摘要: 本文采用Hayman双列分析法分析了一套糯高粱不完全双列杂交资料6个数量性状的遗传参数。结果表明:株高和一级分枝数的遗传符合加性——显性——上位性模型,单穗粒数、单穗粒重和千粒重符合加性——显性模型。除单穗粒重以显性效应重要外,其余性状以加性效应为主。株高和一级分枝数的狭义遗传力较高。控制这些性状的显性基因为增效基因。泸72A含有较多的控制单穗粒数和单穗粒重的显性基因,R29则含有较多的控制除千粒重外的其它4个性状的显性基因,它们是值得育种者重点利用的育种材料。

Abstract: This paper, according to Hayman's method, Presents a diallel analysis of 6 quantitative characters in 4 glutinous male sterile lines and 5 glutinous restoring lines of sorghum from a set of incomplete diallel crosses.The results showed that the three traits (No.of grains per panicle, grain weight per panicle and 1000-grain weight) with the exception of plant height and No.of primaries per panicle were adequate to the additive-dominant genetic model.There were a great number of dominant genic effects in the control of grain weight per panicle, the additive genic effects were more important than the dominant genic effects in plant height, No.of primaries per panicle, NO.of grains per panicle and 1000-grain weight.The dominant genes in the control of them were effectincreasing genes.Lu72A and R29, which are better glutinous breeding materials for improving plant height and spike traits, are worth being used with emphasis in future breeding.
