本文主要研究内容
作者龚锡震（2019）在《不同类型种质玉米青贮特性筛选鉴定》一文中研究指出：本试验以13个不同类型种质玉米自交系为亲本(8个父本,5个母本),按NCII设计组配40个杂交玉米组合。对41个组合(含1个CK品种,下同)采用随机区组设计进行一年3点联合鉴定试验。通过对不同杂交组合小区生物产量及影响生物产量关键农艺性状和品质性状综合分析,从而对杂交组合和亲本自交系进行玉米青贮特性的综合评价。主要研究结果如下:1、对不同杂交玉米组合的生物产量及影响生物产量关键农艺性状和青贮品质性状进行比较分析,其中组合黄C×S273、黄C×交51、NG5×交51、PH6WC×T32、NG5×T32、黄C×T32、NG5×CML171、NG5×R65、黄C×CML171、PH6WC×Z78、郑58×T32的综合性状表现较好。2、配合力分析表明:综合考虑各性状的GCA、SCA效应值,13个玉米自交系中黄C、NG5、T32、交51、FN004的生物产量及影响生物产量关键农艺性状的GCA表现较好,自交系郑58、黄C、昌7-2、Z78的青贮品质GCA表现较好。根据各杂交玉米组合生物产量及影响生物产量关键农艺性状和品质性状的SCA效应值来看,在多数性状上SCA表现较好的组合有Y3052×R65、PH6WC×Z78、郑58×T32、黄C×S273、NG5×交51、郑58×CML171。3、小区生物产量杂种优势分析表明:通过对40个杂交组合小区生物产量进行总配合力效应值计算,多数杂交组合的TCA效应值为正,表明40个杂交组合中存在优势组合,杂交组合生物产量总配合力排名前十位的组合中有4个组合是以T32为父本,3个组合以FNOO4为父本,2个组合以交51为父本,以NG5和PH6WC为母本的组合各有3个,以黄C为母本的组合有2个,说明T32、FN004、交51、NG5、PH6WC、黄C等自交系易组配出生物产量高,适合做青贮的杂交玉米组合。对生物产量前10的杂交玉米组合进行杂种优势模式分析,这些组合的杂种优势模式大致可以分为3类,其中Reid群×热带种质群模式的有7个组合,占总量的70%;Reid群×贵州地方种质有2个组合,占20%;Lancaster群×78599群的有1个组合,占10%。4、采用Duncan’s新复极差法对杂交组合进行丰产性分析,结果表明40个杂交组合比对照增产的组合有17个,增产幅度为1.04%—16.37%,这17个组合由父本自交系T32和FN004配制的组合各有5个,交51组配的有3个,母本自交系黄C和NG5组配的各有4个,与生物产量及影响生物产量关键农艺性状GCA分析结果基本一致。通过利用变异系数法、回归系数法、高稳系数法对41个杂交玉米组合进行稳定性分析,结果表明:这3种方法的评价结果有一定的差异,但大体保持一致,对稳定性好的组合的亲本进行分析,可以筛选出由自交系PH6WC、黄C、CML171、FN004、R65配制的组合稳定性较好。5、杂交玉米组合的生物产量性状和影响生物产量关键农艺性状之间存在一定的相关性,可以通过较好的农艺性状来间接选择生物产量高的组合。品质性状间也存在着相关性,可以对多个品质性状同时进行选择。由各性状间存在相关性表明,在选育青贮玉米组合时,应协调好各性状之间的关系。
