糯质高粱杂种一代存在明显的杂种优势,以穗粒重的优势最强;杂交双亲和中亲值对杂种一代的性状表现有不同程度的正向影响;除不育系间的穗粒重、一级分枝数的一般配合力和穗长的特殊配合力不显著外,其余性状存在极显著差异;株高、穗长、千粒重和一级分枝数在遗传表现中加性基因效应占主导地位,而穗粒重和穗粒数则以非加性基因效应为主。
The heterosis of glutinous sorghum hybrids had obvious heterosis in order to spike grain weight has the strongest advantage; hybrid parents and the pro-value of the hybrid generation traits have different degrees of positive effect; in addition to the sterile grain weight, There were extremely significant differences in the general combining ability of first-level branch number and the special combining ability of spike length. The additive gene effect was dominant in the genetic performance of plant height, spike length, 1000-grain weight and first-level branch number Position, while the grain weight per spike and grain number are based on non-additive gene effect.
