in order to promote the development of high quality and high yield of summer millet in northwest Shandong,we should choose the millet varieties with longer growth period,higher plant height and more ear under the premise of meeting the normal development and maturity.
