摘要:
本文探究高粱穗部主要性状的遗传特性,评价最新引进和培育的高粱亲本材料的利用价值,为高粱穗型育种提供理论依据和参考。以13163A、1358A、128A和407A 共4个高粱不育系,以及9.1R、213R、272R、381R、矮182R和早21R共 6个恢复系为试验材料,按照不完全双列杂交设计(NCII),对其F1代的穗部主要性状进行配合力分析。结果表明:亲本穗部主要性状存在显著的遗传差异,其主要表现为加性基因效应遗传的性状有:穗长、一级枝梗数、二级枝梗数、穗粒数;狭义遗传力大小顺序分别为:二级枝梗数>一级枝梗数>穗长>穗粒数>穗粒重>千粒重。不同亲本的一般配合力(GCA)和特殊配合力(SCA)在不同穗部性状间存在较大差异。不育系407A和恢复系早21R、9.1R是综合性状较好的亲本材料,利用它们可配出产量较高的杂交组合。恢复系272R其组配的杂交种具有穗粒数较多、千粒重较小的特点,能满足市场上对小粒高粱的需求。深入分析高粱杂交亲本穗部主要性状表现,有利于对亲本材料的进一步了解和利用。

Abstract:
To explore the main characters of the genetic features of sorghum panicle and evaluate the use value of material of latest introduction and cultivation of sorghum parents, thus providing theoretical basis for breeding of sorghum panicle and reference. Four sorghum sterile lines(13163A, 1358A, 128A and 407A ) and 6 restorer lines (9.1R, 213R, 272R, 381R, Dwarf182R and Early21R) were mated, the combining ability of main traits of F1 generation’s panicles was analyzed according to incomplete diallel cross(NCII). The results showed that the main panicle traits exist significant genetic differences, the main performance for the additive gene effect of genetic traits are: spike length, primary branches number, secondary branch number, grain numbe per spike; Narrow heritability size order are: secondary branch number > primary branch number > spike length> grain number per spike > grain weight per spike >1000-kernel weight. Different parent’s general combining ability (GCA) and specific combining ability (SCA) is significant difference in different traits. Sterile line 407A and restorer early 21R, 9.1R which has better comprehensive characteristic, have great potential applications in production of hybrid combinations. Restorer 272R combined with lower spike grain number and small grains characteristics can satisfy the market demand for small grain sorghum. In-depth analysis of sorghum hybrid parent main panicle traits, is conducive to the further understanding and use of parent material.
Key words:  Hybrid sorghum  Parent  Panicle traits  Combining ability  Value evaluation
