摘要
对夏谷新品种(系)产量和性状的灰色关联分析表明,在不同产量水平下,各性状对产量的作用不同。低产条件下,几个性状对产量的灰色关联序依次为单株粒重>单穗重>每公顷穗数>千粒重>出谷率>穗长;中产条件下,关联序为出谷率>每公顷穗数>千粒重>单株粒重>单穗重>穗长;高产条件下,关联序为千粒重>出谷率>每公顷穗数>穗长>单株粒重>单穗重。
Grey correlative degree analysis between yield and the related characters of millet varieties was conducted. The results indicated that characters have a different effect on grain yield at different yielding level. In low-yield field, the sequence of grey correlation degree of the Characters to yield was, grain weight per plant, spike weight, the numbers of spike per hectare, thousand kernel weight, milled millet percentage, spike length. In the middle yield field, the sequence was:milled millet percentage, the number of spike per hectare, thousand kernels weight, kernel weight per plant, spike weight per plant, and spike length. While at high yield field, the sequence was: thousand kernel weight, milled millet percentage, spike number per hectare, spike length, kernel weight per plant and spike weight per plant.
